What makes Chicago a travel hub?

Chicago's role as a transportation hub will be the topic during a Sept. 1 presentation in Glen Ellyn by the director of DePaul University's Chaddick Institute for Metropolitan Development.

Joseph Schwieterman, who wrote the book "Terminal Town," will speak at 7 p.m. at the Glen Ellyn History Center, 800 N. Main St.

Schwieterman will talk about great icons of transportation, including Chicago's Union Station, Dearborn Station, and Midway and O'Hare airports. He also will discuss lesser-known and long-gone terminals throughout the metropolitan region.

Admission is $5. For details, visit www.glenellynhistory.org or call (630) 469-1867.
