I have to take issue with the conclusion that Sodor is a communist state.
It’s The Other Railway that is the socialist nationalised British Railways. Also, I remember there being fear and anger at the possibility that the engines would be replaced by diesel or electric engines who would pull their carriages (who were all female back when I read the books last). The few diesel and electric engines that are on Sodor are treated as a lower class than the steam engines.
So, we have an island where there is propaganda causing a strong hatred of socialism, and a belief that immigrants will come to take their jobs and women. Sodor is clearly a fascist regime, not a communist one.
Sorry, Thomas and Friends are all Nazis.
I’ll be back later to destroy another treasured childhood memory.
