Hmmm, a raven that stands shin level. Seems to be a fairly normal person to me. If anything on the shorter side. Not seeing what you're getting at there.
Probably referring to the width between tracks, trains are generally pretty wide and their tracks are about as wide as a Western car. So either this train was very slim or old, or Eastern trains might have a design that allows thinner tracks, but I doubt either of these things. It's a nice convincing composition regardless of the accuracy.
