The Accurascale Class 73/9 celebrates the reinvention of one of Britain’s classic locomotive families. Originally built in the 1960s as  electro-diesels for the Southern Region, the Class 73 fleet combined 600hp diesel engines with third-rail capability. From 2015, eleven locomotives were rebuilt by Wabtec at the former Brush works in Loughborough, forming the modern Class 73/9 fleet. These machines gained powerful 1600hp MTU 8V4000R43L engines, new AC alternators, upgraded cooling systems and significant structural refinements, effectively creating a “half-HST” within the classic 73 bodyshell. Comprehensive overhauls saw renewed bogies, refurbished traction motors, simplified air-only braking and the introduction of modern features such as LED lighting and CAPOS capacitor-based starting.Two distinct groups emerged and are offered in model form for the first time: Phase 1, finished in GBRf livery for southern operations, and Phase 2, adapted for Caledonian Sleeper duties in Scotland with further front-end, fuel and cab modifications.
