APT-P power car test train

Due to an extended delay in the delivery of the first trailer rake from Derby C&W Works it was decided to test and commission the power cars which were sitting around at Derby, having been delivered on time from the Locomotive Works.
The Power Car test train consisted of Test Service Car 8 housed a generator and compressor (since the trailer rake carried this equipment normally) and Test Car 5 was fulfilling its normal role. The HST power car was the only traction that could run at 125 mile/h officially - well it tried. Unfortunately one PC struggled to reach 125 mile/h so eventually the original HST PCs were used back-to-back.
Once at Crewe and under the knitting the HST was turned into a DVT and traction was supplied by the APT power car
