All MBTA commuter rail service is provided by push-pull trains powered by diesel locomotives with a cab car on the opposite end. The locomotive is usually on the end facing away from Boston so that diesel exhaust does not enter the passenger concourses at North Station and South Station. Trains typically have four to eight coaches (with six the most common) and seat between 400 and 1,400 passengers. Approximately 65 trainsets are needed for weekday service.

The primary heavy maintenance facility is the MBTA Commuter Rail Maintenance Facility, located in the Inner Belt District in Somerville. It is also used for midday and overnight storage of trains on the northside lines. Southampton Street Yard and the Readville Interim Layover facility are used for light maintenance and layover service. Various other layover facilities are used for midday and overnight storage; most are located near the outer ends of the lines. Some maintenance and storage of MBTA equipment is contracted out to the Seaview Transportation Company in North Kingstown, Rhode Island.

Several additional yards are under construction or planned. Two layovers are under construction for South Coast Rail, with completion planned for late 2023, and the Haverhill Line layover at  is proposed for relocation later in the 2020s. A new midday layover yard at the former Beacon Park Yard is planned to be constructed by 2032 as part of the realignment of I-90. A large midday and overnight layover yard, which would support expanded service including regional rail and electrification, is planned at Widett Circle near South Station. The MBTA also plans to construct a southside maintenance and layover facility at  in 2023–2028, replacing the existing layover yard there, as the Grand Junction Branch will be closed for several years during the I-90 project.
