I had a look at your train. Indeed it looks very good. There is however a problem with the piston-rods and connecting rods (between the wheels). If I see it correct, the train will never be able to run as the connecting rods will prevent the wheels from turning! Or do I misunderstand the mechanism?

Yours sincerely,

hi raymond its just a eirst attempt at drawing actually the connectors go on the opposite sde and the slide valves are bigger and also 2 on each side also the steam chests are a lot bigger but thats nice observation
