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 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!
