Specific Item Information: Milk Tank Car

Prototype History: A refrigerator car (or “reefer”) is a refrigerated boxcar (US) or van (UIC), a piece of railroad rolling stock designed to carry perishable freight at specific temperatures. Refrigerator cars differ from simple insulated boxcars and ventilated boxcars (commonly used for transporting fruit), neither of which are fitted with cooling apparatus. Reefers can be ice-cooled, come equipped with any one of a variety of mechanical refrigeration systems, or utilize carbon dioxide (either as dry ice, or in liquid form) as a cooling agent. Milk cars (and other types of “express” reefers) may or may not include a cooling system, but are equipped with high-speed trucks and other modifications that allow them to travel with passenger trains.

By the 1940's, new reefers were being built entirely of steel. Insulating techniques improved to the point where economical refrigeration could be accomplished using steel side plates in place of wood sheathing. Cars with steel roofs and sides were more durable and required fewer repairs.

The General American Transportation Corporation built several 40' steel reefer for the Union Refrigerator Transit Line (URTX) from the late 1940's into the 1950's.
This reefer was 40' long & weighted 61,500 lbs. The car is a steel bodied reefer with iced bunkers at each end. These ice bunkers hold 10,400 lbs. of chunk ice or 11,500 lbs. of crushed ice. Ice stations were located every 100-150 miles along the railroads main line to replace the melted ice. In the winter, charcoal heaters could be placed in the bunkers to keep the cargo from freezing. Fans are located in the floor at each end to circulate air and keep an even temperature throughout the car. Typical cargo would be fresh fruit, vegetables or eggs.

American Car & Foundry (ACF Industries) also built 40' reefer for several companies.

Road Name History: The Sheffield Farms–Slawson–Decker Company, known as Sheffield Farms,  was a dairy that pasteurized, bottled, and delivered milk in New York City in the first half of the 20th century. It became one of the largest dairy companies in the world, selling 20% of the city's milk.
The company was sold to the National Dairy Products Corporation, that was formed in 1923 as a merger of several dairy concerns and continued to grow through acquisitions, the most important of which was the addition of Sheffield Farms. Others included Breyers Ice Cream, also purchased in 1926, and Kraft-Phenix Cheese Corporation, in 1930. All of the companies continued to operate independently, marketing products under their recognized brand names. In 1969, National Dairy Products became Kraftco and then Kraft in 1976.

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.
