also operated local streetcar service within those towns. The company was formed in 1919 to take over the lines of the bankrupt Bay State Street Railway, which advertised itself as "the world's largest street railway system" in the 1910s. Between 1931 and 1937, EMSR replaced almost all of its streetcar routes with bus service. Only three streetcar lines were left by the end of 1937, all linking Boston to nearby towns. Stoneham–Sullivan This streetcar line ran between Sullivan Square#Elevated station and Stoneham, Massachusetts. It left Sullivan operated by a Boston Elevated Railway driver and ran via the tracks of BERy's 100 line. It continued beyond from the north end of the 100 through the Middlesex Fells on a privateright-of-way west of Fellsway West. At a stop called "Sheepfold" near Spot Pond in Middlesex Fells, the operator was replaced by an EMSR employee who drove the streetcar the rest of the way into Stoneham and alongside Main Street to the terminal at Farm Hill Station of the Boston and Maine Railroad Stoneham Branch. The line was bustituted in 1946. In 1968 the MBTA took the bus service over as the 430, and from March 1969 to the end of its service in September 1971, it was part of the 100A Reading–Sullivan via Main Street and Fellsway. Quincy routes Two Quincy routes left Fields Corner station, running to Quincy center and then splitting. One line continued to Hough's Neck, and the other to Quincy Point and the Fore River Shipyard. The lines were bustituted in 1946 and 1948 respectively. The bus routes that replaced them eventually became MBTA routes , , and /.
