Abstract: A vehicle control system issues control signals to vehicles to control their movements along a route between a first location and a second location, the vehicles comprising a set of vehicles of a first type, to which the system can issue control signals at more than one location within the route, and a set of vehicles of a second type to which the system cannot issue control signals at more than one location within the route. Sending devices sense vehicles entering and leaving the route and the type of these vehicles, storage devices stores a record of the number of vehicles within the route and a record of the type of vehicle that most recently entered the route, signalling devices signal to vehicles whether they may enter the route by moving beyond the first location and control devices receives information from the storage devices and transmits signals to the signalling devices.
