Boston Elevated Railway
The Boston Elevated Railway (BERy) was a precursor first to the Metropolitan Transit Authority in Massachusetts, now the Massachusetts Bay Transportation Authority, operating rapid transit, streetcars, and buses in the Boston, Massachusetts area. It was formerly known as the West End Street Railway.
The rapid transit lines have evolved into the Red, Blue, and Orange Lines. The only streetcars that remain are the various branches of the Green Line and the Ashmont-Mattapan High Speed Line; the rest have been converted to buses.
The Boston Elevated Railway operated in the following cities and towns:
- Boston and the municipalities that have been merged into it
- Newton (only to get between Boston and Watertown)
- Stoneham (only the southern bit, in the Middlesex Fells)
Additionally, streetcars from adjoining towns, run by other companies, operated over Boston Elevated Railway trackage.
Originally intended to build a short electric trolley line to Brookline, the West End Street Railway was organized in 1887. By the next year it had consolidated ownership of a number of horse-drawn streetcar lines, composing a fleet of 7816 horses and 1480 rail vehicles. As the system grew, a switch to underground pulled-cable propulsion (modeled after the San Francisco cable cars) was contemplated. After visiting Frank Sprague and witnessing the Richmond, Virginia system in action, WESR President Henry Whitney chose to deploy electric propulsion systems. A section of track was used to test the Bentley-Knight underground power line, but this was abandoned because of failures and safety concerns (especially after the electrocution of a team of horses in 1889). After competing in operational tests with the Sprague streetcar system, the Thomson-Houston company was chosen for system-wide deployment of overhead wires. The electrified rapid transit system was named an IEEE Milestone in Electrical Engineering in 2004.
The first electric trolley line built by the West End Street Railway was between Union Square, Allston and Park Square, downtown, via Harvard Street, Beacon Street, Massachusetts Avenue and Boylston Street. Trolleys first ran in 1889. The Green Line "A" Branch later served roughly the same purpose.
In the late 19th century, the electric power industry was in its infancy; the power grid as we know it today simply did not exist. The railway company constructed its own power stations; by 1897, these included distributed generation stations in downtown Boston, Allston, Cambridge (near Harvard), Dorchester, Charlestown, East Cambridge, and East Boston. By 1904, the system had 36 megawatts of generating capacity, 421 miles (678 km) of track for over 1550 street cars (mostly closed but some open), and 16 miles (26 km) of elevated track for 174 elevated cars.
The difficulty of transporting coal over land from the Port of Boston and the short range of the direct current system prevented significant expansion inland. In 1911, a large generating station was built in South Boston which produced 25 Hertz alternating current, which could be transmitted long distances at high voltage, to substations which would drop the voltage for use by trains. The system was gradually converted until completion in 1931, when 14 substations were in place. This station would operate until 1981, when the MBTA decided to purchase energy from local utility companies instead of running its own generators.
The first route of the Boston trackless trolley system was opened by BERy, on April 11, 1936. It was route 77 (later 69), Harvard – Lechmere via Cambridge Street. Trackless trolleys still run from Harvard station, but only to the west and north, not east to Lechmere since 1963.
Operations of the company were taken over by the Metropolitan Transit Authority in 1947.
