Scale Rail Don,
Thank you so much for posting the photos of Jim Madden's layout. I figured it would have been dismantled and only exist in memories. I remember Jim at the Montera Middle School Monthly TCA meets with His Trademark Train Signal Sweater.
Here's two pics I found (dated 1977) of a TTOS event hosted by my Dad.
From left to right: Fred Hines (I think?), Jim Locke Brown (spelling?), George DeLucas, Dennis Mutulo.
