Micro-Trains - 46000 - Gondola, 50 Foot, Steel - Dimensional Data - n/a

Model Information: This model is one of Micro-Trains' earliest releases. It was first produced in 1975 with Dimensional Data, and the following year in several different paint schemes. It models a 50 foot steel gondola with a fishbelly and drop-ends. Note that many 3rd party loads designed for MTL's fix-end gondola will not fit in this model. What is cool is that the ends can actually be dropped! This feature makes this model unique among N Scale gondola toolings.
This model is equipped with National B-1 Trucks w. short extension (MTL 003 02 151 (1195)) and one end and w. medium extension on the other end.

Prototype History: In US railroad terminology, a gondola is an open-topped rail vehicle used for transporting loose bulk materials. Because of their low side walls, gondolas are also suitable for the carriage of such high-density cargoes as steel plates, steel coils, and bulky items such as prefabricated sections of rail track. For weather-sensitive loads, these gondolas are often equipped with covers.

All-steel gondolas date back to the early part of the 20th century. However, most of the early ones were shorter and used 40' designs. The ubiquitous 50' steel gondola we see modeled so often today are typical of railcars produced since the end of the second world war. In the late 1940s, steel became once again readily available and new, longer gondolas were produced to transport material for America's booming economy. Generally, these 50 foot cars have a capacity of 70 tons and were actually 52'6" long. The first models of this design were produced by the Erie Railroad and the Greenville Steel Car Co, but nearly identical cars were produced by Pullman, ACF and Bethlehem.

Road Name History: "Dimensional Data" here means painted models with printed body specifications and no road/reporting letters/marks or road Name/livery. The data typically consists of internal and external dimensions, capacities, weight information and specific characteristics of freight cars, trailers and containers.

The Association of American Railroads (AAR) sets standards for the uniform marking of freight cars with regard to car ownership, weight, load capacity, dimensions, and maintenance. In addition, car owners choose to display data relating to various devices and equipment so the cars may be properly used and repaired.

CAPY (nominal capacity) is the intended load-carrying capacity of the car, to the nearest 1000 pounds. This is determined by the structural strength of the car's underframe and the size of the journal bearings of the car's trucks.

LD LMT (load limit) is the maximum weight of lading that can be carried by the car, to the nearest 100 pounds. This is determined by subtracting the weight of the car when empty from the total allowable gross weight given the size of the car's journal bearings. The load limit for a car is usually a bit greater than its capacity; the two figures can be equal, but capacity can never exceed load limit.

LT WT (light, or empty, weight) is the weight of the car when empty. Accompanying the light weight marking is a date indicating when the railroad or owner last verified the car's weight. The letters for this mark are not always reporting marks; sometimes a location code is used. NEW and a date indicates that the weight shown is the car's as-built weight, and that it hasn't been field-checked since.

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: 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.
In October 1990 Kadee separated in two companies, with the newly created Micro-Trains® Line Co. continuing the Z, Nn3, and N Scale product ranges, with Kadee retaining the HO range.
