RETB is a cost-effective in-cab system for signalling rural, single track rail networks
RETB (Radio Electronic Token Block) is a system of railway block signalling designed for single track rail routes with light to medium traffic density. It is a development of the physical token system, but uses a radio network to issue an electronic token directly to in-cab train equipment.
The track route is divided into block sections with a passing loop at each end:
