The Massachusetts Bay Transportation Authority (MBTA) Board of Directors have approved $55 Million to be allocated towards introducing Battery Electric Multiple Unit (BEMU) trainsets to the Fairmount commuter rail line. Following the approval, the MBTA and operating partner Keolis will finalize the details of the contract. Under the current procurement process the first BEMU train is expected to enter service in early 2028.
Increased Demand For Battery Electric Trains
BEMU trains are growing in popularity in the United States. In Chicago the Metra Commuter rail placed orders with Stadler for eight BEMU powered trainsets for their branch lines. The MBTA Fairmount line is the shortest line in the network with only nine stations. This short high capacity line will be ideal for BEMU trainsets where their efficiency is best optimized. The BEMUs will use hybrid power with an onboard battery that charges when the overhead catenary wires are in use at Boston’s South Station. From there the trains will run on battery power for the duration of the route. According to the MBTA over 1.6 million gallons of fuel will be saved annually on the Fairmount line. “This plan is a major win for Fairmount Line riders and our entire state. By electrifying the Fairmount Line, we’ll deliver more frequent, reliable service while also moving Massachusetts forward on our climate goals,” said Governor Maura Healey. “I’m grateful to Secretary Tibbits-Nutt, General Manager Eng and Keolis for their visionary, innovative work to finalize this plan that will have long-term benefits on our transportation system, environment, economy and overall quality of life.” “We’re thrilled that our proposal has been approved and that we are able to partner with the MBTA to introduce decarbonized service to the Fairmount line community,” said Abdellah Chajai, GM and CEO of Keolis Commuter Services. “Battery-electric trains will transform the Fairmount Line, allowing for more frequent trips, more reliable service, and reduced carbon emissions.”
