The Baltimore and Potomac acquired this line after reaching it, operating it until 1901, when the Washington Southern Railway (the successor of the Alexandria and Washington) was taken over by the Richmond, Fredericksburg and Potomac Railroad, an independent bridge line owned equally by the PRR and five other railroads. Soon after, in 1904, the line from the Long Bridge to Rosslyn, built by the Washington Southern, was split off into the Rosslyn Connecting Railroad, owned by the PRR.

The railroad that ran past the Pentagon was the onetime Pennsylvania RR Rosslyn branch. This branch left the mainline at RO (for Rosslyn) tower at the south end of the bridge over the Potomac and basically followed the Potomac northwest to Rosslyn. Part of it was built on the bed of the old canal that connected Alexandria with the C&O Canal in Georgetown.

The most of the line follows along the route of an old disused canal and in constructing the roadbed the carrier used the canal grading as far as possible.
