MONTREAL — Canadian National is acquiring 600 new iron ore jennies for its former Duluth, Missabe & Iron Range Railway operation in Minnesota.

Freight Car America is building the cars in Mexico using materials from U.S. Steel, the onetime owner of DM&IR. CN transports iron ore pellets mined by U. S. Steel to the company’s mills through a network that includes the railway, docks, and Great Lakes vessels.

“By transporting iron ore pellets mined by U. S. Steel through our extensive rail network, docks, and vessels to U. S. Steel mills, we facilitate the safe movement of raw materials. These, in turn, can be utilized in the production of many things the economy needs, including our iron ore jennies. This integration exemplifies our commitment to powering the economy,” Helen Quirke, CN’s vice president of supply chain and business development, said in a statement.

“The next generation of ore jennies has arrived, and we are pleased that not only were U.S. Steel materials used in making them, but we are implementing them at our Minnesota Ore Operations facilities,” James Jarvi, U.S. Steel’s director of logistics, pellet movement, technology and sustainability, said in a statement. “Steel that’s mined, melted, and made in America starts with iron ore, and the ability to move it from the mine to the mill quickly and efficiently. This partnership will help U.S. Steel make that possible.”
