A rail vehicle has plural drive modes powered by respective power sources (e.g. overhead line, diesel, fuel cell and battery) and a train management system (TMS) 30 for issuing command signals to train equipment to implement changeovers between the drive modes. Onboard signalling equipment 31 (e.g. automatic train operation system 31’ or ECTS equipment 31”) stores predetermined track positions at which changeovers should be made and receives updated rail vehicle positions from a tracking system (e.g. GPS 34 or speed detector 33) and changeover telegrams from trackside beacons via beacon reader 32. The signalling equipment sends changeover telegrams to the TMS alerting it that the rail vehicle is at a track position at which the drive mode should change – by relaying the changeover telegrams from the beacon reader and by identifying rail vehicle positions that coincide with the predetermined track positions and using them to generate virtual changeover telegrams. Relaying beacon changeover telegrams may be prioritised. The signalling equipment of two such rail vehicles may be in two-way communication (Fig.8)
