LOCOMOTIVE Russian patent published in 2009 - IPC B61C15/08 

FIELD: railroad transport.

SUBSTANCE: proposed locomotive comprises frame with wheel pairs fitted thereon, cabs with control board, power plant, traction drive connected with thyristor rectifiers incorporating current and voltage transducers. Traction motors are mounted on every wheel pair axle and furnished with speed pickups connected to controlled thyristor rectifiers incorporating back-biased diodes. Note that control system represents control and synch unit connected with processor. Traction motors are connected via reverser and switch with thyristor rectifier and reverser thyristor control pulse shaper. Power plant is connected via parametre control unit with data I/O device.

EFFECT: higher locomotive traction factor and ruling out wheel pair slippage.
