How soon we forget! Just 3 years ago on Feb 1-2 2011, Chicago was hit with a blizzard that dumped over 21" of snow and drifts as deep as 6 feet or more.
Lake Shore drive had over 900 abandoned cars stuck on it. All local transit was suspended.
Amtrak shut down all of its trains from Chicago for 3 days. No service anywhere. I know, as I had a friend returning from LA on #4 in a sleeper and they offloaded all passengers in ABQ where they stayed at a Hotel for 3 days until the route was reopened.
Also the airport was closed for 2 days with over 1500 flights in Chicago cancelled .
Stuff happens. Weather has always plagued all forms of transportation whether we like it or not.
