The success of this first Camborne Hill run led to the testing of the world's first steam railway locomotive at Penydarren in 1804. Trevithick subsequently  went on to build the 'Catch-Me-Who-Can' passenger train - the world's first fare-paying passenger railway near Gower St. in London in 1808.

There are no known surviving original drawings of  the 'Puffing Devil' . This model is loosely based partly on sketches and partly on the Dredging Engine in the Science Museum in Kensington which was manufactured only two years later. Also, in the interests of ease of model construction, changes have been made - so the completed model does not pretend to be an accurate scale model, but it does reflect the essence of the original engine.  
 

To build the model, the constructor will need to screw, glue, saw, drill, file and cut various small mainly brass parts. 

 The basic kit comes with a fuel tray to burn solid fuel (Esbit / Mamod Type) tablets. Because of the weight of the engine, the these tablets will provide enough heat and steam pressure to operate the engine in a stationary mode only. Stationary mode means that the drive wheels are supported clear of the ground and the engine drives the wheels without driving the model along the ground. 

The kit comprises pre-soldered brass boiler, pre-drilled and painted boiler casing, pre-finished wooden chassis and wheels, white metal castings, finished brass components,  brass strip, rod and tube, screws, nuts and bolts and fuel tray for stationary operation only (see Notes on Operation).
