In 1964, the Massachusetts Bay Transportation Authority (MBTA) became responsible for all public transportation in the Boston metropolitan area, first by taking over the Metropolitan Transit Authority. Several streetcar and trolleybus lines continue to operate.
In 1968, MBTA expanded significantly into the suburbs, by acquiring the Eastern Massachusetts Street Railway. And in 1972, MBTA acquired the Middlesex & Boston Street Railway.
STREET RAILWAY COMPANIES
Many individual streetcar companies were eventually consolidated into fewer larger companies, prior to the introduction of buses.
