A coalition of interests led by Amtrak has submitted applications for nearly a billion dollars of federal funding to transform Chicago’s aging Union Station. The plan would revamp the busy station into a modern connection line between Chicago and Detroit.

Gov. JB Pritzker, along with Sens. Dick Durbin and Tammy Duckworth, Congressman Mike Quigley, Mayor Brandon Johnson, and other state and city leaders are proposing the $1.1 billion infrastructure plan, called the Chicago Hub Improvement Project (CHIP), to the U.S. Department of Transportation.

The City of Chicago and Amtrak hope to be awarded $872 million by the U.S. Federal Railroad Administration. The neoclassic Union Station would remain intact but with modern additions, including a new glass-and-steel skyscraper across the street. The upgrades would also allow the station to add more trains and potentially add a high-speed rail service to O’Hare, connecting dozens of cities with Amtrak service. The proposed projects would also include improvements for passengers traveling throughout the Midwest.
