A Full-Size "Model Railroad." How many of us had a 4 x 8 HO train layout in the basement when we were younger? Mine looked a lot like this - a mix of old and new railroad equipment (with a little narrow gauge thrown in), a depot, and a roundhouse and turntable. CRRM has been working on their "layout" since 1959. From up here it certainly looks like they went down to the hobby shop and picked up one of everything. Look carefully and you'll see nine steam locomotives, nine diesels, three "Galloping Goose" motor cars, over a dozen passenger cars, seven cabooses, three cog locomotives, and even a rotary snow plow.
