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.
The Green Line, operated by the MBTA, is a light rail system with an underground section in Boston.

The MRTC 3100 class or CRRC Dalian 8MLB LRV is the class of second-generation uni-directional light rail vehicles built in China by CNR Dalian, now CRRC Dalian. Since its delivery, most of the trains are still being tested and undergoing final assessments, before being used on regular services on Line 3 of the Manila Metro Rail Transit System .
The trains also usually wore wrap ads—unlike the LRTA 1200 class which wear ads as a whole trainset, the 3000 class are seen to wear wrap ads per car. Each light rail vehicle has three roof-mounted air-conditioning units manufactured by Thermo King. In total, there are nine air-conditioning units in a three-car train set.
