Hi Chris.
A few comments. The CN stations dominated one whole section of the NMRA contest table, but I don't know what prizes he got. Most of them had merit awards with over 100 points.
The first little layout you showed is Underneath the Arches and has 3 or 4 gauges on it - from O standard on down through OnHO to OnN. The builder's forte is figure painting.
I remember seeing that car barn on the Grand River Rly in Preston when it was still electric (no passenger service). There were no frogs in the overhead -- each siding wire came back and ran parallel to the main line wire for a distance. They used poles and had to shift from wire to wire by hand. In more recent years, my wife and I have picniced in park next to it. The barn was torn down not too many years ago.
