Specific Item Information: Straight Radiator

Model Information: Kato introduced the SD70 model in 2003. The first version was the SD70MAC. They followed up in 2005 with the SD70M. In 2006 they added the 'Flat Radiator' SD70M version. In 2009 they introduced the SD70ACe and revised the SD70M. All versions of this model share the same internal mechanism and only show minor differences in the shell. The internal mechanism was heavily revised/evolved in the 2009 release.

The revised versions are typical modern Kato release with a split-frame design, dual flywheels, chemically-blackened wheels and up-gradable to DCC with a drop-in decoder. They pull well and run quietly. The have very nice details like separately applied (rather than molded) hoses. Due the the 6-axle configuration, they do not run well in curves of less than 11 inches.

- Digitrax DN163K1C: 1 Amp N Scale Mobile Decoder for Kato N scale SD40-2 locos made from year 2006 onward.

Prototype History: The EMD SD70 is a series of high-powered, single engined 4,000hp to 4,300hp, diesel-electric locomotives produced by Electro-Motive Division (EMD). All locomotives of this series are hood units with C-C trucks. Production commenced in late 1992 and since then over 4,000 units have been produced. The most produced models of the series are the SD70M, SD70MAC and SD70ACe models. All SD70 models were delivered with the self-steering radial truck HTCR , then from SD70ACe and SD70M-2 models, with non-radial HTSC truck. The radial truck allows the axles to steer in curves which reduces wear on the wheels and railhead.

The SD70ACe AC-traction diesel locomotive (most in the industry simply call them SD70 "Ace" or "Aces") is the successor to the older SD70MAC. It was first introduced in 2004, and has been in production since 2005. It was originally designed to comply with EPA Tier 2 locomotive emissions regulations. Beginning in 2012, newly built SD70ACe's were EPA Tier 3 compliant. SD70ACes are equipped with EMD's 16-710-G3C-T2 prime mover, rated at 4,300 horsepower (3,200 kW); later Tier 3 models are rated at 4,500 horsepower (3,400 kW). The model is still in production as EMD's primary long-haul domestic locomotive.

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: KATO U.S.A. was established in 1986, with the first U.S. locomotive model (the GP38-2, in N-Scale) released in 1987. Since that time, KATO has come to be known as one of the leading manufacturers of precision railroad products for the modeling community. KATO's parent company, Sekisui Kinzoku Co., Ltd., is headquartered in Tokyo, Japan.

In addition to producing ready-to-run HO and N scale models that are universally hailed for their high level of detail, craftsmanship and operation, KATO also manufactures UNITRACK. UNITRACK is the finest rail & roadbed modular track system available to modelers today. With the track and roadbed integrated into a single piece, UNITRACK features a nickel-silver rail and a realistic-looking roadbed. Patented UNIJOINERS allow sections to be snapped together quickly and securely, time after time if necessary.

The Kato U.S.A. office and warehouse facility is located in Schaumburg, Illinois, approximately 30 miles northwest of Chicago. All research & development of new North American products is performed here, in addition to the sales and distribution of merchandise to a vast network of wholesale representatives and retail dealers. Models requiring service sent in by hobbyists are usually attended to at this location as well. The manufacturing of all KATO products is performed in Japan.

Supporters of KATO should note that there is currently no showroom or operating exhibit of models at the Schaumburg facility. Furthermore, model parts are the only merchandise sold directly to consumers. (Please view the Parts Catalog of this website for more specific information.)
