This retooling replaced the 2003 version and introduced significant improvements in accuracy, detailing, and technology. The Class 37, an English Electric Type 3 diesel locomotive, remained a favourite among enthusiasts, and Bachmann’s new tooling aimed to set a benchmark for modern ready-to-run diesel models.

The British Rail Class 37 is one of Britain's most successful diesel locomotive designs, with 309 locomotives built 1960-1965 by English Electric. Powered by the proven 12CSVT diesel engine producing 1,750 bhp, these Co-Co diesels served for 65 years on freight, passenger, and mixed-traffic duties across the entire BR network. Known as "Tractors" for their distinctive exhaust note, Class 37s worked everything from East Anglian expresses to West Highland Line services, Welsh coal trains, and nuclear flask operations. Extensive 1980s refurbishment created specialist subclasses including 37/4 ETH passenger variants, 37/5 freight, 37/7 heavy freight, and 37/6 Nightstar variants. Approximately 60 remain in mainline service with 30 preserved. Comprehensive OO gauge models available from Bachmann, Accurascale, and Hornby; N gauge from Graham Farish; O gauge from Heljan across extensive livery ranges spanning BR green through privatisation eras.
