BOSTON (WHDH/AP) — The Massachusetts Bay Transportation Authority is investigating what caused a Green Line power problem, disrupting the Tuesday morning commute.
Service was interrupted at about 8:30 a.m. Tuesday when a wire that carries 600 volts of electricity between Arlington and Copley stations sustained damage, the MBTA said.
The T turned to shuttle buses along the affected Green Line routes, and broadcasters showed large crowds waiting for buses. The T also suggested commuters switch to the Orange Line.
Passengers on two trains had to evacuate inside tunnels and walk to stations.
One man tweeted a video of commuters getting off a trolley that lost power in a tunnel.
All service was restored by about 11 a.m.
In a statement, the MBTA said it’s making improvements.
The statement reads in part, “For the Green Line alone, more than $365 million is being invested in improvements to signals, tracks, tunnels, bridges and power systems, which include overhead wires.”
The area that was damaged had been inspected less than a week ago, the MBTA said. They apologized for the inconvenience and are looking into what caused the wire damage.
