Merriam Park Subdivision

The Canadian Pacific Railway Merriam Park Subdivision or Merriam Park Sub, also known as the Short Line, is a railway line in Saint Paul, Minnesota, which runs from Pig's Eye Yard and the CP River Subdivision in the east to the Short Line Bridge over the Mississippi River in the west, 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 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.

Passenger trains continued to use the Short Line into Minneapolis until 1971 when the Hiawatha stopped service with the formation of Amtrak. Amtrak's Empire Builder continues to use the eastern portion of this line as of 2016 but the train exits the subdivision to the north into Minnesota Commercial Railway trackage to reach the now unused Midway station in Saint Paul. Amtrak returned to using Saint Paul Union Depot in 2012, but continues to route trains in the same way.
