The MBTA Green Line was delayed Friday afternoon due to power problem near the Kenmore station. Trains were replaced with shuttle buses between some stops.
An MBTA spokesperson said an operator noticed smoke coming from a signal box on the right-of-way approaching Kenmore westbound around 1:45 p.m. Crews cut the power to investigate.
Shuttle buses were brought in to replace Green Line service between Copley, Hynes, Kenmore, St Marys St, and Fenway. B line passengers can use Route 57 service from Kenmore for connections to Blandford Street and points west.
More details were not immediately available.
