Roundhouse - 8605 - Open Hopper, 3-Bay Steel - Rio Grande - 18622

Prototype History: The 1960s brought about a growth in car size (and capacity). Railroads that transported coal moved away from the older 2-bay 55-ton USRA standard to newer 90- and 100-ton three bay hoppers. These cars were effective and long-lived. Many railroads swapped out the trucks on these cars to increase the capacity to 100 tons. Many companies produced these, including Pullman, Bethlehem, Evans, Greenville, Trinity and Ortner. The offset side variant of these hoppers carried a little more capacity than their rib-sided cousins.

Road Name History: The Denver & Rio Grande Western Railroad (reporting mark DRGW), often shortened to Rio Grande, D&RG or D&RGW, formerly the Denver & Rio Grande Railroad, was an American Class I railroad company. The railroad started as a 3 ft (914 mm) narrow gauge line running south from Denver, Colorado in 1870. It served mainly as a transcontinental bridge line between Denver, and Salt Lake City, Utah.

In 1988, the Rio Grande's parent corporation, Rio Grande Industries, purchased Southern Pacific Transportation Company, and as the result of a merger, the larger Southern Pacific Railroad name was chosen for identity. The Rio Grande operated as a separate division of the Southern Pacific, until that company was acquired by the Union Pacific Railroad. Today, most former D&RGW main lines are owned and operated by the Union Pacific while several branch lines are now operated as heritage railways by various companies.

Brand/Importer Information: MDC Roundhouse was founded in California in 1938 and relocated in 1993 to Carson City, Nevada due to statewide restrictions on painting. MDC Roundhouse was a producer of both RTR (Ready-to-Run) and kit versions of N Scale rolling stock as well as RTR locomotives. They entered the N scale market in 1979 with a Thrall Hi-Side Gondola and a Hi-Cube Single Door Box Car. MDC Roundhouse was purchased by Horizon Hobbies in June of 2004, when its owner since 1938 C. H. Menteer retired, and merged into their Athearn line.

Unlike many of their contemporaries which contracted with European firms to produce their products, MDC made their own toolings. They made several popular body styles and produced them for road names that many other vendors (even Micro-Trains) wouldn't touch. This made them popular with modelers. Also, their un-assembled "kits" permitted a lower price point so they were popular with "runners" as well as "modelers".

Of particular interest was the attention given to modern 50 foot steel boxcars. They made some attempt to accurately mold the differences into distinct models to represent each of the major prototype manufacturers products. They have distinct toolings not only for the different products from FMC, BFF and PS, but also multiple models for each of these manufacturers including "standard" vs "Youngstown" doors and "waffle" vs. "rib" sides. In total they produced 13 different versions of the 50 foot steel boxcar.
