The MBTA Commuter Rail functions as the commuter rail segment of the Massachusetts Bay Transportation Authority (MBTA), serving the Greater Boston region. This network runs over 450 miles of track, encompassing 12 lines and 143 stations, managed under contract by Keolis.

In , the system handled an annual ridership totaling , with weekday averages around as reported in . This places it as the fifth-largest commuter rail network in the United States, trailing behind New York’s three systems and Chicago's Metra.

The rail lines stretch southward to North Kingstown, Rhode Island, northward to Newburyport, and westward to Fitchburg. Services originate from two principal Boston terminals—South Station and North Station. The only physical connection between these two terminals is the non-revenue Grand Junction Branch. Plans for the North–South Rail Link tunnel intend to link North and South Stations, enabling continuous through-running trains.

Lines

The system consists of twelve lines—four of which include branches—that radiate out from downtown Boston. Of these, eight "southside" lines terminate at South Station, with four lines (Framingham/Worcester, Needham, Franklin/Foxboro, and Providence/Stoughton) also stopping at Back Bay station. The remaining four "northside" lines conclude at North Station. Line distances vary from the short Fairmount Line to the extensive Providence/Stoughton Line, generally spanning between 9 and 63 miles. The network encompasses approximately 450 miles of revenue track across eastern Massachusetts and central Rhode Island.

Most routes operate on separate tracks beyond their Boston terminals; however, there are exceptions. The Providence/Stoughton and Franklin/Foxboro Lines share the Northeast Corridor between and South Station; the Needham Line shares its tracks between and South Station; the Fall River/New Bedford, Kingston, and Greenbush Lines run along the Old Colony mainline between South Station and Braintree, Massachusetts. Additionally, the Haverhill and Newburyport/Rockport Lines share trackage between North Station and near . Certain Haverhill trains utilize the inner Lowell Line and Wildcat Branch, while some Franklin/Foxboro weekend services run via the Fairmount Line instead of the Northeast Corridor. Several Amtrak intercity services operate on MBTA-owned tracks: including the and on the Providence/Stoughton Line; the on the Framingham/Worcester Line; and the on segments of Lowell and Haverhill lines. Private freight companies also make use of much of this rail infrastructure (see ).

Stations

The MBTA Commuter Rail currently manages 143 operational stations, with 56 located on the north side and 87 on the south side. Following service reductions due to the COVID-19 pandemic, five stations (, , , , and ) remain closed indefinitely. Plans for additional station developments are underway. Major interchange points such as South Station, North Station, and Back Bay provide connections to both MBTA subway lines and Amtrak services; meanwhile, nine other stations offer subway transfers, and six serve as Amtrak connection points.

Station infrastructure ranges from minimal platforms like to large-scale urban terminals. Most suburban stops have either one or two side platforms or a single island platform. The typical MBTA platform length is approximately , designed to accommodate trains consisting of nine cars, with side platforms being at least wide and island platforms wide. Among the active stations, 122 are equipped for accessibility, including all terminal stations and those linked to rapid transit; however, 21 stations do not have accessible features. The MBTA utilizes -high platforms to facilitate level boarding, in line with standards common in the northeastern United States. Some accessible locations feature full-length high platforms, while others utilize "mini-high" platforms about long that support level boarding for two train cars only.

Operations

Keolis Commuter Services, a subsidiary of the French firm Keolis, operates the MBTA Commuter Rail under contract with the MBTA. Ownership of all passenger rolling stock, most station facilities, and the majority of track infrastructure rests with the MBTA. The Massachusetts Department of Transportation, which oversees the MBTA, holds ownership of certain sections of the Framingham/Worcester Line and the Grand Junction Branch, which is primarily used for non-revenue equipment transfers. The Fitchburg Line segment between and Wachusett is owned by Pan Am Southern, while Amtrak controls the Northeast Corridor portion within Rhode Island utilized by the Providence/Stoughton Line.

Service schedules typically maintain consistent headways with increased frequency during peak periods. Service frequencies vary significantly: for example, the Greenbush and Kingston lines operate 13 weekday round trips each, whereas the Providence/Stoughton Line offers up to 37. Trip durations span from roughly 30 minutes on the Fairmount Line to nearly two hours on some Providence/Stoughton runs, with most journeys lasting between one hour and one hour fifteen minutes. The majority of trains make stops at every station along their routes; however, some provide limited-stop or express service during peak times. Certain lines also run short-turn services. On weekends, the seasonal CapeFlyer employs MBTA equipment over the Middleborough/Lakeville and Cape Main Lines. Special express trains to Foxboro station run during New England Patriots home games and other events at Gillette Stadium, departing from South Station via the Franklin/Foxboro Line and from Providence via the Providence/Stoughton Line. Additionally, a winter "ski train" operates round trips on the Fitchburg Line, featuring a bicycle car and shuttle bus service to Wachusett Mountain.

All commuter rail operations utilize push-pull train sets powered by diesel locomotives (refer to ). Trains can reach speeds up to , although some routes impose lower maximum speeds. The entire system incorporates signaling technology along with Positive Train Control implemented through the Advanced Civil Speed Enforcement System. Cab signaling enables automatic train control across all lines. The MBTA adheres to Northeast Operating Rules Advisory Committee (NORAC) standards—primarily rules 261 and 562—allowing bi-directional train movements on every track segment. Most routes consist of double tracks or single tracks equipped with passing sidings; certain portions of the Northeast Corridor include three or four tracks.

Freight operations

Freight transportation utilizes most of the MBTA Commuter Rail network through various private rail companies. On the southside routes, CSX Transportation oversees freight services, with the outer segment of the Worcester Line handling the greatest freight traffic. The Massachusetts Coastal Railroad operates freight south of Middleborough along the Fall River/New Bedford corridor. Between Braintree Yard and East Braintree on the Old Colony mainline and Greenbush Line, the Fore River Railroad manages freight movement. The Providence and Worcester Railroad shares track usage with Providence/Stoughton Line passenger trains between Providence and Wickford Junction, while it runs exclusively on a freight-only track from Providence to Central Falls. Freight services are absent on the Needham Line, the Northeast Corridor segment between Readville and Back Bay, the Old Colony mainline from Boston to Greenbush Junction in Braintree, Kingston Line, and most portions of the Greenbush Line.

On northside routes, CSX assumed control from Pan Am Railways in 2022. West of Ayer on the Fitchburg Line, freight operations are conducted by the Berkshire and Eastern Railroad (previously known as Pan Am Southern). Their combined Freight Main Line stretches from Mechanicville, New York to Mattawamkeag, Maine, sharing track segments with Fitchburg, Lowell, and Haverhill commuter lines. Freight traffic does not extend northward beyond on the Newburyport/Rockport Line.

Weight restrictions and clearance profiles differ across lines: the entire Framingham/Worcester route supports car weights up to , while sections of the Freight Main Line allow up to . Other segments have more restrictive limits. The western portion of Framingham/Worcester and southern Providence/Stoughton lines accommodate cars classified under AAR Plate H/K (up to ). Fitchburg west of Ayer permits Plate J loading gauge (), whereas most other northside routes allow a maximum of Plate F (). Height constraints below Plate F apply to inner Fitchburg, Newburyport/Rockport Lines, and all southside lines except for the outer Framingham/Worcester section.

Fare structure

The MBTA Commuter Rail uses a zone-based pricing model, where ticket costs increase relative to travel distance. Zone 1A includes downtown terminals and nearby stations within approximately of downtown Boston. Beyond this core zone, ten additional zones (1 through 10) radiate outward in increments of about 5 miles each. Most distant terminals fall within Zones 6 through 8; only and are classified in Zones 9 and 10 respectively. Fares within Zone 1A align with MBTA subway pricing; however, subway passes loaded on CharlieCards are generally not accepted except at Fairmount Line stations equipped with validators. As of , single-ride fares in Zone 1A are priced at $2.40, while fares between Zone 1A and farther zones range from $6.50 for Zone 1 up to $13.25 for Zone 10. Trips crossing zones without passing through Zone 1A cost less, starting at $2.75 for travel within one zone and reaching $7.25 between Zones 1 and 10.

Tickets are available through multiple channels including the MBTA mTicket smartphone app, ticket vending machines at major stations, select local retailers, or directly from onboard conductors. Various discounted fare options exist such as monthly passes (with or without MBTA transfer privileges), "flex passes" valid for five separate 24-hour periods, and $10 unlimited weekend passes. Reduced fare eligibility extends to seniors aged 65 and older, disabled riders, and certain student groups. Special event trains like those serving Foxboro or the CapeFlyer operate under distinct fare structures; standard MBTA passes do not apply on these services.

Fare collection is performed by conductors onboard trains; although fare evasion is prohibited by law, it is not treated as a criminal offense under Massachusetts statutes. Faregates have been installed at North Station with future plans to implement similar systems at Back Bay and South Station terminals. The forthcoming second-generation MBTA fare system, anticipated by 2025, aims to integrate fare media across all transit modes and enable full CharlieCard compatibility for commuter rail journeys.

Early history

From 1834 to 1855, Boston was connected by eight principal intercity railroads: the Boston and Worcester Railroad (B&W), Boston and Providence Railroad (B&P), Boston and Lowell Railroad (B&L), Eastern Railroad, Fitchburg Railroad, Boston and Maine Railroad (B&M), Old Colony Railroad, Fall River Railroad, and Norfolk County Railroad. The inception of commuter rail service began in 1834 with the B&W, facilitating travel for suburban workers into Boston. By the 1860s, commuting options expanded along these main routes as well as several branch lines. Initial mergers aimed to unify branches and link lines, exemplified by the 1874 consolidation of the B&A with the Western Railroad to establish the Boston and Albany Railroad (B&A). The narrow gauge Boston, Revere Beach and Lynn Railroad (BRB&L), launched in 1875, rivaled the Eastern Railroad but depended on ferry connections rather than direct access to downtown Boston.

The B&M extended its dominance north of Boston by acquiring the Eastern in 1883, the B&L in 1887, and the Fitchburg in 1900. Construction of North Union Station occurred in 1893 to serve northern routes, later replaced by North Station in 1928. The Old Colony took over the B&P in 1888; shortly after, the New York, New Haven and Hartford Railroad (New Haven) absorbed Old Colony in 1893 and the New England Railroad (successor to NY&NE) in 1898. South Station was inaugurated in 1899 as a union terminal for southern lines operated by New Haven and B&A. In 1900, the New York Central leased the B&A, consolidating Boston’s commuter rail under three primary multi-state railroads, excluding BRB&L.

At the dawn of the 20th century, these three major railroads considered suburban electrification projects. The New Haven experimented with electrifying sections of Old Colony but did not extend this to South Station or inner ex-B&P lines. The NYC electrified only a brief segment known as the Lower Falls Branch despite studies evaluating wider electrification. Around 1910, B&M proposed quadruple-tracking and electrifying part of its former Eastern line but abandoned these plans after separating from New Haven. Commuter rail service reached its peak near 1910 before experiencing declines attributed to competition from streetcars and automobiles. The independent BRB&L electrified its mainline in 1928, nearing rapid transit standards; meanwhile, two Old Colony branches were converted into rapid transit extensions by Boston Elevated Railway (BERy) during the 1920s.

The 1930s saw a steep reduction in service levels; notably, the 88 stations case prompted New Haven to shut down numerous suburban stations and routes in 1938. BRB&L ceased operations entirely by 1940. Although World War II temporarily increased ridership, postwar trends led to further cutbacks. During the 1950s, railroads transitioned from steam locomotives to diesel power, heavily investing in fleets of Budd Rail Diesel Cars to lower operating costs—though this strategy failed to preserve most branch lines. A state report issued between 1945 and 1947 recommended expanding rapid transit along existing railroad corridors while scaling back commuter rail services. Subsequently, portions of BRB&L were reactivated as rapid transit by Metropolitan Transit Authority (MTA) between 1952 and 1954, and the Highland branch was transformed into a rapid streetcar line (now known as Green Line D branch) by 1958–59.

MBTA Assumes Control and Consolidates Services

Between 1958 and 1960, suburban rail services operated by the three main railroads were drastically reduced as commuters increasingly favored expressway travel. The Boston and Maine Railroad (B&M) experienced financial losses beginning in 1958, prompting it to discontinue unprofitable passenger operations and close several branch lines and stations within the Metropolitan Transit Authority (MTA) region. Meanwhile, the New Haven Railroad temporarily boosted service on the Old Colony Division but eliminated routes to Fall River and New Bedford in 1958; remaining Old Colony operations ceased altogether in 1959 following the opening of the Southeast Expressway. By 1960, the Boston and Albany Railroad (B&A) had scaled back track usage and shuttered local stops west of Framingham. The New Haven's bankruptcy filing in 1961 spurred public demand for government-supported commuter rail subsidies.

Established in 1959, the Massachusetts Mass Transportation Commission (MTC) conducted trials on fares and service patterns, determining that increasing train frequency was essential for boosting ridership, whereas reducing fares attracted passengers but did not guarantee financial sustainability. Acting on MTC’s guidance, the Massachusetts Bay Transportation Authority (MBTA) was created on August 3, 1964, encompassing a funding and service district spanning 78 municipalities. The MBTA’s strategy involved extending rapid transit on select lines while subsidizing others or discontinuing less viable routes; municipalities outside this district were responsible for arranging their own subsidy agreements.

On December 14, 1964, the MBTA finalized a subsidy contract with B&M to cover services within the district. By January 1965, B&M curtailed most interstate routes except for limited commuter runs originating from Dover and Concord in New Hampshire, and reduced Portsmouth service to a single round trip to Newburyport. Subsidies commenced for six lines on January 18; however, out-of-district services to Fitchburg, Lowell, Haverhill, Ipswich, and Rockport were mostly eliminated except for a few limited trips. After overcoming legal obstacles, full service resumed to Ayer, Lowell, Ipswich, and Rockport on June 28. The Concord route was discontinued in 1967; Dover service was truncated to Haverhill with local funding support. In 1969, B&M carried an average weekday ridership of 24,000 but operated at a $3.2 million annual loss. The Central Massachusetts Branch’s lone daily trip ended in January 1971.

On July 28, 1965, the MBTA agreed to acquire an 11-mile segment of the former Old Colony mainline stretching from Fort Point Channel to South Braintree for future rapid transit development. Concurrently, the MBTA committed to subsidize New Haven’s remaining commuter routes with an annual allocation of $1.2 million. Subsidies began in April 1966 for the Needham, Millis, Dedham, and Franklin lines; three stations outside the district were closed while Franklin arranged its own subsidy to maintain service. The Millis and Dedham branches were discontinued in April 1967. In February 1968, New York Central and Pennsylvania Railroads merged into Penn Central; New Haven was integrated by year-end. Penn Central declared bankruptcy in 1970. Amtrak assumed control of most intercity passenger operations on May 1, 1971.

To prevent asset liquidation during Penn Central's bankruptcy proceedings, the state purchased 145 miles of its rights-of-way in December 1971; ownership transferred to the MBTA effective January 27, 1973. This acquisition included vital passenger corridors such as the Attleboro Line with Stoughton Branch, Franklin Branch, Needham Branch, and the Riverside–Framingham portion of the Worcester Main Line. Freight-only or abandoned tracks like the Old Colony mainline between Braintree and Brockton were also obtained. Subsidies expanded over time: Framingham Line service began receiving support in January 1973; Canton Junction and Sharon stations followed in June; full Providence/Stoughton Line service was subsidized by September 1976. Additionally, in September 1973, MBTA purchased B&M’s Western Route between Somerville and Wilmington Junction to facilitate construction of the Haymarket North Extension.

Between 1967 and 1973, state funding covered most subsidies outside the MBTA district but was reduced to a 50% share starting January 1974—transferring greater financial responsibility onto municipalities. As some towns declined increased subsidy demands, several service reductions occurred: Ayer service was cut back to South Acton in March 1975; a single Newburyport trip ended in April 1976; Haverhill’s single trip ceased in June that year. The Worcester route’s lone round trip—which had never received subsidies—was truncated to Framingham in October 1975; however, Amtrak reinstated Worcester rail service four days later with its Lake Shore Limited train. To prevent further cutbacks, state subsidies were increased back to a 75% share by June 1976.

Integrated Operations

By 1971, expansions of rapid transit were confined to the initial segment of the Red Line Braintree Branch. In 1972, Governor Francis Sargent initiated the Commuter Rail Improvement Program, redirecting funds from highway projects to transit development. On October 8, 1974, the MBTA introduced purple as the official color representing the commuter rail system, unifying the B&M and Penn Central lines on system maps into a single network.

In 1976, Penn Central operations were transferred to Conrail, and the MBTA acquired most of their commuter rail equipment. After delays caused by B&M's bankruptcy, on December 27, 1976, the MBTA purchased B&M’s commuter rail rolling stock, maintenance facilities, and right of way—encompassing all passenger routes along with some freight and abandoned lines. This purchase led to a five-year operating contract with B&M, replacing previous one-year agreements. The MBTA also standardized its rolling stock livery using purple, yellow, silver, and black to create a cohesive visual brand.

Federal funding maintained MBTA payments to Penn Central until March 1977. Owning both the infrastructure and equipment allowed the MBTA to solicit bids for operations; B&M secured the contract and began managing southside commuter lines on March 15, 1977—marking the first occasion when all Boston-area commuter rail services were operated by a single company. Despite comprehensive subsidies, service reductions occurred: the lightly traveled Lexington Branch was closed following a snowstorm in 1977; Rhode Island’s decreased financial support led to cuts in off-peak service in 1979 and termination of peak service by 1981; and service on the Woburn Branch ended in January 1981 due to budget limitations.

The energy crises of the 1970s and the establishment of regional transit authorities stimulated system growth. Beginning in 1977, $70 million (1969 dollars) in federally funded reconstruction efforts enhanced the Franklin Line and several northside routes under the Commuter Rail Improvement Program. Service was restored to Haverhill in December 1979 and extended to additional destinations in January 1980. Pilot services operated from January 1980 to March 1981 reaching Nashua, Manchester, and Concord in New Hampshire. While some stations closed during the 1980s due to low patronage, several infill stations were introduced: (1981), (1982), (1984), and (1985). The MBTA also upgraded its fleet by acquiring 18 EMD F40PH diesel locomotives and 60 passenger cars delivered between 1978 and 1980.

Significant interruptions took place in the mid-1980s: on January 20, 1984, a fire destroyed wooden trestles at North Station drawbridges, necessitating temporary terminal arrangements with rapid transit connections during repairs. Another fire on November 16, 1984 between Beverly and Salem disrupted service on part of the Ipswich/Rockport Line. Full operations at North Station resumed on April 20, 1985; Ipswich and Rockport services restarted on December 1, 1985.

In 1983, Guilford Transportation Industries acquired B&M without immediately altering commuter rail operations. However, Guilford’s cost-cutting measures strained labor relations, resulting in two strikes; the first strike halted commuter rail service from March through May 1986. Media criticism followed Guilford’s refusal to renew its operating contract expiring at year-end. Amtrak subsequently won the contract and took over operations starting January 1, 1987. Due to disagreements among Amtrak, Guilford, and MBTA, service on the Gardner line was truncated back to Fitchburg.

Expansions

The late 1980s witnessed major expansions of the system. Completed in 1987, the Southwest Corridor project introduced a new underground route accommodating commuter rail, Amtrak, and Orange Line trains. Transfer hubs were enhanced with the reconstruction of Back Bay and Forest Hills stations, while Ruggles station was inaugurated to serve the expanding Longwood Medical Area. After being closed since 1979, the Needham Line resumed operations. The Attleboro and Franklin lines, which had been temporarily rerouted during construction, returned to the Southwest Corridor; meanwhile, a shuttle service continued as the Fairmount Line. Peak-hour trips to Providence restarted in 1988, with off-peak and weekend services added subsequently. South Attleboro station opened in 1990 as a park-and-ride facility replacing Pawtucket–Central Falls. The Franklin Line extended service to Forge Park/495 in 1988, and new infill stations included Yawkey (1988), serving Fenway Park, and Dedham Corporate Center (1990).

Massachusetts had implemented state accessibility regulations since 1977, preceding the 1990 Americans with Disabilities Act. The MBTA occasionally faced regulatory disputes over stations lacking accessibility features such as West Natick and Chelsea, resulting in fines. The opening of South Attleboro was postponed due to objections against constructing full-length high-level platforms. Nevertheless, accessibility improvements progressed steadily: stations on the Ipswich/Rockport line were upgraded during closures in 1984–85; South Station became accessible by the late 1980s; Back Bay was made accessible during the Southwest Corridor project; and North Station followed suit in the early 1990s. By 1992, accessibility had been achieved at 44 commuter rail stations.

In 1991, under a settlement addressing emissions from the Central Artery/Tunnel Project, Massachusetts committed to transit expansions including extending the Framingham Line to Worcester, expanding the Ipswich/Rockport Line to Newburyport, restoring Old Colony Lines (Middleborough/Lakeville and Plymouth/Kingston), and creating 20,000 park-and-ride spaces outside city centers. Peak-hour service to Worcester commenced in 1994, with off-peak and weekend service added later; four intermediate stations opened between 2000 and 2002. Service on the Old Colony Lines began in 1997; Newburyport and Rowley stations opened in 1998. The MBTA Commuter Rail Maintenance Facility replaced the Boston Engine Terminal in 1998.

In July 2003, MBCR—a consortium comprising Connex (Veolia), Bombardier Transportation, and Alternate Concepts—secured the contract to operate commuter rail services from Amtrak. This contract was extended multiple times through July 2013 amid concerns regarding punctuality; penalties for delayed trains increased from $100 to $300 in 2011. Although the MBTA considered operating services directly ("public option") in 2012, it ultimately declined. In August 2012, both MBCR and Keolis submitted bids for the contract; Keolis won an eight-year agreement valued at $2.68 billion with potential extensions up to $4.3 billion, assuming operations in July 2014. Keolis reported a $29.3 million loss during its initial year of operation. The contract was extended through at least 2025 as of June 2020.

In January 2008, free Wi-Fi was introduced on the Worcester Line—the first such service on a U.S. commuter rail—using routers installed on 45 coaches connecting via cellular networks. Following its success, plans were made to equip all trains with Wi-Fi by mid-2009. A private firm was contracted in 2014 to develop a new network by 2016 based on a two-tier fee structure; however, this $140 million initiative was canceled in August 2017 due to community opposition concerning monopole antennas and prioritization of other projects like the Green Line Extension. By that time, much of the original system had become largely unusable following the shutdown of 3G networks. Mobile ticketing launched on northside lines in November 2012 and expanded to southside lines later that month.

Federal mandates required Positive Train Control (PTC) implementation by the end of 2018 with possible extensions; construction began in 2017. The inner Worcester Line was the last segment to activate PTC on August 15, 2020. Most southside lines already featured cab signals enabling automatic train control (ATC), completed by 2020; northside lines lacked these systems until PTC installation concluded in January 2025. Temporary bus substitutions occurred intermittently between 2017 and 2022 during PTC/ATC installation work.

Notable milestones include:

  • Opening of the Greenbush Line in 2007.
  • The Riverside-Framingham segment was acquired by MBTA in 1976; CSX sold Framingham-Worcester tracks along with others for $100 million in September 2009 to facilitate service improvements on Framingham/Worcester lines and support the South Coast Rail project; ownership transferred in October 2012 with subsequent service enhancements.
  • As part of Big Dig mitigation efforts, stations were rebuilt and four new stops added on the Fairmount Line: Talbot Avenue (opened November 2012), Newmarket and Four Corners/Geneva (July 2013), and Blue Hill Avenue (February 2019 after delays).
  • The Providence/Stoughton Line extended southward to T.F. Green Airport (December 2010) and Wickford Junction (April 2012)—marking Rhode Island’s first commuter rail service beyond Providence since 1981.
  • The CapeFLYER summer weekend service launched in 2013 from South Station to Hyannis—the first direct Boston-Cape Cod connection since 1959—utilizing MBTA equipment under Cape Cod Regional Transit Authority branding.
  • On September 30, 2016, Fitchburg Line service was extended four miles westward to Wachusett station.

Impact of the COVID-19 Pandemic

On March 17, 2020, weekday service was significantly curtailed as a result of decreased ridership caused by the COVID-19 pandemic. By June 22, 2020, service levels had recovered to approximately 85% of their usual capacity. Adjustments implemented on November 2 reduced peak-hour operations while enhancing off-peak frequencies; concurrently, the Foxboro pilot program was put on hold.

In November 2020, the MBTA proposed shutting down six stations with low usage as part of pandemic-related budget reductions. The Board approved a limited range of cuts on December 14, including the indefinite closure of five stations. Reduced schedules commenced that same day, leaving four stations unserved.

The service reductions authorized in December took effect on January 23, 2021, resulting in the suspension of weekend service across seven lines. On April 5, further modifications increased midday service to support a transition toward a regional rail framework. Weekend operations resumed on July 3, 2021. Ridership plummeted during the pandemic, dropping to around 12,800 daily boardings in early 2021 before rebounding to 47,100 in the first quarter of 2022 and reaching 85,000 (approximately 69% of pre-pandemic levels from 2018) by October 2022. Limited Foxboro service restarted in May 2022; the full pilot resumed in September and was made permanent on October 2, 2023.

In April 2024, the MBTA extended Keolis’ operating contract for an additional year through June 30, 2027. Silver Hill station reopened on November 18, 2024. The MBTA has indicated that upcoming contracts may be segmented into distinct agreements covering train maintenance, infrastructure upkeep, operations, and dispatching.

The South Coast Rail initiative aims to expand service to Taunton, Fall River, and New Bedford. Initial planning began in 1990 but was halted in 2002; it recommenced in 2007 with environmental approvals finalized by August 2013. Due to rising costs, the project was divided into two phases in 2017. Phase I construction (2020–2024) extends diesel-powered service along the Middleborough/Lakeville Line via the Middleboro Secondary. Service officially started on March 24, 2025.

Rolling Stock

MBTA commuter rail trains operate as push-pull train configurations powered by diesel locomotives paired with a cab car at the opposite end. Locomotives are generally oriented away from Boston to minimize diesel exhaust exposure within North and South Station concourses. Train consists typically range from four to eight coaches—most commonly six—providing seating capacity between approximately 400 and 1,400 passengers. Weekday operations require around 62 trainsets.

The primary heavy maintenance hub is the MBTA Commuter Rail Maintenance Facility located in Somerville’s Inner Belt District; this site also serves as a midday and overnight storage location for northside routes. Southampton Street Yard and Readville Interim Layover accommodate light maintenance and layover needs. Additional layover facilities near line termini offer midday and overnight storage capacities. Some maintenance and storage functions are contracted out to Seaview Transportation Company in North Kingstown, Rhode Island.

Several new yard facilities are either underway or planned for future development. Two layover yards supporting South Coast Rail are anticipated by mid-2025; relocation of the Haverhill Line layover at is proposed for later in the decade. A midday layover yard at the former Beacon Park Yard site is planned by 2032 as part of I-90 realignment efforts. A substantial midday and overnight yard at Widett Circle, close to South Station, is planned to facilitate expanded operations including regional rail and electrification. Additionally, from 2023 through 2028, the MBTA intends to build a southside maintenance and layover facility at , replacing the existing yard due to closure of the Grand Junction Branch during the I-90 project.

Locomotive fleet

By October 2024, the MBTA's locomotive inventory comprised 109 units, with 87 actively deployed for passenger operations. Of the remainder, eleven were in the process of being rebuilt, six awaited repairs, and five had been retired or were out of service. Every passenger locomotive is equipped with head end power. Since 2017, a total of 37 F40PH-2C and F40PHM-2C locomotives have undergone upgrades to the F40PH-3C specification by MotivePower (MPI), alongside additional older units refurbished either by MPI or internally.

Coach fleet

As of October 2024, the MBTA possessed a total of 552 passenger coaches: 448 were operational, three were under repair or overhaul, and 101 were held in storage pending disposition or potential reuse. Coaches classified as BTC (Blind Trailer Coach) are standard cars without controls, while CTC (Control Trailer Coach) refers to cab car configurations. Single-level coaches built before 1990 offer seating capacities ranging from 88 to 127, whereas more recent bilevel models accommodate between 173 and 185 passengers. Certain cars are fitted with electronic doors tailored for routes featuring full-length high-level platforms. Restroom facilities are included in all BTC-3, CTC-3, BTC-4C, and BTC-4D coaches.

The Fitchburg Line operates a seasonal Ski Train utilizing coaches outfitted for transporting bicycles and skis. Additionally, three modified coaches function on the CapeFLYER service as bike and café cars.

In September 2019, MBTA awarded Hyundai Rotem a contract valued at $279 million (totaling $345 million) to supply 80 bilevel coaches, later expanded to 83 units including 43 cab cars. The initial four coaches arrived in June 2022 and entered revenue service in 2023. By May 2024, MBTA exercised an option to procure an additional 41 trailer cars for $203 million, with deliveries anticipated to commence mid-2026. In November 2024, a $165 million option was activated for another 39 coaches (29 trailers and 10 cab cars), facilitating the phase-out of all remaining single-level equipment; these deliveries are scheduled to begin in 2027.

Retired equipment

When the MBTA assumed control of commuter rail services in the 1970s, it inherited a varied fleet from previous railroad operators. The 1976 acquisition of Boston and Maine (B&M) and Penn Central assets brought in 94 Budd Rail Diesel Cars (RDCs)—86 from B&M and eight from Penn Central—alongside 116 coaches from Penn Central and 25 diesel locomotives, including EMD E8 and GP9 models. Although some new rolling stock was procured between 1978 and 1980, significant investments in locomotives and coaches were primarily made during the late 1980s. Until then, the MBTA depended largely on secondhand and leased equipment, such as:

By 1989, most of the inherited and leased equipment had been phased out. A notable example includes thirty-three former B&M RDCs that were converted into locomotive-hauled coaches (BTC-2 and CTC-2) in the early 1980s but retired before the decade ended. Since then, MBTA commuter rail operations have predominantly utilized locomotives and coaches newly purchased by the agency. Occasionally, temporary locomotive leases have been arranged to meet operational demands.

Certain MBTA-owned passenger vehicles have also been withdrawn from service:

  • Eighteen EMD F40PH locomotives (numbered 1000–1017), constructed between 1978 and 1980, with their final operation occurring in 2015
  • Nineteen EMD FP10 locomotives (numbers 1100–1114 and 1150–1153), rebuilt in 1979 from Gulf, Mobile and Ohio Railroad units, last used in service in 1991

Capital projects

The MBTA is actively advancing several improvement initiatives currently at different stages of planning, funding, or construction.

Regional Rail Modernization Program

The Regional Rail Modernization Program represents a multi-phase effort by the MBTA to overhaul the commuter rail system by transitioning from diesel-powered, peak-only service to an electrified regional rail network offering frequent all-day operations. Officially launched in early 2025 after extensive preparation, initial phases focus on near-term enhancements to existing diesel services.

This regional rail concept evolved following the cancellation of the Indigo Line project in 2015. Between 2018 and 2019, the MBTA conducted its Rail Vision study, which assessed various options inspired by both domestic and international transit models. In 2019, the now-disbanded Fiscal and Management Control Board formally endorsed the plan and engaged Network Rail Consulting for expert guidance.

Despite this endorsement, progress slowed into the early 2020s, with several pilot electrification projects being canceled. By 2022, rising expenses prompted a strategic shift toward utilizing battery electric multiple units (BEMUs) combined with limited catenary infrastructure as a cost-effective alternative. In early 2024, a public-private partnership approach was adopted for upcoming projects.

In July 2024, the MBTA approved a $54 million pilot program with Keolis to electrify the Fairmount Line using BEMUs, aiming for service intervals of approximately twenty minutes by 2028. As of 2025, improvements on other lines concentrate on upgrading diesel operations—including adding new turnback tracks, replacing track segments, and increasing frequency—with full electrification planned for subsequent phases.

Station upgrades

Numerous station improvement projects emphasizing accessibility, enhanced service capacity, and infrastructure repairs are either in progress or scheduled:

  • The accessible platforms at Natick Center station became operational in July 2025, with some construction activities still ongoing.
  • A newly constructed island platform at Worcester Union Station opened on July 1, 2024; the entire project is anticipated to be finalized by August 2025.
  • The design phase for reconstructing South Attleboro station to improve accessibility was completed in April 2022, although funding for construction has not yet been secured. The station was shut down in February 2021 due to structural concerns; limited service resumed in May 2024.
  • Following a temporary closure in October 2022, reconstruction plans are underway for , with temporary platforms inaugurated in December 2023.
  • Accessibility and capacity enhancement projects are planned for , , and stations. In November 2024, the state confirmed its commitment to rebuild Newtonville station.
  • In 2024, the MBTA trialed temporary freestanding accessible platforms at Beverly Depot as a cost-effective interim solution to improve accessibility without full platform reconstruction. Construction of interim platforms at four stations commenced in 2024 and was completed by 2025. An additional eight stations, including , , , , and , are scheduled for similar upgrades.
  • Ahead of the 2026 World Cup, plans are in place to reconstruct Foxboro to handle increased passenger volumes.

Past proposals

These initiatives stem from earlier expansion and enhancement studies along with various service proposals; however, none have received official MBTA approval.

Extension evaluations

During the 2020s, two potential line extensions have been examined:

  • The Middleborough/Lakeville Line extension toward Buzzards Bay or Sagamore (both located in Bourne) aimed at serving Cape Cod was analyzed in both 1997 and 2007. This proposal followed the 2013 launch of the CapeFLYER service. Bourne became part of the MBTA district in 2015. MassDOT proposed a commuter rail pilot in October 2015 involving shuttle trains between Bourne and , operated by Massachusetts Coastal Railroad, but this plan was rejected by the MBTA Fiscal Management and Control Board in April 2016. The Middleborough station, which opened in 2025 with South Coast Rail service, includes provisions for a future shuttle platform. A study conducted in 2021 projected daily boardings of 1,710 for a Middleborough–Buzzards Bay shuttle offering seven round trips, and 2,540 for a Middleborough–Bourne service with ten round trips including two off-peak Boston–Bourne trips.
  • An extension of the Lowell Line to reach Manchester and Nashua, New Hampshire has been under consideration since a pilot service during 1980–81. This extension remains politically contentious within New Hampshire, with Democratic support contrasted by Republican opposition. A 2014 alternatives analysis recommended further exploration of commuter rail options to Nashua or Manchester or intercity rail to Concord. Engineering and design work for commuter service to Manchester commenced in late 2020 and concluded by February 2023. In August 2023, gubernatorial candidate Joyce Craig publicly expressed support for the project.

Additional extensions and restorations studied include:

Infill stations

Plans include the addition of several infill stations along current rail lines:

North–South Rail Link

At present, there is no direct rail connection between the two main downtown commuter rail terminals; travelers must switch via the MBTA subway or alternate transportation methods. The proposed North–South Rail Link aims to construct a tunnel beneath downtown Boston, allowing continuous through-service with underground stops at South Station, North Station, and potentially a new Central Station. A feasibility study conducted in 2018 assessed this initiative.
