WATCH: New video released by the MBTA shows the moment an explosion led to a battery failure on trains, which prompted long delays on the Red and Orange Lines.
Less than a month after they were put back in service, the new cars on the Orange Line and Red Line of the MBTA are back off the tracks.
According to the transportation agency, the battery that failed"provides low-voltage DC power, controlling the electrical equipment on the vehicle and powering lighting, signage, and communications equipment." The train manufacturer, CRRC, and the MBTA worked together to identify the cause of the problem as an out-of-range battery temperature reading, which caused the battery to"overcharge for an extended duration and fail," officials have said
A design change was made that increases airflow in the battery compartment, the agency said. Additionally, a modification to the temperature sensing circuitry"was developed, implemented, and successfully tested over the weekend." The new cars recently returned to service, and the MBTA said it was grateful to T riders for their patience while engineers worked to ensure the cars are safely and reliably performing.
