states. The Chicago-based routes receiving funding were: $1.131 billion for Chicago–St. Louis–Kansas City ($1.1 billion for Chicago–St. Louis, $31 million for St. Louis–Kansas City) $823 million for Chicago–Milwaukee–Madison–Minneapolis/St. Paul ($810 million for Milwaukee–Madison, $12 million for Chicago–Milwaukee, remaining $600,000 to study possible alignments to the Twin Cities.) $244 million for Chicago–Pontiac–Detroit An additional $400 million was released for the 3C corridor in Ohio connecting Cleveland, Columbus, Dayton, and Cincinnati, and $17 million was allocated to Iowa. Many of the corridors receiving funding at this time were originally designated as high-speed rail corridors following the 1991 ISTEA legislation. 2010 In October 2010, the Chicago Hub received more money from the FY 2010 High Speed Rail Allocation. The major grants were: $230 million for Chicago–Quad Cities–Iowa City $161 million for Chicago–Detroit Following the 2010 gubernatorial elections in Wisconsin and Ohio, both newly elected governors repeated their intentions of shutting down the projects in these two states and returning the money to the federal government. Following the return of funds, the federal government redirected the $145 million intended for Wisconsin and Ohio to the State of Washington's high-speed rail corridor, and to Connecticut to modernize the New Haven-Springfield Line. Chicago-St. Louis rail line upgrades Before the upgrades, Amtrak passenger trains had a top speed of 79 MPH on the line between Chicago and St. Louis, and freight trains had a top speed of 60 MPH. In the fall of 2012, the section of the Chicago-St. Louis line between Pontiac, Illinois, and Dwight, Illinois, began Amtrak service at 110 MPH, as a demonstration section. In 2014 construction began to upgrade the entire rail line between Carlinville, Illinois, and Joliet, Illinois, so that Amtrak could run its passenger trains at 110 MPH. In addition, freight trains will be able to operate at 70 MPH. The entire cost of the high-speed rail program was estimated at $1.8 billion, with the federal government committing $1.6 billion of that, later lowered to $1.4 billion. It is estimated that $1.2 billion will be spent on the program by the end of 2016. Beginning December 20, 2021 Amtrak trains are now running up to between Chicago and St Louis. This reduced travel time by 15 minutes between the two cities. Amtrak hopes to upgrade the line to operation by June 2023 which would save an additional 45 minutes in travel time.
