Model Information: The Atlas GP7, GP7-TT, GP9 and GP9-TT models are some of Atlas' oldest models. The four locomotives 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.
Given their long history of releases, these models come in a plethora of different versions. 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 Kato version re-used the same mechanism as was used in the earlier RS3. It doesn't work as well in the Geep. The third version was made in China for Atlas and these engines were essentially a redo of the Kato mechanism (with all the faults). Finally, in 2006, the mechanism was redone properly and this 4th version is a properly DCC-Ready split frame, slow-motor modern engine.
Assembly instructions from Atlas: GP9 (Japan version), GP9 Ph.2 (China version), GP9 Torpedo Tube.

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.

Prototype History: 
An EMD GP9 is a four-axle diesel-electric locomotive built by General Motors' Electro-Motive Division in the United States, and General Motors Diesel in Canada between January, 1954, and August, 1963. US production ended in December, 1959, while an additional thirteen units were built in Canada, including the last two in August, 1963. Power was provided by an EMD 567C sixteen-cylinder engine which generated 1,750 horsepower (1.30 MW). This locomotive type was offered both with and without control cabs; locomotives built without control cabs were called GP9B locomotives. All GP9B locomotives were built in the United States between February, 1954, and December, 1959.
One option available for locomotives without dynamic brakes, was to remove the two 22.5 in × 102 in (571.5 mm × 2,590.8 mm) air reservoir tanks from under the frame, and replace them with four 12 in × 150.25 in (304.80 mm × 3,816.35 mm) tanks that were installed on the roof of the locomotive, above the prime mover. These “torpedo tubes” as they were nicknamed, enabled the fuel and water tanks to be increased to 1,100 US gallons (4,200 l; 920 imp gal) each, although some railroads opted for roof-mounted air tanks and 2,200 US gallons (8,300 l; 1,800 imp gal) fuel tanks on their freight ‘Geeps’.

Road Name History: 
The DT&I was born in 1905 with the sale and reorganization of the Detroit Southern Railroad. Beginning in Detroit, the DT&I carved a huge northwest to southeast arc around western Ohio, serving Lima (like the bean, not Peru), Springfield, Jackson, and finally the Ohio River port of Ironton on the Kentucky border. Toledo was reached via a short segment of trackage rights on the Ann Arbor.
In 1920, as part of a complicated solution to realigning a shipping channel that served Henry Ford’s River Rouge plant, Ford bought the DT&I. The Ford years brought a ban on facial hair, uniform white hats and an expectation that crews keep their overalls clean and tidy. He also strung catenary and bought heavy electric locomotives for a 17 mile line segment between his River Rouge plant and Carolton, Michigan. During this period, the DT&I closed for business on Sundays. In 1929, Ford sold the line to Pennroad Corporation, a holding company affiliated with the Pennsylvania Railroad.
The steam fleet of the DT&I was a pretty homely lot. 2-8-0s and Russian Decapods were the kings of the road for the first few decades. As the tide of traffic turned from coal and minerals from the south end of the line to automobiles from the north end of the line, DT&I went to Lima Locomotive Works for faster stronger 2-8-4 Berkshires. Although the DT&I Berks were light and stumpy by Berkshire standards, they were a bit too much for DT&I’s physical plant so their final steam orders were for very heavy Mikados ( 20 tons heavier than USRA Heavy Mikes.) By 1955, they had completely dieselized with 37 EMD GP7’s and GP9’s setup for short hood forward operation (interesting given their ties to the Pennsylvania Railroad who preferred long hood forward operation) and 24 various EMD switchers.
The DT&I diesel fleet has always been solid orange but the logo on the long hood was smaller and more reserved in the 1950s. Second generation diesels included 8 GP35’s, 21 GP38’s, 6 GP40’s, 5 SD38’s (used in hump service,) 8 GP38-2’s, and 20 GP40-2’s. Features included a general lack of dynamic brakes and nose mounted gong style bells (a feature familiar to fans of Chicago & North Western.)
The freight car fleet was very, very colorful. Often, special colors were used to identify groups of cars for large customers. Ocean blue boxcars were for General Mills, Army green went to a paper mill on the Soo Line, yellow went to Campbell Soup, and of course, the auto parts cars which came in sky blue, cypress green, and magenta.
In 1963, and with control having been passed from Pennroad to The Pennsylvania Company (another holding company at arms length from the PRR,) the DT&I gained control of the Ann Arbor from their parent Wabash, turning the AA orange. This was part of the complicated arrangements made in the run up to the Penn Central merger. PRR needed to end their control of Wabash but wanted to hold onto DT&I and Ann Arbor. DT&I control ended in 1973 when AA declared bankruptcy.
In 1976, the DT&I was profitable even though parent Penn Central was in bankruptcy. Therefore DT&I was not included in the Conrail consolidation. In fact Conrail gave DT&I trackage rights on their lines from Springfield to Cincinnati, which gave DT&I even more Ohio River access as well as friendly connections with Southern and Louisville & Nashville. Meanwhile, The Pennsylvania Company, stripped of its Penn Central parent, put the DT&I up for sale. Grand Trunk Western offered to buy it and Chessie and N&W offered to jointly buy it. The ICC went with Grand Trunk Western and the sale was completed in 1980. Some locomotives were painted in GTW blue and red but with DT&I logos. In 1983, the DT&I officially merged into GTW.

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.
