Zusammenfassung:An axle generator assembly for a brake system for a railway vehicle comprises a two phase motor adapted to be driven from an axle end of a freight wagon. Both phases can be rectified to generate power for the brake system and the assembly further comprising frequency detection circuitry to detect the frequency of the phases. The frequency of one or both of said phases is then used to generate a speed signal. Four axle end generators 30-33 may be provided, each having two pairs of outputs corresponding to respective ones of two phases. The motor may be a stepper motor. The system is aimed at least partly at reducing damage to wheels and track, such as may occur due to wheel slide or spin.
