A problem with Amtrak’s signal system created headaches for Amtrak and MARC trains on Monday afternoon.
Signal problems between Washington and Trenton, N.J., began at around 2:18 p.m. and lasted until nearly 3 p.m. As a result, Amtrak trains could encounter delays of up to 40 minutes, according to Steve Kulm, a spokesman for the rail agency.
Trains didn’t lose power, so air conditioning and lights remained on for riders, Kulm said. But the signal system lets locomotive engineers receive instructions about moving along the railroad, so while it had issues trains could not move.
Service on MARC’s Penn Line was temporarily halted due to the signal failure. The Maryland Transit Administration reports that service is slowly returning to these MARC trains, but riders should watch for delays.
Amtrak and MARC trains between D.C. and New Jersey were also delayed by signal problems on Friday afternoon.
