Hornby is a household name and is famous as the UK’s brand leader in the model railway hobby with its high quality 00 gauge (1:76) models and accessories.

The British Rail Mark 3 is a type of passenger carriage developed in response to growing competition from airlines and the car in the 1960s. A variant of the Mark 3 became the rolling stock for the High Speed Train (HST).

Originally conceived as locomotive-hauled coaching stock, the first coaches built were for the prototype HST in 1972. Production coaches entered service between 1975 and 1988, and multiple-unit designs based on the Mark 3 bodyshell continued to be built until the early 1990s. Most of the surviving fleet of the Mark 3 and its derivatives are still in revenue service on the British railway network in 2019.
