SPRINGFIELD – After a test phase, Amtrak is whisking rail passengers at a new top speed of 110 mph over a short section of its route between Chicago and St. Louis in a step forward for the Midwest high-speed rail program, officials said Thursday.

Trains accelerate to the higher speed over a 15-mile segment between the central cities of Dwight and Pontiac in an upgrade that Amtrak and state officials hope will generate buzz during the busy holiday travel period. Although it is still losing money, Amtrak is experiencing record ridership numbers on many routes around the country.

"This next-generation rail system gives passengers a safer, more reliable way to travel across Illinois and connect with family this holiday season," Gov. Pat Quinn said in a statement announcing the achievement.
