Posted by on

We have made substantial reductions across the range of Heljan OO Gauge Class 104 DMUs, with savings now reaching up to 37% off RRP.


These beautifully detailed models capture the character of the iconic first-generation diesel multiple units and are available in a selection of liveries and formations while stocks last.With reductions of this size, we expect the remaining stock to move quickly — so if you have been considering adding a Class 104 to your collection, now is the ideal opportunity.

This comprehensive 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.


The models feature a low profile mechanism powering one car per set, switchable interior and exterior lighting features, a 21-pin DCC decoder interface and provision for DCC sound. Options for factory-fitted DCC sound on all models are being investigated and will be announced separately. External features will include authentic detail variations appropriate to period and livery, a highly-detailed interior and underframe, separate handrails and sprung buffers.


The '104s' are among the most complex models Heljan have ever developed, with a huge range of detail variations to cab ends, roofs, interiors, body details and more.

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. 


The class were re-engineered to remove asbestos insulation in the 1970s and were eventually withdrawn by the end of 1993.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.
