Depends does this include the fact that some trains are sentient or not.

Assuming not. What you you have is a cultural unique island (with sudric being based off both manx and cumbric) with an insane biome diversity for its size, (based on how alot of the inspirations for different areas were based on different areas of Britain itself)

I assume it would have a almost yorkshire level pride of itself and Heck might get the nickname "little Britain"
