DC Transit Authority

The DCTA was the agency that managed the D.C. metro system before the Great War. The remnants of the D.C. Transport Authority can be seen around the metro (the stations, rails, cars), and the acronym DCTA can be seen on the terminals that operate the metro protectrons. Also, the downloadable metro map for the Pip-Boy is called the DCTA Map.

The DCTA had been powerful before the War because of how big and well-promoted the metro system was. All that was reduced to rubble when the bombs fell; by 2277 the stations and tunnels were largely destroyed and overrun by raiders, super mutants, feral ghouls and other unpleasant "surprises". The gates to the stations also say "Keep out by the DC transit authority", meaning they had been shut down prior to the Great War.
