Canadian National Railway in Northeast Minnesota - Iron Ore Trains

Описание: Canadian National Railway in Northeast Minnesota - Iron Ore Trains - Spring 2021

In this video we see Canadian National trains operating in Northeast Minnesota from Duluth to the Iron Range to Two Harbors with a variety of EMD and GE power including SD40's and Dash 8. We start out in the far western end of Duluth at Nopeming Junction for a couple of CN freight trains climbing and descending Steelton Hill on the CN Superior Subdivision. Then we make our way to north to the Iron Range and see a CN ballast train, empty Minorca limestone, and the Keenan Switch on the CN Missabe and Mintac Subs. As a bonus added a BNSF ore train on the BNSF Casco Sub. Later we make our way over to the CN Iron Range Sub and see a pair of Norfolk DC-to-AC test units in Mintac ore service. Initial reports say the pair are performing well. To end the video we see both a loaded and empty Mintac ore trains lead by GE dash 8's. Video was shot with an iPhone XS and GoPro 9 Black.

The Duluth, Missabe and Iron Range Railway (DM&IR) (reporting mark DMIR), informally known as the Missabe Road, was a railroad operating in northern Minnesota and Wisconsin that used to haul iron ore and later taconite to the Great Lakes ports of Duluth and Two Harbors, Minnesota. Control of the railway was acquired on May 10, 2004, by the Canadian National Railway (CN) when it purchased the assets of Great Lakes Transportation.

Taconite (IPA: ['tækənaɪt]) is a variety of iron formation, an iron-bearing (over 15% iron) sedimentary rock, in which the iron minerals are interlayered with quartz, chert, or carbonate. The name "taconyte" was coined by Horace Vaughn Winchell (1865–1923) – son of Newton Horace Winchell, the Minnesota State Geologist – during their pioneering investigations of the Precambrian Biwabik Iron Formation of northeastern Minnesota. He believed the sedimentary rock sequence hosting the iron-formation was correlative with the Taconic orogeny of New England, and referred to the unfamiliar and as-yet-unnamed iron-bearing rock as the 'taconic rock' or taconyte.[1]

Following development of high grade direct shipping iron ore deposits on the Mesabi Range, containing up to 65% iron and as little as 1.25% silica, miners termed the unaltered iron-formation wall rock taconite. The iron content of taconite is generally 30% to 35%, and the silica content generally around 45%. Iron in 'taconite' is common present as magnetite, iron silicates, and iron-bearing carbonates, and locally martite (hematite) formed by oxidation of magnetite. Horizons containing magnetite as the dominant mineral have been extensively mined since 1955 to produce iron ore pellets; the term 'taconite' has consequently been colloquially adapted to describe the magnetite iron-formation ores (taconite iron ore), the mining, milling, magnetic separation, and agglomerating process (taconite process), and the product iron ore pellets (taconite pellets).
