Athearn - 3088 - Locomotive, Diesel, EMD SD70 - Illinois Central - 1001

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.
Although mechanically similar to earlier SD70 units, the SD70ACe rides on a new underframe and uses mostly new sheet metal above the frame. Electrical cables and air lines have been routed beneath the walkways on opposite sides, allowing easier access for maintenance. Continuing the designs of the SD80 and SD90 series, the radiator on the locomotive is nearly as wide as the cab, the center hood section is a step down below the roofline, and the dynamic brakes have been moved to the rear of the hood. The SD70ACe uses the cab design of late-model SD90MAC-H units, which uses rectangular window glass and is externally different from the two cab variations used on earlier SD70M and SD70MAC units. In 2008, EMD standardized the isolated cab on subsequent SD70ACes after non-isolated cab units were restricted from leading on BNSF Railway due to excessive cab vibration. Purchasers included ArcelorMittal, BNSF Railway, Canadian National Railway, CSX Transportation, Ferromex, Kansas City Southern Railway, Montana Rail Link, Norfolk Southern Railway, CVG Ferrominera Orinoco, Union Pacific Railroad, Quebec North Shore and Labrador Railway, BHP Billiton, and shortline Arkansas and Missouri Railroad.

Road Name History: The Illinois Central Railroad (reporting mark IC), sometimes called the Main Line of Mid-America, was a railroad in the central United States, with its primary routes connecting Chicago, Illinois, with New Orleans, Louisiana, and Mobile, Alabama. A line also connected Chicago with Sioux City, Iowa (1870). There was a significant branch to Omaha, Nebraska (1899), west of Fort Dodge, Iowa, and another branch reaching Sioux Falls, South Dakota (1877), starting from Cherokee, Iowa. The Sioux Falls branch has been abandoned in its entirety.

The IC is one of the early Class I railroads in the US. Its roots go back to abortive attempts by the Illinois General Assembly to charter a railroad linking the northern and southern parts of the state of Illinois. In 1850 U.S. President Millard Fillmore signed a land grant for the construction of the railroad, making the Illinois Central the first land-grant railroad in the United States.

The Illinois Central was chartered by the Illinois General Assembly on February 10, 1851. Senator Stephen Douglas and later President Abraham Lincoln were both Illinois Central men who lobbied for it. Douglas owned land near the terminal in Chicago. Lincoln was a lawyer for the railroad. Upon its completion in 1856 the IC was the longest railroad in the world. Its main line went from Cairo, Illinois, at the southern tip of the state, to Galena, in the northwest corner. A branch line went from Centralia, (named for the railroad) to the rapidly growing city of Chicago. In Chicago its tracks were laid along the shore of Lake Michigan and on an offshore causeway downtown, but land-filling and natural deposition have moved the present-day shore to the east.

In 1867 the Illinois Central extended its track into Iowa, and during the 1870s and 1880s the IC acquired and expanded railroads in the southern United States. IC lines crisscrossed the state of Mississippi and went as far as New Orleans, Louisiana, to the south and Louisville, Kentucky, in the east. In the 1880s, northern lines were built to Dodgeville, Wisconsin, Sioux Falls, South Dakota, and Omaha, Nebraska. Further expansion continued into the early twentieth century.

The Illinois Central, and the other "Harriman lines" owned by E.H. Harriman, was the target of the Illinois Central shopmen's strike of 1911. Although marked by violence and sabotage in the south, midwest, and western states, the strike was effectively over in a few months. The railroads simply hired replacements and withstood diminishing union pressure. The strike was eventually called off in 1915.

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.
