On January 7, 2008, a fierce tornado producing up to 160 mile-per-hour winds blew across two northern Illinois counties. The twister was unusual for two reasons: First, the temperature and weather conditions were more typical of a midwestern spring than mid-winter. And second, the storm blew 12 railroad cars off the tracks.
The truely scary part of this video is when you realize that the big thing sliding along the tracks toward the train engine, past the blown off cars, is a huge tank car that is throwing up a shower of sparks! What’s in the tank? Hopefully not gasoline!
