Based on the CargoSprinter railcar from the 1990s, Windhoff developed a modular platform for self-propelled railway service and rescue vehicles. The vehicles, known as Multi Purpose Vehicles MPV, are powered by two 6-cylinder MTU diesel power packs with a flanged ZF gearbox. The 780 kW four-axle vehicles reach a top speed of 100 km/h. From 1999, the British state infrastructure operator Network Rail procured a total of 18 single and 32 double units for work on the rail network.
F2 slows down the locomotive slowly.
F14, F18 and CV 170 value 0 or 1, can switch between a "normal announcement" or an announcement "with gong".
F9 can increase the speed of the spirax valve by double-clicking it. The speed levels are slow, medium and fast.
17 will bring the locomotive to full stop.
F21 and CV 168 = value 0 or 1, can switch between a "normal" or a "squeaking" wiper.
F28 and CV 164 = Value 0, 1, 2 or 3, can switch between different rail joints (three coupler can be activated with CV 165 = value 1).
F29 and CV 169 = value 0 or 1, can switch between the "Automatic Warning System (AWS)" or the "Train Protection and Warning System (TPWS)".
