Heljan have given us a sneak preview at the latest decorated samples for their newly tooled OO Gauge Class 104 diesel multiple unit!
This comprehensive new range covers both the 2-car and 3-car versions of this classic first generation DMU in a wide assortment of liveries including BR green, BR blue, BR blue/grey, Network SouthEast and ScotRail 'Mexican Bean' livery. As you can see from the samples, these are shaping up very nicely indeed and we look forward to having a look at some more samples in the range soon!
We currently expect these models to arrive in stock with us during Q2/ Q3 2025. Heljan have advised that these are close to being sold out so we highly recommend you place your pre-orders now to avoid missing out!

Prototype Information

The British Rail Class 104 Diesel Multiple Units were designed for general branch line and commuter routes. The first units were ordered for the London Midland region, with most being used in the North West but others were also used in Tyneside, Scotland and London.Â
The class were re-engineered to remove asbestos insulation in the 1970s and were eventually withdrawn by the end of 1993. Several sets made their way into preservation.
