Capital Subdivision

Northbound CSX train on the Capital Subdivision at St. Denis
The Thomas Viaduct, built in 1835 over the Patapsco River, was the largest bridge in the United States at that time. It still carries the Capital Subdivision today and is the world's oldest multiple arched stone railroad bridge.

The Capital Subdivision is a railroad line owned and operated by CSX Transportation in the U.S. state of Maryland and the District of Columbia. The line runs from near Baltimore, Maryland, southwest to Washington, D.C., along the former Baltimore and Ohio Rail Road (B&O) Washington Branch.[1] The subdivision's Alexandria Extension provides a connection to Virginia and points south.[2][3]
