HO 4-Car Ore Car Sets And Mini-Quad Ore Car Sets Just Announced

November 18, 2015 - M.T.H. Electric Trains has just announced new HO Scale 4-Car Ore Car Sets and 4-Car Mini-Quad Sets in Duluth, Missabee & Iron Range livery. Slated for production and delivery in the fourth quarter of 2015, the new 70-Ton Center Discharge Ore Car Sets will be produced in two different configurations; individual cars packed in a 4-car set and 4-Car Mini-Quad Sets. Roadnames for the standard 4-car sets include Canadian National and Duluth, Missabe and Iron Range. The mini-quad sets will only be available in DMIR livery. All cars feature separate, prototypical car numbers.

The mini-quad sets are offered in three numbering configurations; U29, U30 and U31. Each is offered in two sets of car numbers. All cars are indvidually numbered. The outside cars feature Kadee® couplers while the inside cars are connected by a drawbar - just like the prototype!

Historical Background

Why are ore cars so short? Because the iron ore they carry is considerably heavier than typical hopper loads like coal, so a short car of ore fills the load capacity of its trucks. Ore cars, also called “jennies,” were and still are a common sight in the Iron Range region of Minnesota and nearby states, where they shuttle between mines and Great Lakes ports. On the receiving end, jennies travel between ore docks and steel mills in a number of states. While they’re commonly associated with upper Midwestern ore-hauling roads, ore cars have in fact been rostered by nearly 50 North American railroads, and at least a dozen have owned significant numbers of jennies.

Unlike conventional coal hoppers, the prototypes of our ore car, originally built in the 1940s and ‘50s, used a construction technique that would later revolutionize grain hoppers: eliminating the center sill that normally formed the basis of a freight car underframe, in favor of heavier side sills that supported the weight of the car. This made room for “center discharge” hopper doors positioned lengthwise under the car, to dump the load neatly between the rails at ore docks.

Until World War II, ore cars generally carried “direct shipping” ore: ore that was rich enough in iron (60% or more) that it could be shipped direct to steel mills as a raw material. By the end of the war, however, the richer ore deposits began to play out. Lower-grade taconite, once considered a waste product of mining, became the raw material of choice, and by the mid-1960s accounted for the majority of ore shipments. Rather than being shipped as raw ore, taconite is refined and rolled into small pellets containing about 65% iron. Because taconite pellets are lighter than direct shipping ore, many railroads have increased the interior volume of their jennies by adding short extensions to the tops of the cars.

M.T.H. Electric Trains' HO premium rolling stock like 70-ton center discharge ore car are true 1/87 scale models of North American freight cars. Abundantly detailed with separate grab irons, steps and brake wheels ensure that these models will hold up to even the most discrminating eye. Outfitted with smooth rolling trucks and Kadee couplers make them a favorite of operators who enjoy long consists of colorful liveries, each available in multiple car numbers.

Each of these cars can be ordered from your local M.T.H. Authorized Retailer.
