Specific Item Information: These Denver & Rio Grande Western drop bottom gondolas have been employed in a Maintenance of Way capacity, hauling tunnel forms. Tunnel forms allow cement tunnel walls to be cast in-situ, allowing for a safe, finished tunnel, with fewer production steps and higher overall production speed.
Prototype History: In US railroad terminology, a gondola is an open-topped rail vehicle used for transporting loose bulk materials. All-steel gondolas date back to the early part of the 20th century. Because of their low side walls gondolas are also suitable for the carriage of such high-density cargoes as steel plates or coils, or of bulky items such as prefabricated sections of rail track.
Drop-bottom gondolas were equipped with dump doors that operated via a mechanism located in the center of the car body. The drop bottom door provided a time-saving unloading method compared to the usual, labor-intensive procedure. Instead of equipping workmen with shovels to muck out the car’s content, the lever system was used to open the doors thus immediately dumping the load on the ground. Various commodities could be carried in the drop bottom gons, but coal loadings were most common. Many coaling towers had elevated trestle style delivery ramps where the drop bottom gondolas would be spotted and workmen could simply open the dump doors to spill the contents into the coal bins. At facilities with the elevator bucket style of coal dock, a ramp was used that led up to an open grate where the coal would spill through and into the lower coal bins. The gons were “tailor made” for company service such as dumping ballast directly onto track roadbed during maintenance, as well as hauling cinders out of various engine service facilities. Handy they were!

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: 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.
Manufacturer Information:
Micro-Trains Line split off from Kadee Quality Products in 1990. Kadee Quality Products originally got involved in N-Scale by producing a scaled-down version of their successful HO Magne-Matic knuckle coupler system. This coupler was superior to the ubiquitous 'Rapido' style coupler due to two primary factors: superior realistic appearance and the ability to automatically uncouple when stopped over a magnet embedded in a section of track. The success of these couplers in N-Scale quickly translated to the production of trucks, wheels and in 1972 a release of ready-to-run box cars.
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.
