Heljan ‘O’ gauge ED CADS revealed

Heljan has revealed progress on its forthcoming Class 73/1 Electro-Diesel (ED) with release of the latest CAD drawings for this new ‘O’ gauge project.


Built in the 1960s for use on British Rail’s Southern Region, these versatile machines were designed to operate on the Region's third-rail power supply, as well as ‘off-juice’ on their 600hp diesel engine. Examples remain in regular main line use with GB Railfreight, Network Rail and Caledonian Sleeper in original and rebuilt forms.

Heljan’s new ‘O’ gauge model reflects the Class 73/1 (JB) variant introduced from the mid-1960s and will be issued in a raft of colour schemes including a selection of newly-announced unnumbered examples (see table below). 16 different ‘O’ gauge Class 73/1 EDs are planned initially.


The impressive specification includes accurate detail variations between early and late period locomotives such as high-intensity headlights, radio aerials, optional arc shields, plus sprung buffers, buckeye couplings, detailed cab interiors, extensive body detailing and much more. Heljan is also taking the opportunity to incorporate additional features such as retractable third-rail collector shoes, powered roof fan, DCC controllable third-rail ‘flash’, interchangeable headcode panels, provision for a digitally-controlled smoke unit, digital lighting functions (microswitches for DC users) and more.

Following evaluation of these CAD images, final corrections are currently being made to the drawings before the model progresses to tooling.


Prices are set at £625 each, with delivery currently anticipated during mid-2022.
