Very nice work so far. Looks like you're pretty well set inthe rolling stock department.

If I can make a suggestion, it looks like you've got pleny of yard space but, unless I'm not seeing it in the pictures, it's all stub end and you have no crossover or run around tracks anyhwere in either yard. That makes it really difficult if you need to pull just one car from track 3 for a train or if you need to pull multiple cars from different tracks to make up a train. You could solve this prolem partially by connecting that top yard track to the inner loop track so you'd have both a long yard lead to make up trains and two ways to get back to your main line. You may already have this issue solved and I can't see it in the picture but I'd learned from sad experience that maximizining yard space alone is not a good thing.
