Micro-Trains - 74000 - Boxcar, 40 Foot, Steel Plug Door - Dimensional Data - n/a

Model Information: Model: Introduction: July 1996. This body style (074) has no roof walk and short ladders.

Unlike the traditional "sliding" door, the plug door system closes with a final inward movement (similar to most van sliding doors) that seals the door flush with the interior of the boxcar. This provides a much better seal than the sliding door boxcar. A rotating lever on the door activates a gear system to "plug" and "unplug" the door.

Prototype History: Plug-Door boxcars are usually insulated and typically carry products such as canned goods that require protection from extremes of temperature but do not require refrigeration. Plug-style doors were normally used to ensure a tight seal in the insulation. Designed for transport of both perishables and large loads, plug doors allowed box cars to be sealed from outside dust and dirt. Cars like these were manufactured during the 50s and 60s.

Whether you consider this a reefer or a boxcar is a matter for angel-pinhead-counters. There seems to be a bit of a blurry line during the transition era between the idea of a steel ice reefer and an insulated boxcar. I guess an ice reefer was meant to hold ice for cooling but I doubt this is a cut-and-dry distinction. Modern "mechanical" reefers are a different breed as they contain a refrigeration unit which quite distinctly sets them apart from "boxcars".

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: 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.
