One major project is a partnership between the U.S. Department of Transportation (DOT), the state of Illinois, the city of Chicago, Metra (Chicago’s regional commuter rail line), Amtrak and numerous private freight railroads. Known as CREATE (Chicago Region Environmental and Transportation Efficiency), billions of dollars are being invested in rail and road infrastructure improvements in and around Chicago aimed at opening up what railroaders and transportation officials alike regard as the country’s worst rail bottleneck.
