The Canada Energy Regulator says rail shipments of oil in September amounted to 94,440 barrels per day, nearly double the 51,000 bpd shipped in August. Only 39,000 bpd was shipped in July. That's less than a tenth of the record 412,000 bpd moved by rail in February.
Rail transportation of crude oil is considered to be more expensive than shipping by pipeline so shippers tend to use it only when pipelines are full or if the destination market offers much higher prices than can be achieved in Canada.
We are still mired in the economic abyss created by the inappropriate economic crushing reaction by governments. And yet, rail shipments of oil in September were up 150% from the July shipments. Just another reason to own ENB shares
