For the first time in the modern era, an Amtrak test train is scheduled to run 110 miles-per-hour while carrying passengers. The burst will happen along a 15-mile section of track connecting Chicago and St. Louis.

The maximum speed will be reached between the towns of Dwight and Pontiac in Illinois, a stretch between 80 and 100 miles south of Chicago. 110 is the highest speed allowed on Amtrak trains operating west of Pennsylvania and New York.

The trains normally travel at a top speed of 79 miles-per-hour.
