Greenbush Line
MBTA Commuter Rail line that connects Boston and Greenbush, Massachusetts.
The Greenbush Line is a branch of the MBTA Commuter Rail system which serves the South Shore region of Massachusetts. The 27.6-mile (44.4 km) line runs from downtown Boston, Massachusetts through the cities and towns of Quincy, Braintree, Weymouth, Hingham, Cohasset, and Scituate to the Greenbush neighborhood in southern Scituate. There are ten stations along the line. From South Station to northern Braintree, Greenbush Line service shares the Old Colony Main Line with the Fall River/New Bedford Line and Kingston Line. From Braintree to Greenbush, trains utilize the Greenbush Branch, the former South Shore Railroad line that was later incorporated into the Old Colony Railroad.
Modern passenger service on the Greenbush Line began on October 31, 2007. This service restoration, put in place as environmental mitigation for the Big Dig project, was the first passenger service on the line since 1959.
History
South Shore Railroad and Old Colony Railroad
Before passenger train service stopped in 1959, commuter trains had been using parts of the Greenbush line for over 100 years. Train service was first started by the South Shore Railroad which was chartered in March 1846 to build a branch off the Old Colony Railroad at Braintree. It opened to Cohasset on January 1, 1849, running three round trips per day with Old Colony equipment.
