Centralized traffic control (CTC) is a form of railway signalling that originated in North America. CTC consolidates train routing decisions that were previously carried out by local signal operators or the train crews themselves.
General Railway Signal Company (GRS) was an American manufacturing company located in the Rochester, New York area. GRS was focused on railway signaling equipment, systems and services. The company was established in 1904 and became part of Alstom Transport in 1998.
Railway signalling (BE), or railroad signaling (AE), is a system used to control the movement of railway traffic. Trains move on fixed rails , making them uniquely susceptible to collision . This susceptibility is exacerbated by the enormous weight and inertia of a train, which makes it difficult to quickly stop when encountering an obstacle.
Train order traffic control was used in Canada until the late 1980s on the Algoma Central Railway and some spurs of the Canadian Pacific Railway. On CN's Deux-Montagnes commuter line, this system lasted on part of the route until the total replacement of signaling and catenary in 1995. The orders were notable for being bilingual.
Train Dispatcher is a train simulator of centralized traffic control (CTC) systems. It was originally developed in the 1980s as a training tool for a commercial railroad and was then made available to the public. The software is currently produced by SoftRail (formerly Signal Computer Consultants) for Windows-based computers.
Local dispatchers at work at the central station in Bohumín, Czech Republic, in August 2008. A train dispatcher (US), rail traffic controller (Canada), train controller (Australia), train service controller (Singapore) or signaller (UK), is employed by a railroad to direct and facilitate the movement of trains over an assigned territory, which is usually part, or all, of a railroad operating ...
Communications-based train control (CBTC) is a railway signaling system that uses telecommunications between the train and track equipment for traffic management and infrastructure control. CBTC allows a train's position to be known more accurately than with traditional signaling systems. This can make railway traffic management safer and more ...
