Try doing it without ever looking at the F5 HUD. There's a big lump of coal to the left. If you can almost see the bottom of it, you've got the ideal level. I find the best water level is when the red ball floating in the water tube is between the top two bars of the sight gauge holder.
i was going to make the test valves operational too, with water spraying out or not depending on the level, but I ran out of room for control variables in the engine blueprint (if i try to add one more to it, the blueprint won't open next time I try to open it),

I did notice something that struck me as odd, given the level of detail in teh whole project. At about the 3:30 mark, cylinder cocks are opened (beautiful effect by the way) and the loco moves off, but the one thing that struck me was a pale brown underside of the tender, visible from the low viewing angle. I am not sure it is a early build or it is supposed to be like that. Just thought I would mention it. Sorry if a bit obvious...
