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,
