Roundhouse - 84403 - Tank Car, Single Dome, 50 Foot - Tank Train - 15699

Model Information: This is a fairly nice quality tank car from MDC Roundhouse. It likely first appeared in the late 1980s. It appears to model a general service tank car and the road names and paint schemes seem to suggest this is what MDC had in mind. The Roundhouse models were available in both kit and RTR packaging. It doesn't have a ton of detail. Most versions were released with Rapido Couplers so it therefore qualifies as a late 1st generation model. Nevertheless, once the couplers are swapped out, it will look just fine on even the most modern of layouts due to the high print quality and molding on this model. Like all other N Scale toolings made by MDC Roundhouse, this one was acquired by Athearn in 2006. Eastern Seaboard Models has also sold these in custom paint schemes.

Prototype History: Larger, 50' Tank cars replaced their smaller predecessors in the late 1960s and 1970s. The Richmond Tank Car Company was one of several manufacturers to produce these general purpose railcars. They generally had about 20,000 gallon capacity and were used to transport many different commodities.

Road Name History: General American's TankTrain system of interconnecting tank cars provides shippers with a quick and cost-effective method of moving large volumes of bulk liquids. The TankTrain system consists of an entire string of cars that can be loaded or unloaded from a single System connection. The last car in each set (of 12 cars) is left 3/4 full. Then nitrogen gas (non-flammable, non-toxic) is used to purge the loading lines of any remaining oil which fills the last car.

The TankTrain System was first tested by the Alaska Railroad. The ARR purchased two sets of three that were linked together. They didn't stay that way though and eventually wound up as individual cars. Some ARR crew members felt they were more bother than they were worth. The cars had to be kept turned in a certain direction which wasn't always operationally easy. If one car was Bad Ordered then the whole string had to go in the shop. The ARR ceased using them in the late 1970s and they were all shipped to the lower 48. A much updated version of the TankTrain was later fielded for the Southern Pacific "Oilcan" that went from central California, over Tehachapi Pass, to Los Angeles. Later, the run went from Mojave to L.A.,

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.
