Hanover Subdivision

The Hanover Subdivision is a railroad line owned and operated by CSX Transportation in the U.S. states of Maryland and Pennsylvania.

[5] The WM initially built from the end of the Northern Central Railway's Green Spring Branch at Owings Mills, Maryland to Hagerstown.

In addition to servicing industries and cities in Pennsylvania, the Hanover Sub provided an alternate route between Baltimore and Hagerstown, although it was 23 miles (37 km) longer than the East Sub.

The 5.3 mile (8.5 km) line ran from Walbrook Junction, west of Fulton, to Port Covington, and was designed as the WM's Tide Subdivision.

[8] Port Covington declined in the 1970s as traffic was shifted to nearby Chessie (formerly B&O) facilities, and the terminal was completely closed by 1988.
