The British Rail Class 43 (HST) is the TOPS classification used for the InterCity 125 High Speed Train (formerly Classes 253 and 254) power cars, built by British Rail Engineering Limited from 1975 to 1982, and in service in the UK since 1976.
In April 2021 RailAdventure signed a new partnership deal with Hanson & Hall Rail Services, while at the same time obtaining eight Class 43 locomotives, which will operate back to back to operate domestic services.
RailAdventure, who are based in Munich, have been involved in delivering new trains from Europe to the UK, for some time and the Class 43 units will be used to continue this service.
