When a train arrives at a station, the conductor opens the doors using cab controls. Two sets of controls are provided on each side of the cab for this purpose. There are two door zones: One set of controls operates the doors in the conductor's car and the doors forward of that car, and the other set of controls operates the doors to the rear ...
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 ...

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 ...

On most systems, the conductor rail is placed on the sleeper ends outside the running rails, but in some systems a central conductor rail is used. The conductor rail is supported on ceramic insulators (known as "pots"), at top contact or insulated brackets, at bottom contact, typically at intervals of around 10 feet (3.0 m).

The train could then proceed, and a second train could follow. In the earliest days, the second train could proceed after a designated time interval, as on double lines at the time. However, after the Armagh rail disaster of 1889, block working became mandatory. Seeing the train staff provided assurance that there could be no head-on collision.
