. Each coal car is turned completely upside down to empty the contents into a hopper which in turn loads it onto a conveyor belt to the stockpile.
This is done on a continuing basis; As soon as one train is emptied, another train is standing by ready to take its place so yes, it can be a pretty dusty environment
. And even though this coal dock
is in Canada
, the product comes from the good ole USA because, they don't want this type of dirty export operation in that grand ole country. I think it might be one of those NIMBY situations, so let's ship it through Canada
Although the operation is mostly automated, I guess we should be thankful it provides a few jobs.
Strange though it might seem, Uncle Sam does not want our dirty oil
from the Alberta Tar Sands run through a pipeline to the G.o.M. ... Pres. Obama squashed that for us so one can hardly call it tit for tat.
