The Green Line is one of the most-used light rail systems in the United States, serving over 101,000 passengers per day in 2023. [ 2 ] The state of Massachusetts committed to extending the Green Line in 1991, as part of a settlement related to the impacts of the Big Dig , but construction work on the Green Line Extension did not begin until 2012.

All of the concepts proposed a longer vehicle than the current Type 8/9 cars, with lengths ranging from 100 to 131 ft (30 to 40 m). The MBTA's final concept for the new cars was a 114-foot (35 m) articulated low-floor light rail vehicle made up of 7 segments, riding on 4 trucks, and equipped with 5 sliding doors on each side.

The renaissance of light rail in North American began in 1978 when the Canadian city of Edmonton, Alberta adopted the German Siemens-Duewag U2 system, followed three years later by ...
The SLRVs were designed to both increase passenger capacity and to improve the accessibility of DART's light rail system. [6] Each three-section, articulated SLRV measures 123.5 feet (37,643 millimeters) over couplers , while the maximum train length is four articulated cars coupled together , measuring 494 feet (150,572 mm) over couplers in ...
