Tooling

Announced in 2021 and delivered from late 2023, Heljan’s British Rail Class 73 electro-diesel locomotive for O gauge represents a major milestone in ready-to-run 7mm scale modelling. The Class 73 was a unique Southern Region design capable of operating on 750V DC third-rail electric power and via a 600hp diesel engine, making it highly versatile for passenger, freight, and engineering duties. Heljan’s model covers the production ‘JB’ batch built between 1965–67, which remains iconic on the UK network and heritage lines.

Industry reviews have praised the model as Heljan’s most detailed O gauge locomotive to date, highlighting its exceptional finish, authentic variations, and innovative features such as animated arc flashes and powered roof fan. BRM and Hornby Magazine noted its benchmark-setting quality for British outline O gauge. Social media discussions on platforms like Modern Image O Gauge have been positive, with enthusiasts impressed by the fidelity and operational performance, though some noted the need for suitable coaching stock for authentic Southern Region scenes.

Detailing: Highly detailed body with over 550 separate parts, etched metal grilles, wire handrails, and separately fitted bufferbeam details. Interchangeable headcode panels, optional arc shields, retractable collector shoes, sprung buffers, and fully functional drophead buckeye couplers. DCC-controlled third-rail arc flash effect.

Class & Prototype

  • Running Number: 73108

The British Rail Class 73 electro-diesel represents one of Britain's most versatile and longest-serving locomotive classes, designed in the early 1960s to solve the Southern Region's third-rail gap problem in goods yards. With dual 1,600hp electric and 600hp diesel modes (1,600hp diesel in Class 73/9 rebuilds), these Bo-Bo locomotives served prestigious duties from Gatwick Express to Venice Simplon Orient Express, and now operate Caledonian Sleeper services in Scotland. Of 49 built (6 Class 73/0, 43 Class 73/1), 39 survive with approximately 22 still operational, making them among British Rail's most enduring designs spanning over 60 years of continuous service.
