Baltimore and Philadelphia Railroad
The Baltimore and Philadelphia Railroad was a railroad line in the United States, built by the Baltimore and Ohio Railroad 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. 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.
History
19th century
In 1838, the B&O began service from Baltimore to Philadelphia using the new PW&B line. Connecting trackage in Baltimore ran from the B&O's Mount Clare terminal east along Pratt Street and East Falls Avenue to the PW&B's President Street Station. From there the PW&B ran east on Fleet Street and Boston Street before leaving onto its own right-of-way.In 1881, the B&O attempted to gain control of the PW&B, but lost the stock battle to the Pennsylvania Railroad, which informed the B&O that it would lose access to the PW&B line in 1884. This forced the B&O to build a new route to Philadelphia. It acquired the Delaware Western Railroad, which had a charter but no track, merged it into the Baltimore & Philadelphia in 1883, and began construction. The line was in full operation by 1886. While the line in Delaware and Pennsylvania was operated by the Baltimore and Philadelphia, the line in Maryland was operated directly by the B&O as its Philadelphia Branch.
Except at its two ends, the line was built within a few miles to the northwest of the PW&B. At the Baltimore end, the line ended in the Canton neighborhood, with a car ferry across the Patapsco River to Locust Point. At the Philadelphia end, the new line crossed the PW&B and its old alignment The Baltimore and New York Railway and Staten Island Rapid Transit Railway provided their own freight terminal, at St. George on Staten Island.
Though a surface alignment through downtown Baltimore was authorized by the Maryland legislature, the B&O instead obtained a charter for the Baltimore Belt Line to provide a completely grade-separated route. This new route entered the long Howard Street Tunnel at Camden Station, running north under downtown, and then turning east through two shorter tunnels to a junction with the Philadelphia Branch at Bay View Yard. The Baltimore Belt Line was completed in 1895, and its expenses drove the B&O to bankruptcy in 1896.
20th century
The last passenger trains ran through the tunnel and over the Baltimore and Philadelphia in 1958; since then all traffic has been freight. The route is now operated by CSX as its Philadelphia Subdivision.Branches
