InterMountain - 65231-04 - Covered Hopper, 4-Bay, Cylindrical - Procor - 121797

Specific Item Information: BLT: COTS ABDW 11-79

Model Information: These models are available in two different configurations - "Trough" hatches or "Round" hatches. Prior to their more recent "Ready-To-Run" state, they were available in kit form. Intermountain doesn't actually specify a prototype for this model, but it appears to be based on an NSC (National Steel Car) 4750 cf hopper.

Prototype History: ACF introduced their roundish cylindrical hoppers in the early 1960s. The cars differed greatly from the ribbed sided hoppers of the era. They have been made in 3-bay and 6-bay variations. These cylindrical hoppers were superseded on ACF’s production line by the Centerflow in 1964, a revolutionary design that influenced later covered hopper types. In the late 60s or early 70s Canada came out with 4-bay covered hoppers that appear to be derived from ACF’s pre-Centerflow cylindrical hoppers. These cars were used by CN, CP and various smaller Canadian shippers. There is some question as to why the Canadian builder based their design off the older cylindrical and not ACF’s newer Centerflow. It was likely a patent issue and copying it could have triggered legal action against the Canadian builders. There are also certain structural design differences between the cylindrical and centerflow cars and perhaps the decision to copy the cylindrical was based on the greater volume capacity of the cylindrical design.

Road Name History: Procor is a Canadian company producing railway shipping cars. It is Canada's largest private rail car rental fleet, with more than 21,000 conventional and special-purpose tank and freight cars. Linked to Sparling Tank Car of Toronto, Procor was founded in 1952 as Products Tank Line Limited and became an affiliate of US-based Union Tank Car Company. Within a few years they had become a major player in Canadian tank car operations through the acquisition of the Transit Co./Imperial Oil fleet in 1955, along with a number of smaller operators such as Canadian Industries Ltd. circa late 1956. The company, which shortened its name to Procor in 1962, is headquartered in Oakville, Ontario.

Brand/Importer Information: InterMountain was founded in 1985 by Fred Brummet. They got started in the model railroad business by producing O-Scale model kits. They got started in the N Scale business almost a decade later when in 1994 they introduced the 40-23 reefer car in kit form. Later, in 1998, they started producing RTR (Ready-to-Run) models. By the early 2000s, InterMountain phased out kit production in favor of the RTR models.

The InterMountain Railway company is located at 1224 Boston Ave in Longmont, CO. They are a manufacturer of HO, N and Z scale model trains. They have produced kits as well as RTR (Ready-To-Run) models. Their N Scale products include locomotives as well as rolling stock. Their rolling stock lineup includes Boxcars, Hoppers, Tank Cars, Reefers, Gondolas, Stock Cars and Flatcars.

Their locomotive releases have primarily been diesel units, with the one major exception being their series of AC-12 Cab Forward steam locos. Their diesel lineup includes F3's, F7's, F9's, SD40's, SD45's and FT units. They are known for quality and detail. They also release their rolling stock in larger varieties of road numbers than most of the other manufacturers.
