Massachusetts Bay Transportation Authority (MBTA) leaders recently joined Massachusetts Gov. Maura Healey, other state officials and various stakeholders to mark a $54 million plan to bring battery-electric train service to the Fairmount commuter-rail line.
In July, the MBTA's board approved a plan by Keolis to introduce battery-electric multiple unit trains (BEMUs) on the Fairmount Line. Subject to the procurement process, the first train is expected to enter service in early 2028. The trains would run every 20 minutes on weekdays.
BEMU trains use hybrid power and feature an onboard battery that charges when overhead catenary wires are available, such as at South Station. The trains then can operate on battery power.
“The Fairmount Line — from South Station to Dorchester to Mattapan to Hyde Park — will be the first commuter-rail line in Massachusetts to provide 100% electric train service," said Healey in a press release.
The Fairmount line is the MBTA's shortest commuter-rail line, with nine stations. The line is used by about 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 trains, MBTA officials 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," said MBTA General Manager Phillip Eng. "This work will help inform us as we strive to improve and decarbonize our service on all of our regional rail network.
Meanwhile, the MBTA also signed an option under an agreement with Hyundai Rotem to replace an aging fleet of rail cars across its regional system. The agreement adds 41 bi-level commuter-rail cars to a previous 83-car order. The procurement contract with Hyundai Rotem is valued at $305 million.
The new cars feature increased seating for up to 179 passengers per car, designated areas for passengers with disabilities, real-time information systems with automated announcements and message displays, and improved accessible restrooms with hands-free faucets.
“As we continue to see a strong return of our ridership on commuter rail, investing in our rolling stock allows us to not only improve service levels but provides the public with a more comfortable and reliable experience,” Eng said.
The MBTA has taken delivery of 76 new bi-level coaches, with 64 already in service. The remaining coaches are undergoing final testing and are expected to enter service by 2024's end.
