This happened the other day around here. A lowboy became stuck on a crossing with a new cat 320DL excavator. Soon later a Amtrak train came and smashed into the truck totaling the excavator, lowboy ,and the train engine. No one was seriously hurt. very good video of the accident http://www.youtube.com/watch?v=bS4gUQRiL78 Then a tractor trailer crashed into the back of another stalled truck going 70 mph. This shut down the hwy for almost 8 hours.
