|4 inch scale "Caradoc" steam tractor - stock code 7432|
We've recently sold a "Caradoc" in 3 inch scale - impressed with that one at the time. This example in 4 inch scale must be twice as much fun, we had it in steam all afternoon last week and ended up burning half a sack of coal by the time we'd all had a play with it. There's some video here of Victoria running around the yard during her week's work experience with us (and a safe pair of hands she turned out to be, owning her own 4 1/2 inch Burrell already, a career in engineering planned).
Designed by John Haining, "Caradoc" is his take on what an agricultural tractor would look like had steam continued into modern times. A whimsical idea, but he brought his immense experience to the design - a professional steam engineer in his working life, he was responsible for a range of model designs including Fowler ploughing engines and the Durham & North Yorkshire traction engine - resulting in a surprisingly capable vehicle.
Steel boiler with expanded steel tubes, 125psi working pressure, feed by injector and mechanical pump. Twin cylinder double high engine, cast iron cylinders with slide valves actuated by Stephenson's gear, pole reverser in the cab. Two speed transmission with chain drive primary.
An easy to drive, biddable engine which we found free-steaming - and a lot of fun to boot. If considering a 3 inch scale engine as the first step into miniature steam, this 4 inch engine is worth considering - particularly for the larger driver, where its power and physical size make for a more comfortable driving experience.
Complete with driving seat (which doesn't make the front end go light even when I sit on it!)
