As of August 1st, Blue, Orange and Silver line WMATA subway trains will arrive every 15 minutes on weekdays, matching service on the Green and Yellow lines. For most passengers, the wait for a train will be no longer than 5-8 minutes, as most stations are served by at least two if not all three lines.
In September, Metro expects to expand the service improvements on the Blue, Orange and Silver lines to weekends providing the same level of service, every 15 minutes, on Saturdays and Sundays. This will give workers and visitors or others attending events and activities throughout the region an even more convenient way to get around – all at the weekend fare of just $2 one-way anywhere you travel.
The increased availability of railcars will also allow Metro to continue running additional trains as needed to reduce crowding and keep trains on standby throughout the system in the event a train is taken out of service due to unexpected maintenance issues.
In addition, Metro has restored more 6000-series railcars, increasing the overall number of cars available for service. Repairs to the coupler – which connects railcars – have been completed on most of the 6000-series fleet.
Metro is working to return more 7000-series trains to service as part of a phased approach. A key component of the plan includes the use of an automatic wheel measurement system on all six lines. The system uses laser technology and imaging to measure the wheelsets in real-time as trains pass over it. The first system is in place on the Green and Yellow lines and is currently undergoing testing and validation.
