The Massachusetts Bay Transportation Authority Board of Directors has approved a $54 million plan to bring battery-electric train service to the Fairmount Line. The plan put forth by commuter rail operator Keolis is expected to result in more frequent service and lower emissions in surrounding communities.
The battery-electric multiple-unit trains will take in power from overhead wires where available (such as South Station) and then run off batteries where the wire is not available. It is anticipated that trains will run every 20 minutes on weekdays.
MBTA officials said they hope to have the first train in service on the Fairmount Line in early 2028.
“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.”
The Fairmount Commuter Rail Line is the shortest of the Commuter Rail Lines with nine stations. As of April 2024, the line carries approximately 3,200 passengers per day. Battery-electric service will save 1.6 million gallons of fuel and mitigate 17,700 tons of carbon dioxide per year compared to diesel.
