Nice job on the scene! It looks great, and it functions perfectly as designed.

The only issue that I have with it is the fact that the Walschaerts valve gear was used to regulate the flow of steam to the pistons in STEAM ENGINES. The type of engine you show in your scene is an internal combustion engine, which does not make sense! And there is also one important component missing from this Walschaerts valve gear, and that is the control arm which allows the train Engineer to adjust the efficiency of the valve timing, and also allows him/her to smoothly change the direction of movement of the train between forward and reverse.

Except for those details, you did an excellent job on the scene. It's awesome!

Its a nice engine, but I have to agree with what Xray said. Regardless, this is a very nice scene, Phun User! Can't wait to see what else you can make

Thanks! It does have a (sort of) reverse function. the expansion link can go backwards, but I've blocked it off due to not knowing how to control that and the timing of the engine at the same time. And on the combustion engine; I've done that for the purpose of not knowing how to make it work like a real steam engine, that was the only way I knew how to make it "work" at the moment. But thank you for your input!

Cool engine!
