The Philadelphia, Baltimore and Washington Railroad (PB&W) was a railroad that operated in Pennsylvania, Delaware, Maryland, and the District of Columbia in the 20th century, and was a key component of the Pennsylvania Railroad (PRR) system. Its 131-mile (211 km) main line ran from Philadelphia to Washington.:228 The PB&W main line is now part of the Northeast Corridor, owned by Amtrak.
The PB&W acquired these railroad companies:
- 1906: South Chester Railroad
- 1913: Baltimore and Sparrow's Point Railroad
- 1916: Philadelphia and Baltimore Central Railroad, Columbia and Port Deposit Railway, Elkton and Middletown Railroad
- 1956: Pittsburgh, Cincinnati, Chicago and St. Louis Railroad (Pan Handle Route)
In 1928, the PRR began to electrify the main line between New York and Washington using overhead lines. Electrification of the PB&W portion was completed in 1935. Amtrak still uses the 25Hz traction power system.
In 1968, the Pennsylvania Railroad and its longtime rival New York Central Railroad merged to form the Penn Central Railroad. The PB&W remained a separate legal entity, controlled and operated by the new company. The Penn Central declared bankruptcy in 1970 but continued to operate trains until 1976, when the company's railroad assets were sold under the Railroad Revitalization and Regulatory Reform Act. Under the new law, Congress authorized the sale of the PB&W right-of-way between Philadelphia and Washington, and related assets (such as the Washington Terminal Company), to Amtrak. Other PB&W assets, including almost all of the PCC&StL (Pan Handle), were sold to the new Consolidated Rail Corporation (Conrail).:122
