Thanks for all this info. My project began some years back and has slowly been mutating. I bought a fair amount of stuff when I was working (and had money but no time). Now I'm retired I'm gradually refining my ideas. I just sold a couple of musical instruments which has led to some railway purchases. Abandoned have now my original fictional beltline/interchange concept, sticking with actual lines, but in a fictional way. The fictional belt/interchange company has been replaced by the EJ&E, and the date range has expanded from 1937 to up to 1940, so still (for the US) pre-war, but with an increased admixture of diesels amongst the steam.
