Heljan have revealed factory decorated samples for their new run of Centre Headcode Class 37/0 diesel locomotives in O Gauge!
A whopping eight variations are to be released in 2025 catering for BR blue, large logo blue, Railfreight, BR general grey, Intercity, West Coast Railways and Network Rail liveries. These models span the decades from the 1980s to the present day, so there's something for everyone - and lots of potential for more liveries in the future.
For the first time, this version of the Class 37/0 will be offered in post-1970s form with cutaway bufferbeam cowlings, cast or fabricated bogies and a choice of nose end details, including WR headboard brackets, HI headlights and plated headcode panels. The models also feature an upgraded body with finer detail, up to eight separately controlled lighting functions, heavy duty twin motor/flywheel drive, XL pin 'plug and play' DCC decoder interface, powered roof fan, sprung buffers and couplings, wire handrails and much more.
Factory decorated samples have been revealed now for the entire range. Please be aware that these are pre-production samples and not 100% representative of the final product (for example, the lenses in the headcode panel marker lights will be corrected from clear glazing to white before production).

Prototype Information

The Class 37 (aka English Electric Type 3) were produced as part of British Rail’s modernisation plan. They became a very familiar sight across the network, in particular forming the main motive power for InterCity services in East Anglia and Scotland and performed well on other secondary routes and regional services for many years. Despite being over 50 years old, the class are still in use to this day - with over 60 in active use on passenger, freight and departmental duties as well as 30 preserved examples.
