Model Information: Dating back to 1979, this is the oldest and most popular of Micro-Trains tank cars. Over 200 different regular issues of this body style have been produced as well as hundreds more special runs, including the 2016 N Scale Enthusiast banquet car.

This car models tank cars of approximately 8,000 gallons. The prototypes were built in the 1950's and appeared on freight railroads across the United States and Canada.

Prototype History: Single Dome tank cars are a railroad staple. They have been around since the first half of the 20th century. This length car can handle about 10,000 gallons. These railcars carry a wide array of commodities, including liquid fertilizers, chemicals, fuel oils and asphalt, and food-grade oils. Tank cars can be pressurized or non-pressurized, insulated or non-insulated. Single dome cars carry only a single commodity at once. Food-service tank cars may be lined with stainless steel, glass, or plastic. Tank cars carrying dangerous goods are generally made of different types of steel, depending on the intended cargo and operating pressure. They may also be lined with rubber or coated with specialized coatings for tank protection or product purity purpose. The tank heads are also stronger to prevent ruptures during accidents.

One common version is the ACF Type 27 jacketed tank car with expansion dome which was in common use by many railroads and oil companies.

Road Name History: The Southern Pacific Transportation Company (reporting mark SP), earlier Southern Pacific Railroad and Southern Pacific Company, and usually called the Southern Pacific or (from the railroad's initials) Espee, was an American Class I railroad. It was absorbed in 1988 by the company that controlled the Denver and Rio Grande Western Railroad and eight years later became part of the Union Pacific Railroad.

The railroad was founded as a land holding company in 1865, later acquiring the Central Pacific Railroad by lease. By 1900 the Southern Pacific Company was a major railroad system incorporating many smaller companies, such as the Texas and New Orleans Railroad and Morgan's Louisiana and Texas Railroad. It extended from New Orleans through Texas to El Paso, across New Mexico and through Tucson, to Los Angeles, through most of California, including San Francisco and Sacramento. Central Pacific lines extended east across Nevada to Ogden, Utah, and reached north through Oregon to Portland. Other subsidiaries eventually included the St. Louis Southwestern Railway (Cotton Belt), the Northwestern Pacific Railroad at 328 miles (528 km), the 1,331 miles (2,142 km) Southern Pacific Railroad of Mexico, and a variety of 3 ft (914 mm) narrow gauge routes.

In 1929 SP/T&NO operated 13848 route-miles not including Cotton Belt, whose purchase of the Golden State Route circa 1980 nearly doubled its size to 3,085 miles (4,965 km), bringing total SP/SSW mileage to around 13,508 miles (21,739 km).

By the 1980s route mileage had dropped to 10,423 miles (16,774 km), mainly due to the pruning of branch lines. In 1988 the Southern Pacific was taken over by D&RGW parent Rio Grande Industries. The combined railroad kept the Southern Pacific name due to its brand recognition in the railroad industry and with customers of both constituent railroads. Along with the addition of the SPCSL Corporation route from Chicago to St. Louis, the total length of the D&RGW/SP/SSW system was 15,959 miles (25,684 km).

By 1996 years of financial problems had dropped SP's mileage to 13,715 miles (22,072 km), and it was taken over by the Union Pacific Railroad.

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.
