The Chicago, St. Paul, Minneapolis and Omaha Railway or Omaha Road (reporting mark CMO) was a railroad in the U.S. states of Nebraska, Iowa, Minnesota, Wisconsin and South Dakota. It was incorporated in 1880 as a consolidation of the Chicago, St. Paul and Minneapolis Railway and the North Wisconsin Railway.[1] The Chicago and North Western Railway (C&NW) gained control in 1882.[2] The C&NW leased the Omaha Road in 1957 and merged the company into itself in 1972.[3] Portions of the C. St. P. M. and O. are part of the Union Pacific Railroad network. This includes main lines from Wyeville, Wisconsin, to St. Paul, Minnesota, and St. Paul to Sioux City, Iowa.
