One railroad train hauls at least 80 cars and many of those cars haul chemicals most of which are toxic. While accidents are rare they do happen and when they do, there are the enevidable spills not only of toxic chemicals, but also the fuel to power the train. The amount of chemicals in each car is huge, and while I can't say with any certenty the number of these chemical cars make up the typical train, I'm sure that there are those in this forum who can, so I'll not even try.
My question to you though is this ... would you bar railroads from hauling toxic chemicals on the assumption that there could be an accident?
I believe in tighter regulations....and so do others......
