Roundhouse - 8620 - Open Hopper, 3-Bay, 70 Ton Offset - Undecorated

Model Information: This body style was created by MDC Roundhouse and acquired by Athearn. The older MDC releases have Rapido couplers (the final few MDC releases included dummy knuckle couplers in the packaging) and the AThearn releases use Accumate or McHenry operating magnetic knuckle couplers.

Prototype History: 70 ton 3-bay offset side hoppers first appeared in the late 20s and by the late 30s had become an AAR standard design with cars being delivered from a number of builders in large quantities to railroads across the country. The last of these cars were delivered in the mid-'60s and many remained in service through the 80s.

Road Name History: Although they may be molded in color, unpainted and unlettered, undecorated products are marketed to modelers who seek to custom decorate their models for private roads and/or road and/or company names that were not commercially produced by any of the major manufacturers.

Undecorated models are frequently also unassembled or only partially assembled and required modelers to be comfortable with glue, paint and sometimes solder in order to prepare their models for display. Materials for these models can vary but often include plastic, pewter and resin. Models may or may not come with decals or other decorations such as plastic signage, railings and ladders to enhance the appearance of the final product.

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.
