The book Forgotten Chicago includes the claim that at Chicago’s railroad peak, 1,000 trains daily moved in or out of the city. One chapter of the book details the numerous train stations that are no longer standing that serviced these trains.

Chicago continues to be a railroad center in the United States even if the volume of trains is not close to the peak numbers.

And as train travel declined, the Chicago region became home to other transportation options. Two of these are worth considering after the golden age of railroads passed (and Chicago’s port activity also declined). As people used trains less to travel between cities and used trains less within the region as commuting between suburbs picked up,

First, O’Hare Airport is one of the world’s busiest. Today it has over 900 daily flights (mostly domestic, some international). By number of passengers, it is in the top ten among global airports. I do not know how many people moved through Chicago via train at the peak but the flight numbers are large.

Second, many people travel throughout the region and to other regions via highways. For example, one interchange of two interstates roughly 20 miles west of the city has about 300,000 vehicles daily. Numerous highways throughout the metropolitan area have daily traffic counts of over 100,000 vehicles. That is a lot of cars and trucks moving people and goods around.
