Middlesex and Boston Street Railway

Streetcars last ran in 1930, and in 1972, the company's operations were merged into the Massachusetts Bay Transportation Authority (MBTA).

That company went bankrupt and a receiver was appointed May 6, 1903; the property was sold on August 15, 1907, to the newly formed Middlesex and Boston Street Railway.

The latter line did not opened until August 15, 1896; omnibuses were temporarily run between Reservoir and Lake Street.

The MBTA resumed service in January 1973 as rush hour-only route 535 Auburndale–Boston College via Commonwealth Avenue.

As at Norumbega, an amusement park was built in Lexington near the Bedford town line, to attract riders from the city.

The Waltham and Newton Street Railway was chartered on July 13, 1866, and began service on August 31, 1868.
