Dedicated traction current lines are used when railways are supplied with low-frequency alternating current (AC). The traction current supply line is connected to substations along the line of the railway and is usually run separately from the overhead catenary wire from which the locomotives are fed.
A traction substation, traction current converter plant, rectifier station or traction power substation (TPSS) is an electrical substation that converts electric power from the form provided by the electrical power industry for public utility service to an appropriate voltage, current type and frequency to supply railways, trams (streetcars) or ...
Railway electrification as a means of traction emerged at the end of the nineteenth century, although experiments in electric rail have been traced back to the mid-nineteenth century. [1] Thomas Davenport , in Brandon, Vermont , erected a circular model railroad on which ran battery-powered locomotives (or locomotives running on battery-powered ...
Indian Railways: Entire IR network uses the current system since 2016. Mumbai: Mumbai Suburban Railway: Conversion from 1.5 kV DC to the current system was completed in 2012 (for Western line [13]) and 2016 (for Central line [14] [15] [16]) respectively Mumbai: Mumbai Metro (Line 1) Chennai (Madras) Chennai Metro: Delhi: Delhi Metro: Hyderabad ...
Railway electrification systems using alternating current (AC) at 25 kilovolts (kV) are used worldwide, especially for high-speed rail. It is usually supplied at the standard utility frequency (typically 50 or 60 Hz), which simplifies traction substations.
For traction current lines with four systems (8 conductor cables), the two-level arrangement (4 conductor cables on each crossbar) is frequently used, except for traction current lines supplying high-speed railway lines are used. For these lines a three-level arrangement is used, in which the lowest cross bar has four conductor cables and each ...
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.
A traction power station is a power station that produces only traction current, that is, electric current used for railways, trams, trolleybuses or other conveyances. Pure traction power stations are rare and there are many more power stations that generate current for other purposes, such as standard three-phase alternating current (AC), in addition to traction current.
