Babcock Street station serves as a light rail stop on the Massachusetts Bay Transportation Authority (MBTA) Green Line B branch. It is situated within the median of Commonwealth Avenue on the western side of the Boston University campus. This fully accessible station consists of two side platforms that flank two tracks, with entry points at both Babcock Street and Pleasant Street.

Streetcar operations along Commonwealth Avenue commenced in 1896, originally managed by the West End Street Railway. Over time, the line underwent several operator transitions before becoming known as the Green Line B branch during the 1960s. Initially, stops were located at Alcorn Street—later shifted eastward to Babcock Street around 1975—and at Pleasant Street. Efforts to merge these stops into a single accessible station began in 2014. Construction for Babcock Street and the nearby Amory Street station started in February 2021, with both stations opening on November 15, 2021.

Station layout

Positioned in the median of Commonwealth Avenue between Harry Agganis Way and Babcock Street, Babcock Street station lies adjacent to Boston University's West Campus. The station features two accessible side platforms, each approximately -long, serving the pair of tracks on the B branch. These platforms occupy the center portion of a -long block and are connected by walkways leading to both bordering streets. Each platform is outfitted with -long canopies characterized by distinctive wavy colored panels.

Streetcar service

In the mid-1890s, the West End Street Railway introduced a streetcar route running through the median of Commonwealth Avenue. Service officially started on May 18, 1896, operating between Governors Square and . Later that year, the line extended service to Nonantum Square, and on November 8, 1897, it began utilizing the Tremont Street subway. The Boston Elevated Railway (BERy) assumed lease control of West End Street Railway on October 1, 1897, continuing expansion efforts. By May 26, 1900, new tracks had been laid on Commonwealth Avenue stretching from Chestnut Hill Avenue to Brighton Avenue, facilitating direct travel from Lake Street into downtown. The Nonantum Square line was further extended to Watertown Yard in 1912, establishing a service pattern that persisted for many years.

Braves Field, which opened on August 18, 1915, featured a loop track situated between Gaffney and Babcock Streets that included a prepayment station allowing direct streetcar access. This loop also accommodated Fenway Park events and rush-hour short-turn trips; after 1945, these short-turns operated during midday and Saturdays. During the 1948 World Series, streetcars ran at intervals as short as every 45 seconds between Park Street and Braves Field. In 1953, Boston University acquired Braves Field; following community requests, the loop was decommissioned on January 15, 1962. A transfer station initially proposed near Braves Field in 1921 was relocated westward to in 1922 but ultimately was never constructed.

The BERy was replaced by the Metropolitan Transit Authority (MTA) in 1947; subsequently, the MBTA took over operations in 1964. In 1965, remaining streetcar lines were consolidated under the MBTA's Green Line branding; by 1967, the Watertown route became known as the Green Line A branch, while Lake Street was designated as the B branch. The A branch service ended on June 21, 1969, leaving only the B branch operating along Commonwealth Avenue. By 1972, modest platform stops were present at Alcorn Street and Pleasant Street. Around 1975, the Alcorn Street stop was moved eastward to Babcock Street.

Station consolidation project

In 2014, the MBTA proposed merging four stops lacking accessibility near Boston University's West Campus—Boston University West, Saint Paul Street, Pleasant Street, and Babcock Street—into two fully accessible stations as part of enhancements along Commonwealth Avenue. The Pleasant Street and Babcock Street stops were combined into a single station located between the two original sites. Progress was hindered by concurrent road construction activities on Commonwealth Avenue.

On March 23, 2020, the MBTA awarded a construction contract valued at $17.8 million, with work planned from February 2021 through early 2022, including night and weekend bus substitutions throughout much of 2021. In February 2021, it was announced that the consolidated station would keep the name Babcock Street. Construction commenced following the permanent closure of Pleasant Street station on February 26, 2021. During April to June 2021, rail service between Washington Street and Kenmore was replaced by buses to accommodate platform and canopy installation. On July 30, 2021, a collision involving two westbound trains occurred near the station under construction, resulting in 25 injuries.

The original Babcock Street station ceased operations after service on November 12, 2021. The newly consolidated Babcock Street station opened on November 15, with the old station promptly dismantled.
