Accurascale have let us know that their new run of OO Gauge Class 37/4 diesel locomotives are in production now and set to arrive with us during Q1 2026!
There are five new variations to choose from in this latest batch including BR large logo blue, Railfreight Sector, EWS maroon & gold and Colas Rail Freight liveries - offering you multiple eras and regions to choose from. Accurascale claim that their Class 37 tooling the most complex and extensive locomotive tooling suite anywhere in the world, simply because of the huge range of detail variations we’re covering within a single class. That level of complexity inevitably adds time during production and on top of a tweaked PCB in this new run - that has afforded a delay - but the good news is that they are nearly complete and due early in 2026.
All of these models are available to pre-order now - available either DCC Ready or DCC Sound Fitted.

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.
