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.
Since the 1960s, railroad distributed power technology has been dominated by one company, Harris Controls (originally Harris Corporation — Controls & Composition Division, later purchased by General Electric—the division now known as GE Transportation) who have manufactured and marketed a patented radio-control system with the trade-name of Locotrol, which is the predominant wireless DP ...
This is a list of interurban railways in North America.Elsewhere, the term was not used or did not have the same meaning. The vast majority of these systems are defunct. All were opened primarily as passenger carriers, although many survived as freight railways after passenger service ceas
A traction network or traction power network is an electricity grid for the supply of electrified rail networks. The installation of a separate traction network generally is done only if the railway in question uses alternating current (AC) with a frequency lower than that of the national grid, such as in Germany , Austria and Switzerland .
