Very nice models. So are you into HO models. They were popular up here in the city. This whole neighbourhood was built by the railroads, so there's generations of folks with collections and set ups. One of the sheets of plywood I'm using under the car was a 3D mountain scene layout of the trains running through the hills on the southwest side of the Province. The second hand shops always have old railcars and track accessories for cheap up here.
I had a big collection when I was young.... but some of the boxes were accidentally thrown out What is left is in poor condition and many pieces are probably missing/broken.
