Abstract
The control system is of the kind in which vehicle passage is controlled by a token, and is particularly suitable for single track railways. According to the invention, such a system is electronic, and a central control and each vehicle in use in the system is provided with electronic transmitting and receiving equipment, by which an exclusive electronic token, or the like, is transmitted between the control and a designated vehicle, the arrangement being such that, only if the electronic token is issued to a vehicle, by simultaneous operation by the controller and vehicle operator, will that vehicle be authorized to proceed, said electronic token being withdrawn by the central control once the restricted section to which it relates has been traversed by said vehicle.
