Service was back to normal on the MBTA's Green Line after a power problem halted service between two stations late Wednesday.
The MBTA said at 10:10 p.m. that a downed overhead wire at North Station halted service between Government Center and Lechmere. Shuttle buses were deployed to transport commuters as crews worked to fix the problem.
The delays were the latest headache for T passengers.
