This is my entry for the cardboard train competition at the recent Arundel exhibition. It won joint first prize (out of a field of three!)
Anyway, the rules were to build an entire train, any scale or prototype, largely from card. I chose to model a Lister diesel rail truck and assorted Heywoods stock, from various of his railways, plus a mining tub. Marshalled together they would represent an exhibition goods train on a 15 in gauge railway.
Firstly, then, the train;
And a close-up of the Lister
Here is the unpainted Lister. The red parts are from file card. The white parts are from mounting card. For the engine and tanks I glue several layers together then carve and sand them to shape.
Knobs and filler caps are from hole punchings glued together. The gear lever and pedestals are from paper wrapped around card.
The underview shows the non card parts - a Tenshodo bogie and offcuts of G Scale track encased in card to give weight.
Lastly the lifting eyes, visible on the completed model, are punchings from mounting card. I find coating such parts with runny superglue makes them as hard as plastic.
