The Massachusetts Bay Transportation Authority (MBTA) board of directors recently approved a $54 million plan to bring battery-electric train service to the Fairmount Commuter Rail Line.
The line would use battery-electric multiple unit trains (BEMUs). BEMU trains use hybrid power with an onboard battery that charges through overhead catenary wires. They also can operate on battery power.
BEMU trains provide many benefits include quieter service, lower greenhouse gas emissions, reduced energy consumption, significantly reduced noise and vibration, and a smoother ride.
“This is an exciting moment for the Fairmount Line and the communities that we serve as we utilize new battery electric technology to bring about transformational upgrades that will have long lasting benefit for generations to come,” MBTA General Manager Phillip Eng said. “Understanding that billions of dollars are needed to fully electrify our entire system, we are proud to find a way to bring electrification to this corridor sooner within available fund sources. This work will help inform us as we strive to improve and decarbonize our service on all of our regional rail network.”
Approval means the MBTA and French-based Keolis, a public transport operator, can finalize the details of their contract. Keolis will manage the fleet, additional power and charging infrastructure, and a maintenance facility.
