WMATA's Orange, Silver line trains begin running at regular intervals

Trains running on the Washington Metropolitan Area Transit Authority's (WMATA) Orange and Silver lines last week resumed six-minute rush hour service following an electrical substation fire near the Stadium-Armory Station.

In the immediate aftermath of the September 2015 incident, WMATA took several steps to protect the remaining power system, including running Orange and Silver line trains every eight minutes during rush hours, agency officials said in a press release.

WMATA also limited acceleration and restricted how many trains were in the area of the Stadium-Armory.

The agency experienced a "significant drop" in on-time performance and rider satisfaction after the incident, WMATA officials said.

The restoration of normal rush-hour service follows recovery, cleanup, testing and commissioning of new equipment.

Working with the Potomac Electric Power Co., WMATA crews in late December reconnected the Stadium-Armory substation to the power grid and begin feeding electricity to the third rail.
