Zip Rail is a proposed intrastate passenger train that would link the Minneapolis–Saint Paul metropolitan area with the city of Rochester. There has not been a rail line linking these cities since the 1960s. If Zip rail goes forward a new rail line will have to be built. The project was previously branded as Rochester Rail Link.
North American High Speed Rail Group (NAHSR) has proposed building a HSR line on the same route. This is a separate proposal not connected with Zip Rail.

Past studies
Previous to Zip Rail, supporters had pushed for a Chicago - Minneapolis High Speed Rail ( HSR ) routing through the city of Rochester. This routing was not chosen, largely due to the added costs to routing to Rochester versus the Mississippi River corridor.
Tri-State Study
The Tri-State Rail Study[1] was commissioned by the Illinois, Wisconsin, and Minnesota Departments of Transportation (hence the "Tri-State" name) and was completed in 1991. It examined the feasibility of train services on several routes, narrowed to two by 1990.[2] The current route of Amtrak's Empire Builder was among those discarded and not studied in detail, but it was listed as a simple route comparison.
- Route No. 1, Amtrak's current route: Chicago to Milwaukee, then northwest to Portage and Tomah, then west to La Crosse before crossing the Mississippi and mostly running on the west side of the river to the Twin Cities. The "Amtrak upgrade" option for the southern corridor would make use of some of this right-of-way.
- Route No. 4, southern corridor: Chicago to Milwaukee, then straight west to Wisconsin's capital city of Madison, then up to Portage, west to La Crosse and on to Rochester, then turning north to the Twin Cities. This route was studied at 125 mph (201 km/h) (a so-called "Amtrak upgrade"), 185 mph (298 km/h) (TGV/Inter-City Express-class service), and 300 mph (480 km/h) (maglev).
- Route No. 7, northern corridor: Chicago to Milwaukee, then continuing north to the Green Bay/Fox Cities region, and westward through Spencer and Eau Claire before reaching Minneapolis–Saint Paul. As no passenger rail exists on this route beyond Milwaukee, it was only studied at 185 (TGV/ICE) and 300 mph (maglev).
The study concluded that the "Amtrak upgrade" 125 mph option on the southern corridor through Rochester had the best direct return on investment, and was the best option for a capital-constrained public endeavor. If money were more readily available, the study recommended 185 mph operation since this created the greatest net consumer surplus NPV. A privately funded endeavor would have the best luck at attempting a 300-mph maglev train, because it provided the greatest gross consumer surplus present value. In all cases, the southern corridor outperformed the northern corridor in the long term. The study made mention of "newly introduced Swedish Railroad 'tilt' technology", but it was not studied.

Tri-State II Study
The Tri-State II High Speed Rail Feasibility Study[3] was commissioned by the Minnesota and Wisconsin Departments of Transportation and built upon the previous Tri-State study, plans from the Midwest Regional Rail Initiative (MWRRI), and a 1997 study looking at the Chicago–Milwaukee corridor. Since the MWRRI plans advocate 110 mph diesel or diesel multiple unit (DMU) technology (described as "incremental" by the study authors), this was used as the base case for the study.
This study also included gas turbine-powered trains, in comparison to diesels and electrics. It concluded that gas turbines operating at 150 mph were the best option. Development could begin at 110 mph, but the study authors stated the corridor should be developed to 150 mph standards to allow faster trains later.

Rochester Rail Link Study
In contrast to the previous two studies, the 2003 Rochester Rail Link Feasibility Study[4] focused on a spur link to Rochester from the Twin Cities, but avoided discussing the merits of the city's presence on a line to Chicago in significant depth. The routes recommended in that study had one terminus at the Rochester International Airport (RST) at the southern end, and closely examined linking to downtown Minneapolis and to Minneapolis-St. Paul International Airport (MSP).
The study examined three motive-power options and recommended a TGV-like service linking the Twin Cities and Rochester using electrified trains operating at speeds up to 185 mph (298 km/h). In this study, the trains would carry a mixture of passengers and cargo, allowing the Rochester airport to take over some of the air freight capacity of MSP. In the leading example, a rate of 20 passenger trains per day was proposed, plus 4 freight trains in the overnight hours. The passenger estimates were made not based on projected market demand and supply but on a simplified model that if X number of seats were available, Y percentage of those seats would be filled at a Z price. The cost estimate for building the electrified line was $869 to $933 million (2002 dollars), largely depending on whether an entirely new route was used or if the line would closely follow Highway 52. The analysis indicated that the line would eventually pay for itself with passenger and cargo revenues more than covering the capital and operational costs over a 30-year period.

Tri-State III Study
The Tri-State III High-Speed Rail Study[5] of 2009 was commissioned by the Southeastern Minnesota Rail Alliance, a rail advocacy group based in Rochester. This study is partly a rehashing of the Tri-State II study, but with greater detail in examining the speeds possible along the current Amtrak route along the Mississippi River versus what would be possible by going through Rochester. There are many segments along the river that can only support 90 mph top speeds or lower due to relatively sharp turns.
The study concluded that 220 mph service via Rochester, which is a higher speed than what has been recommended in other studies for a publicly funded system, would be the best option and would be the most profitable. The study authors noted that the amount of funding available for the project in Minnesota is constrained. Because of this they suggested going utilizing diesel-electric powered 110 mph service via Rochester. They claimed this would be profitable. They called for the route to allow for future upgrades and improvements that could be done over time.
