The Trains | Metra City | Metra Suburban | Airport Express | Amtrak and High Speed Rail | Feeder Buses

The KTX system in Korea offers an excellent model for high-speed rail development in the Midwest.

Most high-speed train systems across the world feature trains travelling at speeds up to 220 mph on dedicated tracks in the countryside, and at reduced speeds on conventional tracks in the cities. CrossRail Chicago will serve as the access point for high-speed trains. It would be similar Seoul's KTX high-speed trains which share tracks with local trains and AREX airport express trains between downtown and Incheon International Airport.
