QUINCY – Early-morning riders on a part of the MBTA Red Line near Quincy Center had to take shuttle buses Tuesday while crews worked to repair damage caused by an overnight derailment of construction equipment.
The equipment derailed at about 1:20 am, MBTA spokesperson Joe Pesaturo confirmed. He said the derailment damaged the third rail.
The construction equipment was re-railed by 3:45 am and repairs to the third rail were completed at about 5 am, Pesaturo said.
It was the first night of a series of scheduled overnight shutdowns on the Braintree branch of the Red Line, where the MBTA is working on tie replacement and track re-alignment work. When completed, the project will allow the transit agency to remove speed restrictions along the Braintree branch.

At 5:10 am, the MBTA tweeted that shuttle buses would replace trains on the branch between Braintree and JFK/UMass “due to the late completion of overnight maintenance work.” The message made no mention of the overnight derailment.
Pesaturo said 25 shuttle buses provided service while power was restored and tests were run. Red Line service was restored at 6:20 am

Last week, federal transportation authorities ordered the MBTA to “conduct an immediate safety stand-down” starting this weekend affecting all employees who work with disabled rail vehicles in the T’s maintenance facilities and rail yards.
Hundreds of employees are affected, the MBTA said.
The T has been plagued by a series of recent mishaps, including two instances in which trains broke loose in Braintree. In Somerville, a fire broke out on an Orange Line train, forcing passengers to flee, including one who jumped into a river.
