After hours of delays for Metro trains on the Red Line Wednesday, workers are aiming to fix a malfunction in time for rush hour Thursday morning.
Trains were single-tracking between the Twinbrook and Grosvenor-Strathmore stations until closing time Wednesday night. Metro warned riders to expect delays and crowding.
The problem is expected to be resolved early Thursday, in time for trains to run as normal, a Metro spokesman said late Wednesday.
Inbound Red Line trains were bypassing the Twinbrook and White Flint stations to reduce delays. Riders were advised to use outbound trains for those stations, according to Metro.
The track problem near the Grosvenor station also caused delays of as much as 30 minutes Wednesday morning.
