InterMountain - 65308-17 - Covered Hopper, 3-Bay, Thrall 4750 - Rock Island - 132687

Model Information: Rib-side, 3-bay covered hoppers. 4750 cubic foot capacity. Features etched metal roofwalks, sharp painting and lettering, multiple road numbers per paint scheme, and metal wheels (at least for the 2017 release - earlier releases likely have plastic wheelsets).

InterMountain does not refer to a specific prototype on their website for this model, but I have seen it referred to as both a PS (Pullman-Standard) as well as a Thrall. Perhaps the model has elements of both prototypes baked into the molding? Would love to hear from a prototype expert on this one...

Prototype History: Starting around 1970 or so, every major railcar manufacturer produced a 4750 cubic foot covered hopper. Thrall was no exception. To be honest, these hoppers all look pretty similar. To make matters worse, these cars were modified as improvements were made to the design. In the case of the Thrall model, at least two major revisions were made to this car during the period in which it was produced. The cars were built starting in the late 1970s, this 263,000 lbs GRL (Gross Rail Loading) car is used primarily for grain transport. The thrall models feature 3 bays and rib sides. The roof is flat. These cars were used by the Burlington Northern in large numbers as well as by many other railroads.

Road Name History: The Chicago, Rock Island and Pacific Railroad (CRI&P RR) (reporting marks RI, ROCK) was a Class I railroad in the United States. It was better known as the Rock Island Line, or, in its final years, The Rock. At the end of 1970 it operated 7183 miles of road on 10669 miles of track; that year it reported 20557 million ton-miles of revenue freight and 118 million passenger-miles. (Those totals may or may not include the former Burlington-Rock Island Railroad.)

Its predecessor, the Rock Island and La Salle Railroad Company, was incorporated in Illinois on February 27, 1847, and an amended charter was approved on February 7, 1851, as the Chicago and Rock Island Railroad. Construction began October 1, 1851, in Chicago, and the first train was operated on October 10, 1852, between Chicago and Joliet. Construction continued on through La Salle, and Rock Island was reached on February 22, 1854, becoming the first railroad to connect Chicago with the Mississippi River.

In 1980 Rock Island was liquidated. The railroad's locomotives, rail cars, equipment, tracks, and real estate were sold to other railroads or to scrappers. William Gibbons (the trustee) was able to raise more than $500 million in the liquidation, paying off all the railroad's creditors, bondholders and all other debts in full at face value with interest. Henry Crown was ultimately proven correct, as both he and other bondholders who had purchased Rock Island debt for cents on the dollar during the low ebb in prices did especially well.

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.
