Normally I am not a fan of ovals. However, the compact Canyon City RR track plan by the late George Bastert caught my attention, because offers many features of general interest (at least for me). In my C track translation it measures 110 x 190 cm.

The single level construction is rather simple. Having all turnouts accessible from the front, the layout can be "surrounded" by three walls. Train meets are possible, the highway overpass allows to hide an entire train, thus making a train run seem to be long(er). There are both siding capacity and switching potential. Stub tracks disappearing "in the distance" under the overpass plus the placement of mirrors add scenic depth and simulate a connection to a greater world.
