AHM - 4368 - Open Hopper, 4-Bay Steel - Kansas Okahoma & Gulf - 835

Model Information: Roco made 2 different 4-bay open hopper N Scale models in the late 1960s/early 1970s. This one is the rib-side version and the other one is an offset side. At first glance, it is fairly easy to confuse the two. The rib-side versions were made for AHM specifically and were stamped 'AHM Austria' on the bottom. They were later imported for a brief time by another company called JC Timmer in CP paint schemes. Walthers also imported these with Roco branded boxes. I have to assume that the stamping on the JC Timmer and Roco versions do NOT say 'AHM Austria' on the bottom.

Overall it is a pretty nice tooling for its time. The molded details are quite fine and even include rivet patterns on the interior. I have seen 3rd generation models with less detail inside the cargo area. The AHM versions have blackened metal wheels whereas the JC Timmer and Roco versions have nickel-silver plated wheels. The couplers are truck mounted (no surprise given the age of this tooling).

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 Kansas, Oklahoma and Gulf Railway (reporting mark KOG) (KO&G) was formed on July 31, 1919 from the assets of the bankrupt Missouri, Oklahoma and Gulf Railway. The KO&G largely consisted of a single line from Baxter Springs, Kansas, to Denison, Texas, prior to its purchase by Missouri Pacific's Texas and Pacific Railway in 1964 and merger in 1970.

The KO&G owed much of its latter existence to its status as a bridge line between the Missouri Pacific at Okay, Oklahoma and the Missouri Pacific-controlled Texas and Pacific Railway at Denison, Texas. This traffic was the main source of revenue for the KO&G and was the primary reason that the MP acquired it. The KO&G came under common control of the Muskogee Company (often referred to as the "Muskogee Roads" or the "Muskogee Lines") in 1925, sharing common management with the Midland Valley Railroad and the Oklahoma City-Ada-Atoka Railway from 1930 to 1964. In 1967 KO&G operated 209 miles of railroad and reported 457 million ton-miles of revenue freight.

Brand/Importer Information:

AHM is the initials for Associated Hobby Manufacturers, Inc. The company was founded in 1959 as a reseller of other companies' model railroad components. Initially an HO company, they entered into N Scale in the early 1970's as an importer of products made by Roco in Austria. For N Scale products, AHM apparently contracted to use the exact same molds as were used by Roco to produce early Atlas models. They also contracted with Rivarossi to make locomotives.

When AHM went out of business IHC picked up some of their line. Also, at least one body style was taken over by Eastern Seaboard models.
