MEDFORD, Mass. – The Massachusetts Bay Transportation Authority has put one of its new rapid transit trains back into service after putting the equipment on hold following a derailment in March.
WCVB-TV reports The Orange Line train built by a Chinese subsidiary of CRRC at a facility in Springfield, Mass., was returned to service on Friday after the MBTA and the State Department of Utilities agreed to changes to the oar. The changes resolve an issue that contributed to the derailment of one of the trains on March 16 as it changed lanes at Medford station.
An investigation found that problems with a switch played a role in the derailment, but also indicated that the rotational force of the trucks exceeded design limits due to issues with one component, the side support pads.

The train is part of an order for 402 cars to equip the orange and red lines of the MBTA. Five trainsets on both lines have been suspended from service since the derailment.
