Manufacturer description
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 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.
The 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.
When 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.
Following 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.
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 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, 25 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.
Unit number 43238 was built in February 1977 and would go on to serve BR high speed services in both the BR blue and grey livery as well as the InterCity executive guise. By 2019 the unit would find itself in service with LNER, awaiting a transition to service with the East Midlands Railway.
In preparation for this the locomotive was painted out of its LNER colour scheme and into an all over red scheme with a yellow front panel, a livery which could simply have a vinyl EMR loco added to it when the time came to transition companies. This colour led to the unit being nicknamed the 'Flying Tomato'.
Unit 43305 entered service in the winter of 1978 with BR initially in the blue and grey livery before transitioning to the InterCity livery in line with the rest of the class as BR high speed services forged an identity of its own. By the late 2010's the locomotive was in service with LNER painted in their standard livery. After transitioning to East Midlands Railway with much of the LNER fleet the locomotive is currently in storage.
Upgraded for 2023, the Hornby Class 43 pack includes lights on the front and rear, kinomatic coupling system and motorised fans in the roof on certain HSTs where the fan is visible through the roof vents. Fitted with a 5 pole motor and dual flywheels, the motor car is all-wheel drive. Both units are fitted with 21 pin DCC sockets and pre-fitted dual speakers which allow for the use of sound on DCC and offer greater control of the lights and fans.
