The invention relates to a system for reversing a train comprising a car towing a box trailer. The driver controls the curvature of the path of the reversing car with the steering wheel. A novel control system is used to prevent the trailer jack knifing in an unstable manner by steering the wheels of the trailer. This control system steers the trailer wheels so that the instant centre of the trailer is progressively moved to become identical to the instant centre of the car. This is done in such a way that the trailer wheel angles become zero when the instant centre of the trailer matches the instant centre of the car. When the two instant centres are identical, the articulation angle will remain constant, and the trailer can be reversed in a stable manner. The invention also discloses how extra wheels can be added to the trailer which have the same instant centre as the notional master trailer wheel. The invention also discloses how the instant centres of the car and trailer can be made identical when the hitch point and the notional wheel midway between the wheels of the trailer, are on the same path. The invention also discloses how the instant centres of the car and trailer can be made identical when the notional wheel midway between the rear wheels of the car and the notional wheel midway between the wheels of the trailer, are on the same path. The invention also discloses how the instant centres of the car and trailer can be made identical when the notional wheel midway between the front wheels of the car and the notional wheel midway between the wheels of the trailer, are on the same path. -- K- Ic Ca V ci (U Vt(U g i%~.
