Model Information: Athearn introduced the SD70M and SD75M in 2005. They followed up in 2006 with the SD70I and SD75I. All four versions share the same mechanism and apart from minor difference all four have similar shells as well. The model was developed for Athearn in Korea by Ajin.

Unlike Ajin's earlier F59PHI, these models are modern, well-behaved model engines. They have split-frame dual-flywheel chassis with a 3-pole motor. The detail and engine performance are on par with modern Atlas and Kato products. They also feature some pretty cool cab detail which sets them apart from the competing products from Atlas and Kato.

DCC Information: The DCC friendliness, at least for the early versions of this model, really blows. Despite the split-frame design, I would qualify the upgrade process as "a bear". . Definitely a caveat emptor type of thing. Some of the later versions are truly DCC-Ready, but there is no clear cut-off date or model number. You just have to take the shell off and look inside. Later "drop-in capable" models will accept a Digitrax lightboard: the DN163K1C

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 Norfolk Southern Railway (reporting mark NS) is a Class I railroad in the United States; began in 1982 and 1990. With headquarters in Norfolk, Virginia, the company operates 36,200 route miles in 22 eastern states, the District of Columbia, and has rights in Canada from Buffalo to Toronto and over the Albany to Montreal route. NS is responsible for maintaining 29,000 miles, with the remainder being operated under trackage rights from other parties responsible for maintenance. The common commodity hauled on the railroad is coal from mines in Indiana, Kentucky, Pennsylvania, Tennessee, Virginia, and West Virginia. The railroad also offers the most intermodal network in eastern North America.

NS is a major transporter of domestic and export coal. The railroad's major sources of the mineral are located in: Pennsylvania's Cambria and Indiana counties, as well as the Monongahela Valley; West Virginia; and the Appalachia regions of Virginia, Kentucky, and Tennessee. In Pennsylvania, NS also receives coal through interchange with R.J. Corman Railroad/Pennsylvania Lines at Cresson, Pennsylvania, originating in the "Clearfield Cluster". NS's export of West Virginia bituminous coal, begins transport on portions of the well-engineered former Virginian Railway and the former N&W double-tracked line in Eastern Virginia to its Lambert's Point coal pier on Hampton Roads at Norfolk. Coal transported by NS is thus exported to steel mills and power plants around the world. The company is also a major transporter of auto parts and completed vehicles. It operates intermodal container and TOFC (trailer on flat car) trains, some in conjunction with other railroads. NS was the first railway to employ roadrailers, which are highway truck trailers with interchangeable wheel sets.

The Norfolk Southern Railway's parent Norfolk Southern Corporation is a Norfolk, Virginia-based parent company. Norfolk Southern Corporation was incorporated on July 23, 1980 in the Commonwealth of Virginia and is publicly traded on the New York Stock Exchange (NYSE) under the symbols NSC. The primary business function of Norfolk Southern Corporation is the rail transportation of raw materials, intermediate products, and finished goods across the Southeast, East, and Midwest United States. The corporation further facilitates transport to the remainder of the United States through interchange with other rail carriers while also serving overseas transport needs by serving several Atlantic and Gulf Coast ports. As of October 1, 2014 Norfolk Southern Corporation's total public stock value was slightly over $34.5 billion.

Brand/Importer Information:
Athearn's history began in 1938, when its founder-to-be, Irvin Athearn, started an elaborate O scale layout in his mother's house. After placing an ad selling the layout, and receiving much response to it, Irv decided that selling model railroads would be a good living. He sold train products out of his mother's house through most of the 1940s. After becoming a full-time retailer in 1946, Irv opened a separate facility in Hawthorne, California in 1948, and that same year he branched into HO scale models for the first time.

Athearn acquired the Globe Models product line and improved upon it, introducing a comprehensive array of locomotive, passenger and freight car models. Improvements included all-wheel drive and electrical contact. One innovation was the "Hi-Fi" drive mechanism, employing small rubber bands to transfer motion from the motor spindle to the axles. Another was the double-ended ring magnet motor, which permitted easy connection to all-wheel-drive assemblies. Athearn was also able to incorporate flywheels into double-ended drives.

The company produced a model of the Boston & Maine P4 class Pacific steam locomotive which incorporated a cast zinc alloy base and thermoplastic resin superstructure. It had a worm drive and all power pickup was through the bipolar trucks that carried the tender. This item was discontinued after the Wilson motor was no longer available, and was not redesigned for a more technologically advanced motor.

Athearn's car fleet included shorter-than-scale interpretations of passenger cars of Southern Pacific and Atchison, Topeka & Santa Fe Railroad prototypes. The company also offered a variety of scale-length freight cars with sprung and equalized trucks. The cars could be obtained in simple kit form, or ready-to-run in windowed display boxes. The comprehensive scope of the product line contributed to the popularity of HO as a model railroad scale, due to the ready availability of items and their low cost.

Irv Athearn died in 1991. New owners took control in 1994, but continued to follow Athearn's commitment to high-quality products at reasonable prices. Athearn was bought in 2004 by Horizon Hobby. Athearn was then moved from its facility in Compton to a new facility in Carson, California. In mid-2009, all remaining US production was moved to China and warehousing moved to parent Horizon Hobby. Sales and product development was relocated to a smaller facility in Long Beach, California.
