I think in terms of the loco. you're recreating it artistically, which probably (I'm assuming) gets you off the hook. Plus if it's a historical train, you probably are okay there too.

What I would like to see is one of them large WWII German type trains.. those with the extra armor on the sides. Those were always impressive to see in the old Black-n-White films. I've always been a fan of Roco Mini-Tank models... I think they are an Austrian company or so. Anyway, some years ago I discovered they have a web site where they have a whole line of European trains. Excellent and interesting stuff there.
