The Dan Patch Corridor is a proposed commuter rail line that would serve a region which runs from Minneapolis to Northfield, Minnesota. The corridor consists of the tracks on the former Minneapolis St. Paul Rochester and Dubuque Electric Traction Company lines, which came to be known as the Dan Patch lines. It was proposed as a passenger rail line in 2000 after being identified as a "Tier One" corridor in the Minnesota Department of Transportation's 2000 Commuter Rail System Plan before being given a study ban during the 2002 Minnesota legislative session. It sat in relative silence until 2008, when bills were introduced in the Minnesota State Legislature to potentially revive discussion.
