Specific Item Information: These 50’ airslide hoppers are grey with black lettering and run on 100-Ton Barber Roller Bearing trucks. Built in 1976 as part of series 310580-310699, these cars had a special epoxy lining that was specifically designed for use with fine-grained commodities, like powdered sugar, that could settle en-route making unloading difficult.
Prototype Information: The Airslide hopper was first patented in 1953. What made the car unique was a set of fabric membranes in the hopper bays. Made of tightly woven cotton and treated with silicone, the Airslide B membranes were moisture-proof, but allowed air to pass through. Compressed air was supplied at the unloading site and passed through the membrane up into the load. This aerated the load, allowing it to flow easily through the hoppers. Tests showed that the Airslide hoppers Could be unloaded as much as twice as fast as Conventional hoppers.
GATX produced the 4180 cf Airslide covered hoppers between 1963 and 1980 providing customers with an innovative way to load and unload product quickly via air pressure. The unusual box car style design for this hopper allowed for more interior volume than standard hoppers of equal size. Three variations of the body were built, this GACX car represents the post 1973 design and proved rugged enough to be in service today.
The Santa Fe was a pioneer in intermodal freight transport, an enterprise that (at one time or another) included a tugboat fleet and an airline (the short-lived Santa Fe Skyway). Its bus line extended passenger transportation to areas not accessible by rail, and ferryboats on the San Francisco Bay allowed travelers to complete their westward journeys to the Pacific Ocean. The ATSF was the subject of a popular song, Harry Warren & Johnny Mercer's "On the Atchison, Topeka and the Santa Fe", written for the film, The Harvey Girls (1946).
The railroad officially ceased operations on December 31, 1996, when it merged with the Burlington Northern Railroad to form the Burlington Northern & Santa Fe Railway.

Brand/Importer Information: Micro-Trains is the brand name used by both Kadee Quality Products and Micro-Trains Line. For a history of the relationship between the brand and the two companies, please consult our Micro-Trains Collector's Guide.
Micro-Trains Line Co. split off from Kadee in 1990 to form a completely independent company. For this reason, products from this company can appear with labels from both enterprises. Due to the nature of production idiosyncrasies and various random factors, the rolling stock from Micro-Trains can have all sorts of interesting variations in both their packaging as well as the products themselves. When acquiring an MTL product it is very important to understand these important production variations that can greatly enhance (or decrease) the value of your purchase.
