The LightRail (Subway) in Boston, USA 2020 (Green Line)

The Green Line is a light rail system run by the Massachusetts Bay Transportation Authority (MBTA) in the Boston, Massachusetts, metropolitan area. It is the oldest Boston rapid transit line, and with tunnel sections dating from 1897, the oldest in America. It runs as a deep-level subway through downtown Boston, and on the surface into inner suburbs via four branches on several radial boulevards. With an average daily weekday ridership of 152,200 in 2019, it is the second most heavily used light rail system 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 four branches are the remnants of a large streetcar system, which began in 1856 with the Cambridge Horse Railroad and was consolidated into the Boston Elevated Railway several decades later. The branches all travel downtown through the Tremont Street subway, the oldest subway tunnel in North America. The Tremont Street subway opened its first section on September 1, 1897, to take streetcars off overcrowded downtown streets; it was extended five times over the next five decades. The streetcar system peaked in size around 1930 and was gradually replaced with trackless trolleys and buses, with cuts as late as 1985. The new D branch opened on a converted commuter rail line in 1959; the Green Line Extension project will extend two branches into Somerville and Medford, and is planned for completion in 2021 ~Wikipedia - Comment below so we can all have a productive 'conversation about transportation!'
