To serve passengers and freight, D.C. hosts 75 miles of track, 4 rail yards, 2 stations, as well as several rail bridges and viaducts. Planned and built nearly 100 years ago, much of the rail system has reached capacity, showing that future plans must be made. D.C. train ticket sales on Amtrak’s busy Northeast Corridor rank second in the nation, but funding from Congress falls far short of reaching a state of good repair or expanding service. In 2014, more than 416,000 freight carloads passed through D.C., and with an eye toward the future, CSX has invested $25 million in D.C. rail upgrades and will spend another $200 million to renew and double capacity through D.C.’s Virginia Avenue Rail Tunnel. The owners and operators at both Union Station and L’Enfant Plaza Station have proposed expansion plans that could serve D.C.’s future need.
