While we're on the Terraserver kick, here's the place that started it for me. Rock Island roundhouse at Goodland, Kansas, 24 stalls,later reduced to 14, razed 1956, along with backshop. Turntable (100') installed 1943, still functioned last I knew, used to turn the occasional snowplow. One stall pre-fab metal enginehouse that replaced roundhouse was abandoned at my last visit, would be good building for restoration work.
