Baltimore & Potomac Tunnel

The origins of the Baltimore & Potomac Tunnel begin in 1858, when Charles County planters pushed for the Baltimore & Potomac Railroad to connect their farms to markets in Baltimore. Progress remained slow until 1867, when the Pennsylvania Railroad Company bought the business.

In July 1872, the completion of the Baltimore and Potomac Tunnel (below Winchester and Wilson Streets) enabled the B&P Railroad to start service between Baltimore and Washington, DC.

In 1983, the MARC train joined the list of commuter trains that have used those same tracks, ensuring the continued popularity of the station for travelers today. In 2014, the Federal Railroad Administration (FRA), Maryland Department of Transportation (MDOT) and Amtrak are currently conducting an engineering and environmental study reviewing a range of options to modify or replace the existing tunnel.
