Which is the best delivery system for fossil fuels?.....  Pipelines or Railways? Well that is a lot like asking..... which is a better delivery system for drugs? Snorting, smoking, ingesting, suppositories, or mainlining? This question is a smokescreen to prevent us from looking at the overall major devastations caused by fossil fuels. 
Trudeau,Notley,Clark and ilk are all trying to brand pipelines as more green than railways. This is a desperate attempt to hoodwink British Columbians and other Canadians to accept the Trans Mountain Pipeline. Be aware!
