The Canadian Pacific Kansas City's Merriam Park Subdivision or Merriam Park Sub, also known as the Short Line, is a railway line in Saint Paul, Minnesota. It is run by the Soo Line Railroad, a U.S. in-name-only division of CPKC. It runs from the Saint Paul Yard, also known as the Pigs Eye Yard, westward to the Short Line Bridge over the Mississippi River, where rails continue as part of the Minnesota Commercial Railway. It was named for John L. Merriam, a Minnesota banker and politician. Completed by the Chicago, Milwaukee and St. Paul Railroad in 1880, it shortened the route Milwaukee Road trains took between downtown Saint Paul and downtown Minneapolis. Previous trains would exit Saint Paul and follow the Mississippi River southwest until crossing at Fort Snelling, where they would follow the path of today's Hiawatha Avenue (Minnesota State Highway 55) and the Metro Blue Line toward the Milwaukee Road Depot. Originally built as an interurban route, it was eventually converted for heavy rail traffic because the Twin City Rapid Transit streetcar system had taken over the local transit market.
