to answer part of my own question, Canadian National Railway (CN) bought Great Lakes Fleet, which operates most of the Taconite dry bulk ships out of Duluth. It used to belong to US Steel. I know that the Lake fleet can run straight out the St. Lawrence Seaway, and over to Europe. I found out that demand from China pushed the cost for taconite up high enough that it is now realistic to ship taconite from Duluth to China. My question has to do with how it travels. And do ocean going dry bulkers like NM or NMM have a role in that, via transshipment?
