Nice layout for a 4x8. I like your turnout / spurs, and the neck-down inner loop.
Is that a Lionel Jr. whistle station or transformer station in the left foreground? I recently fixed up a station shell, but I have no guts for it yet. Some station end-panels have a vertial slot, and some have a curved/arched slot, and I'm not sure which is for which ??? Or for different types of transformer control arms ??? Any clues?
