Railway electrification is the development of powering trains and locomotives using electricity instead of diesel or steam power.The history of railway electrification dates back to the late 19th century when the first electric tramways were introduced in cities like Berlin, London, and New York City.
From 1928 to its abandonment in 1940, the narrow-gauge Boston, Revere Beach and Lynn Railroad was operated with overhead electrification. The railroad shut down in 1940, and portions of it were used for the MBTA Blue Line which opened in 1953, although it used an entirely new electrification system and is operated as part of a subway system.
Third-rail electrification between Hartford, New Britain, and Berlin, a total of 12 mi (20 km) in 1896. This third-rail system was unique; it consisted of an inverted V cross-section rail, mounted on the cross ties between the running rails, and was totally exposed. In 1898, the New Canaan Branch was electrified with 500V DC catenary. [1]
A general manager headed the Railway Electrification Organisation, established in Kolkata in 1959. In 1961, the Northern Railway zone electrification office (headed by an engineer-in-chief) was established in Allahabad for the electrification of the Mughalsarai–New Delhi section. Following the 1978 J. Raj Committee report, several ...
Acton Central station is a changeover point from 750 V DC third rail, to 25 kV AC overhead electrification, on the North London Line. Railway electrification in Great Britain began in the late 19th century. A range of voltages has been used, employing both overhead lines and conductor rails.
The system is also known as the Southend Electrification, in contrast to Amtrak's 60 Hz traction power system that runs between Boston and New Haven, which is known as the Northend Electrification system. In 1976, Amtrak inherited the system from Penn Central, the successor to the Pennsylvania Railroad, along with the rest of the NEC ...
Since 1940. Used both third rail DC (1200 V) and overhead line AC (6.3 kV 25 Hz) until 1955. Also uses German standard 15 kV AC 16 2/3 Hz overhead electrification on the section between Neugraben and Stade on line S3, opened in December 2007.
The Caltrain Modernization Program (CalMod), sometimes referred to as the Caltrain Electrification Project, was a $2.44 billion project which added a positive train control (PTC) system and electrified the main line of the U.S. commuter railroad Caltrain, which serves cities in the San Francisco Peninsula and Silicon Valley.
