   Also in this case the SUV's fuel tank burst into flames and somehow the rails   
   got ripped up and pierced the rail car.  This probably speaks more to the   
   structural design issues of the *SUV* on the one hand and I am not sure what   
   it says about the roadbed construction (eg how well secured the rails   
   were/weren't).
