that the T hailed as a temporary solution to the commuter rail's reliablity problems.
Well, I've learned from a reliable source (retired MBCR employee who's a friend of mine) that, at the direction of T management, the MBCR has taken all those locomotives out of service, and they will be heading back to Maryland early Saturday morning.
The reason for this - mechanical problems that made the locomotives too unreliable to operate.
Perhaps the T and MBCR should have taken heed of this statement from a 1980s ElectroMotive Division advertisement - A 40 year old rebuilt locomotive is still a 40 year old locomotive.
Ed. note: MBTA says no, not the case. See comments for the T's response.
