The Philadelphia, Wilmington and Baltimore Railroad (PW&B), based in Philadelphia, operated from 1836 until 1902, serving Pennsylvania, Delaware, and Maryland. It was established through the 1838 consolidation of four state-chartered railroads, creating a crucial rail corridor linking Philadelphia and Baltimore. The company expanded its reach through acquisitions and leases, including routes extending down the Delmarva Peninsula.

In 1881, the PW&B was purchased by the Pennsylvania Railroad (PRR), which was then the largest railroad in the United States. PRR later integrated PW&B into the Philadelphia, Baltimore and Washington Railroad in 1902.

Today, the former PW&B right-of-way remains a key component of Amtrak's Northeast Corridor and Maryland's MARC Train commuter network. Freight services along these lines are currently operated by Norfolk Southern.

Origins in Four Railroads

The PW&B traces its roots to four railroads chartered between 1831 and 1832: Pennsylvania’s Philadelphia and Delaware Counties Rail-Road Company (P&DC); Delaware’s Wilmington and Susquehanna Rail Road Company (W&S); and Maryland’s Baltimore and Port Deposit Rail Road Company (B&PD) along with the Delaware and Maryland Rail Road Company (D&M).

These charters were designed to establish a seamless rail connection between Philadelphia and Baltimore. Pennsylvania invested $200,000 in P&DC to build southward toward Delaware. Delaware allocated $400,000 for W&S to link Wilmington with Maryland. Maryland provided $1 million for B&PD to construct northeastward along the western bank of the Susquehanna River from Baltimore, plus $3 million for D&M to extend from Port Deposit or nearby points northward into Delaware.

In 1835, W&S engaged architect William Strickland to survey the route between Wilmington and North East, Maryland, estimating that constructing this 17-mile stretch would cost approximately $233,000. That same year, B&PD began operating trains between Baltimore Harbor and its Canton neighborhood.

Investor Matthew Newkirk advocated for stronger leadership to expedite construction progress and financial collections. Following leadership transitions, Lewis Brantz was appointed president.

By 1836, P&DC had opened its initial track segment, increased its capital to $400,000, and rebranded as The Philadelphia, Wilmington and Baltimore Railroad Company. By July 4, 1837, the line was nearly complete except for a vital bridge over Philadelphia’s Schuylkill River at Gray's Ferry, which opened in 1838.

Meanwhile, D&M merged with W&S to form the Wilmington and Susquehanna Railroad Company. By mid-1837, continuous track connected Baltimore to Wilmington except for crossing the Susquehanna River at Havre de Grace via steam ferry to Perryville. During this period, several locomotives were acquired from Norris Locomotive Works.

On January 15, 1838, PW&B inaugurated service from Wilmington to Gray's Ferry near Philadelphia; passengers completed their journey into Philadelphia by omnibus.

Consolidation

The operational complexities caused by tripartite ownership of the Philadelphia-Baltimore line prompted the merger of these three state-chartered railroads on February 12, 1838, resulting in the formation of the Philadelphia, Wilmington and Baltimore Railroad Company (PW&B).

That same year marked a notable event when future abolitionist Frederick Douglass escaped slavery by boarding a PW&B train from Baltimore to Philadelphia—a testament to the railroad’s early societal impact. However, later on, the company enforced discriminatory policies requiring black passengers to have a white person sign a bond before traveling.

In December 1838, PW&B completed construction of the Newkirk Viaduct over Philadelphia’s Schuylkill River, allowing uninterrupted train travel from downtown Philadelphia to Baltimore. Until a bridge over the Susquehanna River was built in 1866, ferry service interrupted continuity. The Baltimore and Ohio Railroad (B&O) began utilizing PW&B tracks that year for routes heading northeast from Baltimore.

The Baltimore terminal for PW&B was located at President and Fleet Streets; from there, tracks extended through Canton and beyond city limits toward the Susquehanna River. In Philadelphia, service terminated at Broad Street and Prime Avenue with connections via Southwark Rail-Road to reach the Delaware River waterfront.

PW&B expanded into Delaware by acquiring the New Castle and Frenchtown Railroad in 1839. Over subsequent years it took control of connecting lines, consolidating its dominance over rail transport on the Delmarva Peninsula by 1866.

By 1839, daily mail-and-passenger trains operated between Baltimore’s Pratt Street station and Philadelphia’s Market Street depot. Leadership changes included Matthew Brooke Buckley succeeding Matthew Newkirk as president in 1842; Buckley played a role in establishing one of the first telegraph lines along the railroad.

In 1844 Samuel Morse negotiated rights for B&O’s extension to Washington D.C. using PW&B’s right-of-way—integrating telegraph communications with rail infrastructure. Edward C. Dale succeeded Buckley as president in 1846.

Between 1846 and 1849 PW&B expanded its locomotive fleet by acquiring five additional engines from Norris Works. In 1850 it enhanced its Baltimore terminal by constructing President Street Station featuring a barrel-vaulted train shed. Due to restrictions on locomotives running through Baltimore city streets at that time, passenger cars were pulled by horses between stations for onward connections.

By 1853 agreements with Camden and Amboy Railroad as well as New Jersey Railroad enabled through service extending westward from New York City via PW&B tracks.

During the Civil War period significant events took place on PW&B lines: notably in 1861 at President Street Station when the Pratt Street Riot resulted in first hostile Union volunteer casualties. Between 1863 and 1865 ten additional locomotives were ordered from Norris Works.

Completion of a bridge over the Susquehanna River in November 1866 established an uninterrupted rail connection between Philadelphia and Baltimore. To improve routing efficiency and better serve populated areas, PW&B constructed what became known as the Darby Improvement during 1872–73; older alignments were leased for freight use under long-term agreements with Philadelphia and Reading Railway.

In 1873 PW&B partnered with Pennsylvania Railroad (PRR) by granting PRR’s Baltimore and Potomac Rail Road access between Philadelphia and Baltimore—facilitating more direct service to Washington.

Further consolidation occurred in May 1877 when PW&B absorbed several smaller lines including New Castle and Frenchtown Railroad, New Castle and Wilmington Railroad, plus Southwark Rail-Road—extending its main line directly to Delaware River docks.

A competitive struggle between PRR and B&O intensified in 1880 over rights on PW&B tracks. B&O president John W. Garrett attempted to acquire control of PW&B stock but was outmaneuvered when PRR secured majority ownership first. Consequently B&O constructed an independent line connecting to Philadelphia opened in 1886 while continuing to pay PRR fees for northern access.

Between 1881 and 1891 PW&B developed multiple branch lines; in 1895 it realigned its main route near Naaman’s Creek in Delaware aiming at operational improvements. On November 1, 1891 PRR leased its Baltimore and Potomac Rail Road to PW&B.

The Elkton and Middletown Railroad was proposed as a cutoff but only partially completed; it was incorporated into Philadelphia, Baltimore and Washington Railroad by 1916.

An historian writing in 1895 summarized PW&B’s strategic role: it formed a vital north-south transportation corridor rivaling ocean shipping routes while linking major industrial centers—Washington D.C., Philadelphia, and New York City—providing indispensable commercial interchange as well as military significance critical for maintaining national rail system cohesion.

Philadelphia, Baltimore and Washington Railroad

On November 1, 1902, the Philadelphia, Wilmington and Baltimore Railroad combined with the Baltimore and Potomac Railroad to create the Philadelphia, Baltimore and Washington Railroad, thereby broadening its operational reach and market presence.
