Micro-Trains - 027 00 510 - Boxcar, 50 Foot, Steel, Plug Door - Tetra Tech - 001

Specific Item Information: This Tetra Tech “RailAI” track geometry inspection car is automated and outfitted with various sensors to examine track conditions such as position, curvature, alignment, smoothness, track gauge, as well as defects such as incorrect rail profile, rail warp, and other parameters. It can then record and transmit this data in detail and mark areas needing repair or adjustment.

Model Information: Introduced in September of 1983 with ATSF 151900 and 151951, Micro-Trains has produced 83 different versions of this car (as of March, 2016). Body style 027 represents a 50 foot prototype "Plug" single-door Box Car. Unlike the "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.

Unfortunately for collectors, this means that in order to accurately portray the prototype, this body style does not feature doors that actually open. All other hallmark features of Micro-Trains quality are present. This includes high quality tooling, crisp printing and the ubiquitous knuckle coupler.

Prototype History: The 50-foot boxcar made its first appearance in the 1930s and steadily grew in popularity over the years, which further improved redundancies by allowing for even more space within a given car. Today, the 50-footer remains the common boxcar size. After the second world war ended, and steel became once again readily available, steel became the go-to choice for construction of boxcars. Pullman Standard and ACF were some of the most prolific builders of these cars.

In the 1960s, the flush, "plug" style sliding door was introduced as an option that provides a larger door to ease loading and unloading of certain commodities. The tight-fitting doors are better insulated and allow a car's interior to be maintained at a more even temperature.

Road Name History: Tetra Tech is a premier worldwide consulting and engineering firm, focusing on water, environment, sustainable infrastructure, renewable energy, and international development.

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.
