WINONA Minn. – The Chicago & Northwestern beefed up its Winona service in 1950 with a new train called the Dakota 400. The yellow streamliner carried a hospital car with an extra wide door to accommodate stretchers for Mayo Clinic patents. The new service replaced the former Minnesota 400, which ran 460 miles from a Chicago-St. Paul mainline connection in Wyeville, Wisconsin, to Huron, South Dakota. The new Dakota 400 in 1950 originated in Chicago for a 690-mile run that avoided transfers in Wyeville. The hospital car went as far as Mankato, where it was unhooked and then picked up on the return trip to Chicago.

The Elroy stop. The Dakota 400 on the Sparta-Elroy cut-off before the steep 3% grade and its three storied tunnels were abandoned. At one point the C&NW ran 50 freights and six passenger trains a day through Elroy. Points west were Sparta, LaCrosse, Winona and the even steeper 4% Lewiston grade to Rochester, The turnaround point was Huron South Dakota.
