Trains crash, Mr. Pitt, all the time. Usually on bridges over waterways, or in towns. One tanker train wreck does more damage than all the pipeline leaks from our whole two million miles of pipe, and has a pretty good chance of killing more people than all those pipeline accidents put together as well.
Yet, you don't seem to have a problem with the same oil moving on BNSF trains owned by Obama-booster Warren Buffet. Could it possibly be that your 'ethics' are merely politically convenient, and nothing more?
