Intermediary wheel slip sequence speed processing system for multiple axle railway vehicles
 An interslip sequence slip control system for multiple wheel axle units for railway vehicles including an electronic logic network for determining whether all the axles of the vehicle are slipping at the same time. A first circuit for selecting the maximum axle speed on the vehicle and a second circuit for selecting the minimum axle rate on the vehicle. A converter circuit for increasing the bit size of the maximum axle speed signal. A plurality of calculating circuits for producing a speed reference signal. An interslip sequence circuit for supplying the maximum axle speed signal to a reconversion circuit when at least one axle is not undergoing slippage and for supplying the speed reference signal to the reconversion circuit when all the axles on the vehicle are slipping.
