Most suited to N Gauge.
Converts standard coupling by fitting an EM02 adaptor on the underside of the coupling hook.
Uncoupling is achieved by stopping the adaptor fitted wagon directly over the EM01. When the EM01 is energised, the steel adaptor arm is attrtacted downwards, making the coupling arm lift up to uncouple.
Requires 12 to 25v AC supply at 1.25amps
