.....re trains, here's a (although modern) reference tube for military steam, it gives a little bit of an idea of what WWII transport must have been like.
Again I think the rail upgrades are great, many thumbs up, yet and I think maybe it's been mentioned here before that it's a pity the smoke can't be a lighter grey or even white, additionally extra steam coming out of the valves onto the track bed would complete the package, maybe one day.
