The Columbia and Port Deposit Railroad (C&PD) was a railroad that operated in Pennsylvania and Maryland in the 19th and early 20th centuries. It operated a 34-mile long (55 km) main line between Columbia, Pennsylvania, and Port Deposit, Maryland, generally along the eastern shore of the Susquehanna River. It later acquired a branch line to Perryville, Maryland. The C&PD was subsequently purchased by the Pennsylvania Railroad (PRR) and is currently owned by Norfolk Southern Railway.
The C&PD, originally called the Washington and Maryland Line Railroad and then the Columbia and Maryland Line Railroad, was chartered in 1858. The C&PD began construction in 1866, as another rail line, a branch built by the Philadelphia, Wilmington and Baltimore Railroad (PW&B), approached Port Deposit from the southeast. The PRR, which controlled the PW&B, also purchased a controlling interest in the C&PD in 1866. The first completed section of the C&PD opened in 1868 and connected the newly built Philadelphia and Baltimore Central Railroad at Rowlandsville (4 mi (6.4 km) north of Port Deposit) to the PW&B branch line. The remainder of the line to Columbia was completed in 1877, and all facilities were leased by the PW&B.
The company was reorganized as the Columbia and Port Deposit Railway in 1890. In 1893 the C&PD purchased the Perryville branch line from PW&B, and then PW&B purchased the C&PD.
The PW&B was merged into the Philadelphia, Baltimore and Washington Railroad (PB&W) in 1902, and the C&PD was merged into the PB&W in 1916. The PRR, which controlled all of these companies, labeled the line as the Port Road Branch and electrified the branch in 1938. (The Port Road branch designation continues on the line north of Columbia, to Marysville, along the Enola Branch.)
