Class 43 (HST) spotting guide
The Class 43 is the power car at each end of the InterCity 125, or High Speed Train (HST) - one of the most successful and best-loved trains Britain ever built. For decades it raced along the East Coast, Great Western and cross-country routes, and it still holds the world record for the fastest diesel train. Though largely retired from front-line service, survivors remain a prized catch.
About the Class 43 (HST)
The Class 43 is a diesel-electric power car built by BREL between 1975 and 1982; 197 were constructed. In normal service a power car sits at each end of a rake of Mark 3 carriages to form a High Speed Train capable of 125 mph. The design transformed inter-city travel and remained in front-line use for an exceptionally long career.
History
Introduced as the InterCity 125, the HST set a new standard for fast, comfortable rail travel and in 1987 set the diesel world speed record of 148 mph. HSTs served the East Coast, Great Western, Midland and cross-country routes for many years. As newer bi-mode and electric fleets arrived, most were withdrawn, though some continued in shorter formations and other roles.
How to identify it
Look for the distinctive streamlined power car at each end of a High Speed Train, with its unmistakable wedge-shaped nose. Power cars are numbered in the 43xxx series. Note the running number of each power car to log it individually.
Fleet numbers
Numbered in the 43xxx series (197 power cars were built). Many are now withdrawn or preserved; some have run in shorter formations in later years.
Operators
Typical workings
- Historic East Coast, Great Western and cross-country expresses
- Later shorter-formation and charter workings
Where to see the Class 43 (HST)
Front-line HST service has been greatly reduced. Your best chances now are advertised charters and railtours, any remaining shorter-formation services, and preserved examples at heritage railways. Following railtour operators and heritage lines is the surest way to plan a catch.
