Radio Electronic Token Block.


Its a system developed in the 1980s to control long sections of remote railway by one control centre. The signalman issues 'tokens' remotely to drivers via radio which is displayed in the cab on a special head unit. The system is really an electronic version of ETB but intead of the driver carrying a physical token, his authority is an elcetronic token.
