I spent much of last week in Sioux Falls. I saw the four remaining depots--GN, CRIP, IC and MILW. CNW also served Sioux Falls, although passenger service was gone at some point before 1955. Does anyone know if CNW had its own station in Sioux Falls and, if so, where it was located and when it was torn down?
I have no idea.
But if C&NW shared a depot, I'd guess it shared with the Great Northern. First off, is it really a good idea for each railroad to have its own station in such a small city? There's already three others. Someone must have got wise, and shared with a railroad with a different geographical base. Second, both C&NW and Great Northern shared the same general route into the city from the east.
