Illinois and the federal government have approved an environmental impact statement for the high-speed rail line under construction between Chicago and St. Louis.
The review is an important step because it identifies a route through Springfield that would end a dispute that had threatened to hold up the project.
It also recommends a route around some of the congested tangle of rail lines between Chicago and suburban Joliet. Upgrades to that suggested corridor would be $500 million cheaper than the existing route because fewer overpasses would be needed.
Illinois Governor Pat Quinn was on board Friday when an Amtrak train reached speeds of 111 mph for the first time along a Chicago to St. Louis route. The train hit the mark on a stretch between Dwight and Pontiac before braking back to normal speeds of 79 mph. By the end of November, paying passengers will get to experience the higher speeds on that initial section between Dwight and Pontiac.
