A railway signalling system includes an ERTMS radio block centre (9) which has been overlaid on to a 5 signalling system with an existing electronic interlocking (2), there being corroborating means (10) coupled to receive safety-related control data from an interface of the interlocking and safety-critical trackside data from an interface of the interlocking and provide to the radio block centre a safety-critical version of the control data, or a version of it with increased safety integrity, using the safety-critical trackside data.
