Perhaps a better O54 yard:
If you look closely, you will see the yard has two O54 'S' curves - but probably OK as they are O54. There are two O54 cross-overs with 'S' curves as well.
Two of the yard spurs are 50+", and the other three are 40" long. Twenty-two 10" freight cars.
The five industry spurs are only accessible from the O45 section, so a smaller loco can handle those.
