APT-P trailer rake test train

The first trailer rake from Derby C&W was tested and commissioned without a power car. Instead Test Service Car No:9 was converted to represent a power car. It generally ran from Derby on a circular trip to Sheffield and back each day.

The trailer rake was commissioned separately 'off the wires' with Test Service Car 9 masquerading as an APT power car

The trailer rake test train is included on the plan - 180 miles a day with a maximum speed of 80 mile/h - probably limited by the motive power
