B&O Old Main Line Tour
The OML is the route of the first commercial railroad in the USA as it pushed
west from Baltimore, Maryland to the Ohio River.
It was constructed largely by hand between 1828 and 1835, and amazingly, continues
in use even now by CSX.
B&O Washington Branch Tour
The B&O Washington Branch (now CSX Capital Subdivision) splits from the
Old Main Line in Relay and extends to Washington, DC.
It was built around 1835, but contains fewer surviving relics than the OML.
The route is busier and less scenic.
B&O Metropolitan Branch Tour
The B&O Metropolitan Branch, now CSX Metropolitan Subdivision, starts in Washington, DC and progresses northwest
to Weverton, MD. This tour continues to Harpers Ferry, WV as the Cumberland Subdivision.

Pennsylvania Railroad in Maryland
