Following many requests from full size railways and model engineering societies, we have created an educational banner poster.
Using some of the technical pages from the books, the poster shows the basic principles behind the boiler and pistons/cylinders and can be used to explain how a steam locomotive works.
Size is 252 cm wide by 33 cm high (about 8 feet wide).
Printed on self adhesive vinyl, it can be used inside or outside.
You will need a suitable wall to stick it to, or you can make a backing board.
