CHICAGO (AP) — Amtrak is offering discounted tickets for passengers traveling to southern Illinois to view the upcoming total solar eclipse. A coast-to-coast total solar eclipse — where day briefly becomes night — will occur in the U.S. on Aug. 21 for the first time in 99 years. It’ll last the longest near Carbondale, Illinois. That’s where thousands of people are expected to gather to experience less than three minutes of darkness. Passengers traveling to the area between Aug. 16 and 22 may save 30 percent.
