Model Information: The Atlas GP7, GP9 and GP9-TT models are some of their oldest models. The models share the same internal mechanisms and differ only in their shell details. Unlike many of their other older body styles, these bodies have been updated several times and are still a regular part of the Atlas production cycle.
The first release of this body type was in 1974 and the models were produced by Roco in Austria. Production for these models ended in 1982. The next release started in 1987 and the models were re-tooled by Kato in Japan for Atlas. The third version came out in 1995 and was made in China for Atlas and these engines were essentially a redo of the Kato mechanism. Finally, in 2006, a completely new mechanism was introduced and this 4th version is a split frame, dual-flywheel, slow-motor, modern engine. Furthermore, with the more recent releases, most road-names and numbers are available in both a DCC-Ready and a Decoder-Equipped version.
Assembly instructions from Atlas: GP7 (Japan version), GP7 Ph.1 (China version), GP7 Ph.2 (China version).

DCC Information: The first version of this engine (Roco) gets a solid "No" for DCC capability, but this is no surprise as these were made in 1974. The next two releases (Kato and China) are split-frame, but also split-board. They may be DCC-Friendly, but likely it will be a fair amount of work to upgrade these. The most recent version (China, 2006+) is eminently DCC-Ready. Furthermore, most road-names and numbers produced since 2006 are available in both a DCC-Ready and a Decoder-Equipped version. Earlier DCC factory-equipped versions were fitted with Lenz LE063XF decoders, whereas most recent versions are fitted with NCE N12A2 decoders. The Atlas version of these decoders will respond to manufacturer's address "127" (CV8) i.e. "Atlas Model Railroad Products", though being identical to their original manufacturer's specification.
For non-DCC-ready versions, a wired DCC decoder installation for this model can be found on Brad Myers' N-scale DCC decoder installs blog.
Models produced since 2006 accept the following plug-in decoders:
- Digitrax DN163A4: 1.5 Amp N Scale Board Replacement Mobile Decoder for Atlas GP30 and other short Atlas diesel locomotives.
- Digitrax DN163A2: Retired decoder, replaced by DN163A4.
- NCE N12A2: Plug and play decoder for N-Scale Atlas Classic Series GP7, GP9, GP30, GP35.
- TCS ASD4 (Installation for GP7, Installation for GP9)
- MRC 1955: N-Scale Sound Decoder for Atlas GP-7, GP-9, GP-30 or GP-35

Prototype History: 
The EMD GP7 is a four-axle (B-B) road switcher diesel-electric locomotive built by General Motors Electro-Motive Division and General Motors Diesel between October 1949 and May 1954. Power was provided by an EMD 567B 16-cylinder engine which generated 1,500 horsepower (1,119 kW). The GP7 was offered both with and without control cabs, and those built without control cabs were called a GP7B. Five GP7B's were built between March and April 1953. The GP7 was the first EMD road locomotive to use a hood unit design instead of a car-body design. This proved to be more efficient than the car body design as the hood unit cost less to build, was cheaper and easier to maintain, and had much better front and rear visibility for switching.
Of the 2,734 GP7's built, 2,620 were for American railroads (including 5 GP7B units built for the Atchison, Topeka and Santa Fe Railway), 112 were built for Canadian railroads, and 2 were built for Mexican railroads. This was the first model in EMD's GP (General Purpose) series of locomotives. Concurrently, EMD offered a six-axle (C-C) SD (Special Duty) locomotive, the SD7.

Road Name History: 
The St. Louis Southwestern Railway (reporting mark SSW), known by its nickname of "The Cotton Belt Route" or simply Cotton Belt, is a former US Class I railroad which operated between St. Louis, Missouri, and various points in the states of Arkansas and Texas from 1891 to 1992.
The Cotton Belt was one of the lines comprising the railroad empire acquired by financier Jay Gould in the last quarter of the 19th century; according to the Handbook of Texas, By 1890 Gould owned the Missouri Pacific, the Texas and Pacific, the St. Louis Southwestern, and the International-Great Northern, one-half of the mileage in the Southwest.
The railroad was organized on January 15, 1891, although it had its origins in a series of short lines founded in Tyler, Texas, in 1870 that connected northeastern Texas to Arkansas and southeastern Missouri. Construction of the original Tyler Tap Railroad began in the summer of 1875.
On October 18, 1903, the Cotton Belt gained trackage rights via the Thebes Bridge and the Missouri Pacific Railroad along the eastern shore of the Mississippi River to reach East St. Louis, Illinois, and then used Terminal Railroad Association trackage rights into St. Louis. The Cotton Belt also operated a yard and a locomotive servicing facility in East St. Louis, just east of Valley Junction, and south of Alton and Southern Railroad's Gateway Yard, and north of Kansas City Southern's East St. Louis Yard. They also had a freight station in downtown St. Louis. Union Pacific Railroad now operates the yard (still named "Cotton Belt Yard"), but the engine servicing facilities have been demolished.
The Cotton Belt and subsidiary St. Louis Southwestern Railway of Texas together operated 1,607 miles of road in 1945; 1,555 miles in 1965; and 2,115 miles in 1981 after taking over the Rock Island's Golden State Route. In 1925 SSW and SSW of Texas reported a total of 1474 million net ton-miles of revenue freight and 75 million passenger-miles; in 1970 it carried 8650 million ton-miles and no passengers.
The Southern Pacific Company gained Interstate Commerce Commission approval to control the Cotton Belt system on April 14, 1932, but continued to operate it as a separate company until 1992, when the SP consolidated the Cotton Belt's operations into the parent company. Cotton Belt diesel locomotives from 1959 on were painted in Southern Pacific's "bloody nose" scheme - dark gray locomotive body with a red "winged" nose. "Cotton Belt" was painted on the sides and in later years the letters "SSW" were painted on the nose.
In 1996 the Union Pacific Railroad finished the acquisition that was effectively begun almost a century before with the purchase of the Southern Pacific by UP in 1901, until divestiture was ordered in 1913. The merged company retains the name "Union Pacific" for all railroad operations. Many former SSW locomotives are used by Union Pacific today, although few still sport unmodified "Cotton Belt" paint. Most of the remaining units have been repainted into the UP scheme, while others wear patched SSW paint with a UP shield logo and new numbers applied over the SSW number.

In 1924 Stephan Schaffan, Sr. founded the Atlas Tool Company in Newark, New Jersey. In 1933 his son, Stephan Schaffan, Jr., came to work for his father at the age of sixteen. Steve Jr. built model airplanes as a hobby and frequented a local hobby shop. Being an enterprising young man, he would often ask the owner if there was anything he could do to earn some extra spending money. Tired of listening to his requests, the hobby-store owner threw some model railroad track parts his way and said, "Here, see if you can improve on this".
In those days, railroad modelers had to assemble and build everything from scratch. Steve Jr. created a "switch kit" which sold so well, that the entire family worked on them in the basement at night, while doing business as usual in the machine shop during the day.
Subsequently, Steve Jr. engineered the stapling of rail to fiber track, along with inventing the first practical rail joiner and pre-assembled turnouts and flexible track. All of these products, and more, helped to popularize model railroading and assisted in the creation of a mass-market hobby. The budding entrepreneur quickly outgrew the limitations of a basement and small garage operation. Realizing they could actually make a living selling track and related products, Steve and his father had the first factory built in Hillside, New Jersey at 413 Florence Avenue in 1947. On September 30, 1949, the Atlas Tool Company was officially incorporated as a New Jersey company.
In 1985, Steve was honored posthumously for his inventions by the Model Railroad Industry Association and was inducted into the Model Railroad Industry Hall of Fame in Baltimore, Maryland. In addition, Steve was nominated and entered into the National Model Railroad Association Pioneers of Model Railroading in 1995.
In the early 1990s, the Atlas Tool Company changed its name to Atlas Model Railroad Company, Inc.
