Remote_control_locomotive
A remote control locomotive (also called an RCL) is a railway locomotive that can be operated with a remote control. It differs from a conventional locomotive in that a remote control system has been installed in one or more locomotives within the consist, which uses either a mechanical or radio transmitter and receiver system. The locomotive is operated by a person not physically at the controls within the locomotive cab.[1] They have been in use for many years in the railroad industry, including industrial applications such as bulk material load-out, manufacturing, process and industrial switching. The systems are designed to be fail-safe so that if communication is lost the locomotive is brought to a stop automatically.[1]
