An Act relative to setting deadlines to electrify the commuter rail

This bill requires the Massachusetts Bay Transportation Authority (MBTA) to provide fully electric commuter rail service on specific lines by 2029 and across the entire system by December 31, 2035. It mandates the MBTA to develop detailed short-term, medium-term, and long-term plans for electrification, including timelines, funding needs, and infrastructure upgrades, with public comment periods required before finalizing these plans. The short-term plan must prioritize the Providence/Stoughton, Fairmount, and Boston-to-Beverly segments of the Newburyport/Rockport lines for full electrification by 2029, while also considering environmental justice areas for future expansion. The bill directly affects MBTA commuter rail operations, setting concrete deadlines for transitioning to zero-emission trains and requiring specific planning mechanisms to meet state climate goals.
