Normally, car carriers are meant to protect cars from the dangers of the road during transport. However, if the guy driving the truck is one of the unlucky few who gets his trailer nailed by a train, well, I don't have to tell you how much protection that offers.
Unfortunately, a truck carrying this antique Rolls Royce limo zigged when it should have zagged, and got nailed by a passing train while the truck's trailer was high-centered over a track crossing. The truck's driver called 911, but authorities weren't able to get in touch with the train's engineer in time to stop the train. And because it can take a while to slow down a freight train, what's done was done.
