Network Rail Measurement Train Drive Units
The Network Rail Measurement Train is a specialised train which operates on the UK network measuring the contact between rails, wheels and the overhead electric cables. The train is equipped with specialist equipment, cameras and lasers so that it can check, measure and calculate any potential faults or failings on the track or overhead wires at speed.

Prototype:
Originally conceived as a cheaper, more reliable alternative to the Advanced Passenger Train in the early 1970s, the British Railways Board authorised the development of a prototype High Speed Diesel Train with two locomotives designated as Class 41. These aerodynamic power cars were constructed by BREL at their Crewe Works and emerged in June and August 1972, fitted with Paxman Valenta 12RP200L engines, developing 2,250 hp.
In 1987, for trial purposes, eight of the Class 43s were converted for use as Driving Vehicles with the Class 89 and Class 91 locomotives. The power cars were fitted with buffers and Time Division Multiplex (TDM) equipment that allowed them to directly control the other locomotive. Following the delivery of Mark 4 stock, the TDM equipment was removed and the power cars reverted to their normal duties.
During the late 1990s, twenty five of the Class 43s were updated with Paxman 12VP185L engines in an attempt to reduce fuel consumption and emissions; however these proved to be less reliable in service than was hoped. The HST fleet has seen many changes to the operating companies since privatisation in 1993, but Class 43 driven sets continue to operate nationwide, courtesy of First Great Western, Virgin East Coast, East Midlands Trains, Grand Central, Cross-Country and Network Rail.
