Description
Hornby R3510TTS GWR Class 43 HST 125 Train Pack – Limited Edition. Power cars 43187 and 43188 for Coach Set LA15. (with Dual HST MTU TTS sound and Mega Base Speakers by Roads and Rails)
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.
The TTS decoders in this Pack have been upgraded to the latest firmware as of December 2019.
Hornby engineers have developed a unique sound decoder that not only provides superior DCC control but also dedicated sounds associated with the locomotives that have been installed with this new sound decoder – TTS Twin Track Sound.
