Full Power Restored To Green Line

The T’s Green Line is expected to be back in operation today after a downed power line killed service for five hours through much of yesterday afternoon, the transit agency said.The line was repaired and there is no expected impact on today’s schedule, MBTA spokesman ­Joseph Pesaturo said.The wire, which provides electricity to trolley cars, came down between Park Street and Boylston stations after it became entangled in the trolley’s pantograph — the structure on the roof of the car that runs along the overhead lines, Pesaturo said.
