By the late 1990s, remote control locomotives were increasingly popular on North American railroads for switching duties in rail yards. This system allows the conductor to directly control the locomotive(s) via a wireless remote unit, as opposed to radioing commands to an engineer in the cab.
Conductors: overhead line or; conductor rail, usually a third rail to one side of the running rails. Conductor rail can be: top contact: oldest, least safe, most affected by ice, snow, rain and leaves. Protection boards are installed on most top contact systems, which increases safety and reduces these affections.
The UIC 568 standard from the International Union of Railways (UIC), describes a 13-conductor cable and connectors used for transmitting a variety of data and commands between a locomotive and passenger carriages. Examples of those commands and data is loudspeaker messages, train destination signs, and control of doors (locked/un-locked, open ...
The UK's InterCity 125 was the first passenger train to use TDM technology, introduced from 1976 to allow it to control up to eight carriages sandwiched between two Class 43 power cars. Locotrol is a product of GE Transportation that enables distributed power sending signals from the lead locomotive to the remote units via radio control.
The Brecknell Willis Low Height pantograph is one of the four standard devices in use on British railway locomotives and multiple units and is a development of the standard Brecknell Willis High Speed pantograph. The Low Height pantograph is suitable for speeds up to 160 kilometres per hour (99 mph).
Two ICE 2 trains operating in multiple-unit train control in Bielefeld, Germany. Multiple-unit train control, sometimes abbreviated to multiple-unit or MU, is a method of simultaneously controlling all the traction equipment in a train from a single location—whether it is a multiple unit comprising a number of self-powered passenger cars or a set of locomotives—with only a control signal ...
Locotrol is a product of Wabtec Corporation that permits railway locomotives to be distributed throughout the length of a train (distributed power). It is installed on more than 17,000 locomotives around the world, sending signals from the lead locomotive and via radio to the remote control locomotives .
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 ...
