These aerodynamic power cars were constructed by British Railways Engineering Ltd at their Crewe Works and emerged in June and August 1972, fitted with Paxman Valenta 12RP200L engines, developing 2,250 hp.\u003c\/p\u003e\n\u003cp\u003eThe power cars, having initially been numbered 41001 and 41002, were later given the coaching stock numbers 43000 and 43001 for operating trials on the Eastern Region and subsequent transfer to the Western Region. Following evaluation and a change of name to High Speed Train, British Rail placed orders for similar trains for use on the Western, Eastern, Scottish and London Midland Regions.\u003c\/p\u003e\n\u003cp\u003eWhen originally built at BREL’s Crewe Works, the InterCity 125 units were considered to be diesel multiple units and allocated as Class 253 to the Western Region and Class 254 for the Eastern Region. With the introduction of Trailer Guard Second (TGS) carriages, later power cars had no guard’s equipment installed and by 1987 most power cars were simply classified as Driving Motor (DM), although they still had luggage van space, retaining a window by the luggage door on each side.\u003c\/p\u003e\n\u003cp\u003eFollowing problems with the power cars and the operational ease of removing power cars to perform scheduled maintenance, unit formations were abandoned, resulting in the Class 43 locomotive prefix being adopted. The 197 Class 43 power cars produced between 1976 and 1982 were numbered 43002 to 43198 and are officially the fastest diesel units in the world. The units have an absolute maximum speed of 148mph (238kph), which is the current world diesel traction record, set on November 1, 1987.\u003c\/p\u003e\n\u003cp\u003eIn 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 British Rail’s Mk 4 coaching stock, the TDM equipment was removed and the power cars reverted to their normal duties, retaining their buffers. 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.\u003c\/p\u003e\n\u003cp\u003eThe HST fleet has seen many changes to the Train Operating Companies since privatisation in 1993, but Class 43 driven sets continue to operate across the rail network, despite being displaced from some East Coast and West Country routes by the arrival of Hitachi’s IEP 800 units. First Great Western, East Midlands Trains, Cross-Country and Network Rail continue to operate Class 43 units and displaced units from First Great Western have been sent to Scotland, to operate under ScotRail.\u003c\/p\u003e","brand":"Hornby","offers":[{"title":"Default Title","offer_id":58597216551293,"sku":"R2705","price":350.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0419\/5696\/6563\/files\/HornbyR27051.jpg?v=1793204140","url":"https:\/\/www.chestermodelcentre.com\/products\/hornby-r2705-class-43-43080-43068-hst-power-dummy-car-twin-pack-in-grand-central-livery-dcc-sound-fitted-era-10","provider":"Chester Model Centre","version":"1.0","type":"link"}
