Quench the fire and cool things down a bit on your layout with Rapido's range of Andrew Barclay Fireless 0-4-0 steam locomotives in OO Gauge! The entire range is now available at specially discounted prices of up to 25% off RRP for a limited time only.

These striking little shunters were used at all sorts of industrial sites where a traditional steam locomotive would have been too dangerous to use. Engineered to be rugged and simple-to-use, these locos could run just about anywhere with just one crew member. These industrial oddities survived right up to the 1990s offering all sorts of opportunities to run one.

There are a whopping 11 variations in the range, in all sorts of colourful liveires that you can bring home today - choose from either DCC Ready or DCC Sound depending on your preference! But act fast as these special deals won't last for long.

As the railways established themselves as a reliable method to transport goods one problem came to the forefront – fire. Steam locos fundamentally need a heat source created from some form of fire to turn water into steam. However, this fire, alongside sparks emitted from the chimney, caused great concern in environments where munitions, fuel or other flammable materials were being moved or stored.

The solution is a locomotive that won’t spark, or have a naked flame on board. Thankfully, some bright spark had the clever idea of harnessing steam power in a large rechargeable steam reservoir, which would sit in the place of the boiler of a conventional steam locomotive. This reservoir would be filled with a mix of boiling water and steam at high pressure. As the locomotive was used the steam would be used and thus the pressure in the reservoir would drop. This in turn allowed the water to start to boil replacing the steam that had been used. With this method a locomotive could work for about 4 hours prior to recharging.

The result is a design that has a distinct lack of key features which people associate with more traditional steam locomotives, such as a smokebox and chimney, a firebox, forward-mounted cylinders and coal bunkers or tenders. Its lack of a firebox requires its cylinders to be rear-mounted both to improve efficiency and redistribute the weight of the loco, and its other missing features are simply because they are surplus to requirement.

The largest number of British-built fireless locomotives were constructed by Andrew Barclay & Co. Ltd, and an impressive 114 were built between 1913 and 1961 of varying designs, so it was only fitting that we pick the most numerous of Barclay’s prototypes, the ‘Caledonia’, to produce as the very first Ready-to-run OO Gauge British Fireless loco. These industrial oddities survived far longer than most British Railways and industrial coal-fired steam locos with many examples working into the 1980s and even into the 1990s with many examples later preserved around the country.
