BOSTON — Shuttle buses briefly replaced service on part of the Green Line on Thursday morning after a maintenance vehicle derailed overnight in downtown Boston, officials said.
A vehicle used for track maintenance derailed at Government Center, prompting about an hourlong disruption in service ahead of the height of the morning commute, the MBTA announced just after 5:45 a.m.
Buses were replacing trains between Copley and Haymarket stations but service was restored shortly after 6:30 a.m.
The MBTA recommended commuters use the Orange line for alternate service between North Station and Back Bay during the disruption.
The cause of the derailment wasn’t immediately clear.
