Willesden sidings

Set No: 370004 sits in Willesden Carriage Sidings, London after failing on a VIP test run from Euston Station. In early summer of 1980 the BR/Brecknell Willis pantograph had been installed on this set and this was one of its first runs. Needless to say the failure was unconnected with the pantograph!
Cab desk A view of the driver's desk - note the two cancellation buttons in front of the power handle. One was for the AWS and the other for C-APT

A tantalising half frame photo of set No: 370001 at Crewe next to a Class 47 in the summer of 1980. Who would have thought that the Class 47 would outlive the APT?

This was one of those Murphy's Law events when this frame happened to be the last one of the film!

Stafford APT-P leaving Stafford - seen from a passing test train - probably sometime in 1979-80 Stafford again With what appears to be one car tilted out of line - where the punters are gathered on the platform - the set departs towards London.
Power car test train formation Due to an extended delay in the delivery of the first trailer rake from Derby C&W 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.

This is the Power Car test train- 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

Once it was all together and under the wires it began to look like the real thing but it was only 2+6 cars

Here are some scans from the 1981 Scottish Region APT-P Class 370 training manual. The drawings are by David Gibbons who used to illustrate the informative centre spreads of the staff newspaper Rail News and had several books of his drawings published. From memory these drawings convey an accurate impression of the vehicles and interiors.

The 'City of Derby' nameplate from one of the power cars now resides on the wall inside the NRM.

If you have found this page related to the APT-P of interest, then perhaps you would like to look at a few other sites devoted to APT-P and also one to the original gas turbine version called APT-Experimental, which was tested at Old Dalby.

Gerry Bates also has a site with some photos of APT-P on OHLE uplift tests in Scotland in 1979.

And another site with photos of a class 40 hauling 370006 APT set on Leeds Whitehall triangle in early afternoon on Thursday 17th March 1983.
