Yes, that's exactly it, Mike. What a beaut of a photo.
I'd seen some Kerry Parker pics on Flickr - and established there's a potential scenic break with the line coming from the south to the east at the higher level. I was trying to work out where the next scenic break was / would be - your pic above clearly shows it would be the viaduct line from west to east.
With the release of the Bachmann 40, I'd been looking at a small (4' - 5') board with holding sidings and not the usual TMD. My layout aspirations are getting smaller and smaller! Alas, a much truncated effort would be my only option with this location.
Cheers.
