Micro-Trains - 125 53 029 - Open Hopper, 3-Bay Ortner Rapid Discharge - Western Rail Road - 405

Prototype History: Ortner's team of engineers created the rapid-discharge door system in the early 1960s.. Ortner rapid discharge cars are designed primarily for handling aggregates. They are the best car on the market for this type of commodity. The 60 degree slopes sheets provide for a fast clean unloading of commodities like sand and gravel without using a car shaker. Unfortunately the ARR the gravel season only lasts 4-5 months due to the weather. These cars have a cubic capacity of only about 2,000 cubic feet (plus or minus 10%). So they only can handle 60-65 tons of coal when used in coal service in the winter as much of the ARR fleet started doing when the Seward coal move started. But they weigh nearly as much as a standard hopper so they are not very efficient cars for coal handling.

These cars have long platforms on the ends and a relatively short car body. This is a major pain for loading in motion like is done with the Usibelli tipple and the current gravel terminals in Anchorage. It is really easy to start the loading early or end late in trying to fill the car as full as possible and spilling material on the end platforms. Unloading a train of rapid discharge cars takes 30 minutes to an hour as opposed to four hours or longer for other unloading systems.

Road Name History: This shortline was built in 1976 to connect a quarry and cement mill in the Dittenger - New Brawnfels, Texas area with the mainlines of Missouri Pacific and Missouri-Kansas-Texas just under 2 miles away. Over the years, WRRC operated with a total of four locomotives: two SW1’s, an SW7 and a GP9. Today, the company is owned by Mexican cement giant Cemex and an ES44AC lettered for Cemex can be found doing the switching.

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.
