Specific Item Information: with Nose Headlight

Body Style 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.

DCC Information: Models accept the following plug-in decoders:
- Digitrax DN163K1C: 1 Amp N Scale Mobile Decoder for Kato N scale SD40-2 locos made from year 2006 onward.
- Digitrax SDN144K1E: 1 Amp N Scale SoundFX/Mobile/FX3 Function Decoder for Kato SD40-2 and similar locos.
- TCS K1D4: 4 Function Drop-In for Kato N-Scale EMD SD40, EMD SD70MAC, EMD SD70/75M, GE C44-9W, GE AC4400W, Athearn F45.
- TCS K1D4-NC: 4 Function Drop-In for Kato N-Scale EMD SD70ACe, EMD SD70M, EMD SD40-2, and GG1.
- MRC 1644-2: N-Scale Sound Decoder for Kato SD70MAC & AC4400
- MRC 1960: N-Scale Sound Decoder for Kato SD45/SD70MAC/AC4400

Prototype Information: The EMD SD70 is a series of diesel-electric locomotives produced by Electro-Motive Diesel in response to the GE Dash 9-44CW. Production commenced in late 1992 and since then over 4,000 units have been produced; most of these are the SD70M and SD70MAC models. All locomotives of this series are hood units with C-C trucks.

Prior to the SD70ACe and SD70M-2 models, all SD70 models were delivered with the self-steering HTCR radial truck. The radial truck allows the axles to steer in curves which reduces wear on the wheels and railhead. With the introduction of the SD70ACe and SD70M-2 models, EMD introduced a new bolsterless non-radial HTSC truck as the standard truck for these models in an effort to reduce costs. The HTCR-4 radial truck is still an option.

All SD70ACe and SD70M-2 locomotives are, from the factory, equipped with one Nathan Airchime K5LLA-R1L airhorn mounted on a high-profile base. Due to height clearance restrictions, production models of the SD70ACe-T4 will be equipped with one K5LLA airhorn, mounted on a low-profile base, facing forward, and one "dual tone" K-13B airhorn, mounted over the rear headlight, facing rearward.

From Wikipedia

Road/Company Information:
The Alaska Railroad (reporting mark ARR) is a Class II railroad which extends from Seward and Whittier, in the south of the state of Alaska, in the United States, to Fairbanks (passing through Anchorage), and beyond to Eielson Air Force Base and Fort Wainwright in the interior of that state. Uniquely (for the US), it carries both freight and passengers throughout its system, including Denali National Park. The railroad has a mainline over 470 miles (760 km) long and is well over 500 miles (800 km) including branch lines and siding tracks. It is currently owned by the state of Alaska. The railroad is connected to the lower 48 via three rail barges that sail between the Port of Whittier and Harbor Island in Seattle (the Alaska Railroad-owned Alaska Rail Marine, from Whittier to Seattle, and the CN Rail-owned Aqua Train, from Whittier to Prince Rupert, British Columbia) but does not currently have a direct, land-based connection with any other railroad lines on the North American network. In 2013, the company earned a profit of $14.3 million (up 14%) on revenues of $175.1 million (down 1%), $165.6 million of which was operating revenue (down 2%).

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.)
