 In 1904 the B&O reached agreement with the Pennsylvania Railroad to access the nearby Long Bridge over the Potomac, and then proceeded to use the Georgetown Branch as a spur servicing local industries in Silver Spring, Chevy Chase, Bethesda and Georgetown.Significant engineering features on the branch include the Rock Creek Trestle in Chevy Chase, the Dalecarlia Tunnel and a through-truss bridge over the Chesapeake and Ohio Canal.CSX abandoned the Georgetown Branch in 1986, with the last train running in June 1985, and the spur is now accessible to the public as the Capital Crescent Trail.
