The station formerly had two signal boxes to supervise the passing loop and junction between the two routes - both were however closed in 1985 when the Radio Electronic Token Block system was introduced by British Rail on the Far North Line. The system was initially worked from a control centre at the station, with the line southwards planned for inclusion in the Inverness area resignalling scheme. However, when the Inverness scheme was completed in 1988, RETB control was transferred to the new signalling centre there and one here was closed. The junction points were altered so that they were (and still are) power operated - drivers of northbound trains use a plunger on the down platform to select the correct route, whilst southbound trains trigger the correct setting by occupying track circuits on the approach to the station.
