Looks like a very believable train. Am I right? I like everything I see, really a pleasure for eyes.
Only 2 tiny complaints... or maybe it's better to call them just advices.
The carpet pattern is a little bit out of place, it should be something a lot more simpler, something plain like that for example

And another thing is wood texture of the chairs. It looks a bit... hard to say... it looks a bit too rough, I do not know how else to explain. The wagon itself looks like a class A so the wood should be ia shiny lacquered wood like that for example
