The MBTA is reporting delays on the Kingston/Plymouth, Greenbush and Middleborough/Lakeville lines this morning after an outbound train broke down in Quincy Center.
According to Scott Farmelant, spokesman for the Massachusetts Bay Commuter Railroad Co., an outbound Kingston train broke down in Quincy Center where there is just one track serving the South Shore lines and both inbound and outbound traffic.
The disabled train has since been pushed back into Boston, but the problem has caused delays ranging from 15 minutes to more then 40 minutes for passengers on Trains 008, 036 03, 040, and 074. Farmelant said.
Farmelant said full service was expected to be restored by 9:30 a.m. The cause of the engine breakdown was not immediately known, he said.
MBCR operates the commuter rail system under a contract with the MBTA.
