The Green Line is a semi-metro system run by the Massachusetts Bay Transportation Authority (MBTA) in the Boston, Massachusetts, metropolitan area. It is the oldest MBTA subway line, and with tunnel sections dating from 1897, the oldest subway in North America. It runs underground through downtown Boston, and on the surface into inner suburbs via six branches on radial boulevards and grade-separated alignments. With an average daily weekday ridership of 101,000 in 2023, it is among the most heavily used light rail systems in the country. The line was assigned the green color in 1967 during a systemwide rebranding because several branches pass through sections of the Emerald Necklace of Boston.
The Ashmont–Mattapan High-Speed Line, commonly referred to as the Mattapan Trolley, is a partially grade-separated light rail line which forms part of the MBTA's Red Line rapid transit line.

Passengers must transfer at Ashmont to access the rest of the Red Line, which uses heavy rail metro rolling stock.
The Massachusetts Bay Transportation Authority (MBTA) system is mostly but not fully accessible. Like most American mass transit systems, much of the MBTA subway and commuter rail were built before wheelchair access became a requirement under the Americans with Disabilities Act of 1990. The MBTA has renovated most stations to be compliant with the ADA, and all stations built since 1990 are accessible. The MBTA also has a paratransit program, The Ride, which provides accessible vehicles to transport passengers who cannot use the fixed-route system.

The US Standard Light Rail Vehicle (SLRV) was a light rail vehicle (LRV) built by Boeing Vertol in the 1970s. The Urban Mass Transportation Administration (UMTA) of the United States Department of Transportation (USDOT) promoted it as a standardized vehicle for U.S. cities. Part of a series of defense conversion projects in the waning days of the Vietnam War, the SLRV was seen as both a replacement for older PCC streetcars in many cities and as a catalyst for cities to construct new light rail systems. The US SLRV was marketed as and is popularly known as the Boeing LRV or SLRV, and should not be confused with their prior lunar roving vehicles for NASA.

On May 28, 2008, shortly before 6 p.m., two westbound MBTA trains collided on the Green Line D branch between Woodland and Waban stations, behind 56 Dorset Road in Newton, Massachusetts. An investigation by the National Transportation Safety Board (NTSB) originally found the cause of the accident to be due to the operator texting while driving, but the NTSB later found that the operator of the rear train, Terrese Edmonds, had not been using her cell phone at the time of the crash, but rather went into an episode of micro-sleep, causing her to lose awareness of her surroundings and miss potential hazards up ahead. The collision killed Edmonds, and numerous others were injured. Fourteen passengers were taken to area hospitals; one was airlifted. This crash, along with another similar accident a year later, led the NTSB to set higher standards and regulations regarding the use of cell phones while operating a train.
