Prototype History: The plug-and-sliding-door or combo-door boxcar is a versatile car that can act as either a double door boxcar or a plug door boxcar. If you were loading 8' studs in the car, you would load the car just like any other double door boxcar. But if you are loading paper, you would seal the far doors with duct tape, load the car and close the slider. Seal the slider with duct tape, and then shut the plug door to seal the car.
The main reason all the large box cars today have mostly plug doors, is that large sliding doors just get too hard to move. Trying to open regular 8' sliding doors, unless the cars were fairly new, is quite challenging. After a sliding-door car was several years old, you'd see where the sliding door was getting all banged up from people using forklift blades to open and close the doors. Plug doors, however, run on wide runners and rollers, and are therefore easier to move. Also, since the doors are out away from the car side, there is no problem when a car side becomes bulged out due to wear and tear.

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-TrainsĀ® Line Co. continuing the Z, Nn3, and N Scale product ranges, with Kadee retaining the HO range.
