APT-P Driving Trailer Second (DTS) unit, in revised APT branding, with a black "mask" around the driver's window.
APT-P Non-Driving Motor (NDM) unit, with high-speed pantograph.
British Rail 's Class 370 tilting trains , also called APT-P (meaning A dvanced P assenger T rain P rototype), were the pre-production Advanced Passenger Train units. Unlike the earlier experimental gas-turbine APT-E unit, these units were powered by 25kV AC overhead electrification and were used on the West Coast Main Line between London Euston and Glasgow Central . The APT-P is the most powerful domestic train to have operated in Britain, the eight traction motors fitted to the two central Motor Cars giving a total output of 8,000 hp . This enabled the train to set the UK rail speed record of 162.2 mph in December 1979, a record that stood for 23 years.[ 9]
