The Baltimore and Philadelphia Railroad was a railroad line built by the Baltimore and Ohio Railroad (B&O) from Philadelphia, Pennsylvania, to the Maryland-Delaware state line, where it connected with the B&O's Philadelphia Branch to reach Baltimore, Maryland. It was built in the 1880s after the B&O lost access to its previous route to Philadelphia, the Philadelphia, Wilmington and Baltimore Railroad (PW&B). The cost of building the new route, especially the Howard Street Tunnel on the connecting Baltimore Belt Line, led to the B&O's first bankruptcy. Today, the line is used by CSX Transportation for freight trains.

The Wilmington and Northern Railroad is a railway company that once owned a line from Reading, Pennsylvania to Wilmington, Delaware. The original main line from Wilmington to Birdsboro, Pennsylvania was built between 1869 and 1871 by its predecessor, the Wilmington and Reading Railroad. An extension from Birdsboro to High's Junction was completed in 1874. There the Wilmington and Reading connected with the Berks County Railroad and ran over its tracks to Reading. The Berks County Railroad was foreclosed on at the end of 1874 and reorganized as the Reading and Lehigh Railroad, under the control of the Philadelphia and Reading Rail Road. The Wilmington and Reading also experienced financial difficulties and was itself foreclosed on in 1876. It was reorganized in 1877 as the Wilmington and Northern. After the reorganization, the railroad was closely affiliated with the Reading, but retained its own organization and officers until 1898. In that year, the Reading bought a majority of the company's stock and incorporated it into its own system. The main line from Birdsboro to Wilmington became the Wilmington and Northern Branch, while the extension above Birdsboro was incorporated into the Reading Belt Line. The Wilmington and Northern continued to exist as a paper railroad within the Reading system. The portion of the Wilmington and Northern north of Modena, Pennsylvania was sold to Conrail at its formation in 1976. The line south of Modena was retained by the Wilmington and Northern, which leased and then sold it piecemeal to other railroads between 1981 and 2005. As of 2021, the Wilmington and Northern still survived as a subsidiary of Reading International, Inc.
