On the early plat maps of Morrison County, Minnesota, among out ancestors' 160s and 280s, there was a LOT of land owned by "C, ST P, M & O Ry". Sure, I knew it was a railroad, and that they were granted land in case they decided to build the actual track here...or here....or here? And what they didn't use for a track, they could sell off.
Still, I'm used to BN or GN or Soo line, so tonight, I finally looked it up:
The Chicago, St Paul, Minneapolis and Omaha Ry.
