Since the debut of “Rush Plus” in 2012, Metro’s Blue Line riders have faced longer waits for trains. Now WMATA wants to fix that, but to do it, would cut service to all the other lines (except the Red Line).

Staff from the agency are proposing the service reduction to the Riders Advisory Council this week. WAMU’s Martin di Caro broke the news of the proposal this morning.

Under the plan, the time between trains would increase from six to eight minutes on the Orange, Silver, Green, and Yellow Lines. On the Blue Line, trains would come more frequently, up from every 12 minutes to every eight. The plan would also eliminate Rush Plus Yellow Line service between Franconia and Greenbelt.

Metro spokesperson Sherry Ly told di Caro the proposed changes are an effort to rebalance trains to better meet demand. The issue is that the service cuts to the Blue Line, which Metro did to make room for the Silver Line, drastically lowered capacity on the line, and crowding has been very bad.

But the Blue/Orange/Silver subway between Rosslyn and Stadium/Armory is at capacity. The only way to add more Blue Line trains is to cut service on the Orange or Silver Lines.

WMATA is proposing to do just that. But their proposed cuts are actually deeper than necessary. Each physical track segment can carry 26 trains per hour (TPH). Currently, the east-west subway is divided at rush hour between 11 Orange TPH, 10 Silver, and 5 Blue. Metro’s proposal to change all of those lines to 8 minute headways (7.5 TPH each) only adds up to 22.5 TPH.

The cuts to the Green and Yellow Lines make little sense at all. The shared section of the Blue and Yellow Lines in Virginia currently carries 20 TPH, so an increase in Blue Line service is possible without reducing service on Yellow. And, of course, with no change required to the Yellow Line, there’s no need to reduce service on the Green Line.

One of the steepest cuts is the elimination of Rush Plus Yellow Line trains. Right now, the section of the Green/Yellow Line between Mount Vernon Square and Greenbelt hosts 15 TPH (roughly every 4 minutes). Under the proposal, that would decline to 7.5 TPH (every 8 minutes). In the growing Mid-City area, especially south of Columbia Heights, that could create crowding. Between Mount Vernon Square and L’Enfant Plaza, service levels would fall from 26 TPH to 15 TPH.

So, the service cuts are not entirely necessary to support increased Blue Line service. But Metro’s proposal will also shift railcars around. Some will go toward lengthening trains on the Blue, Silver, and Green lines until 75% of the trains are eight cars.

Overall, the change would reduce the number of cars Metro needs to run rush hour service by approximately 100. Metro’s fleet is stretched thin at the moment. The opening of the Silver Line last July increased the number of cars needed by 64. But because of delays in the production of the 7000 series, Metro had to reduce the time cars could spend getting preventative maintenance in order to operate the line.

That was never meant to be permanent, and it’s taken a toll. Cars are breaking down more frequently, and Metro recently had to drastically cut the number of eight-car trains.
