The Alexandria Fourth Track project will design and construct 6.0 miles of railroad track and related infrastructure in Arlington and Alexandria, VA. The project extends between the southern end of the Long Bridge Project, adjacent to the Long Bridge Aquatic Center, to just west of Alexandria Union Station and will add one additional track to the existing three-track segment.
Currently, on the southern end of the project area, west of Alexandria Station, three tracks from the Virginia Railway Express (VRE) Fredericksburg Line and two tracks from the VRE Manassas Line converge into three tracks, causing a bottleneck and delays for passenger and freight trains. The existing tracks will be shifted, and a new fourth track will be added, all within the existing right-of-way. The results will separate freight and passenger trains and add capacity and efficiency traveling north into Arlington and Washington, DC. The design also accommodates station and platform improvements planned by VRE for the Alexandria and Crystal City passenger stations.
