So flooding risk has become high as the snow melts in Iowa. My parents in 2 weeks are taking the CZ from OMA-CHI on coach. What is the risk for the CZ? Will they detour onto the UP line through northern Iowa (actually that might be cool)? Will they get bustituted or will the train get canceled? I know this was a problem last year and forgot what Amtrak did. Any reassurances or answers would be nice. Thanks, I really want my parents to have a great Amtrak experience!
