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.
- 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:
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:
This line was established in 1852 under another name but was renamed Western Maryland Rail Road before the first rail was laid. By 1862 they had built from Baltimore to Union Bridge, Maryland at which point it became the responsibility of the Union Army. Construction resumed after the war. WM built west to Hagerstown then Cumberland where the line spilt in two. One route headed northwest to an important interchange with Pittsburgh & Lake Erie at Connellsville, Pennsylvania. The other line ran southwest into the rich coal fields around Elkins and Durban, West Virginia. On the east end, they also had routes to York and Gettysburg and an important connection with the Reading at Shippensburg, all in Pennsylvania. At 878 miles, WM was between Maine Central and Spokane Portland & Seattle in relative length.

The city of Baltimore had a large stake in the WM but sold it in 1902 to Jay Gould. The Gould empire unraveled just six years later and the WM was reorganized with Railway replacing Rail Road in the name and John D. Rockefeller holding a 43% stake. He sold those shares to Baltimore & Ohio in 1927. Accused of violating antitrust laws, B&O placed those shares in a non-voting trust.

After 1900, WM relied heavily on 2-8-0’s, ordering 177 between 1900 and 1923 (by which time other railroads were already ordering 2-8-2’s.) Some of these Consolidations were real bruisers with the same tractive effort as WM’s 2-6-6-2’s. Also in road service were 30 2-10-0 Decapods (10 Russian Decapods and 20 much larger versions,) a dozen 4-8-4’s to handle the high speed trains, and a dozen 4-6-6-4 Challengers. The Challengers turned out to be a disappointment to WM. They were rough riders and were hard on the track. As a result, they were soon demoted to pusher service alongside WM’s 25 2-8-8-2’s. A fleet of 19 low drivered Pacifics handled most of the passenger assignments. One element found on most of the WM steam fleet was low snowplow pilots in lieu of the traditional boiler tube pilots. WM was one of a few Class One railroads to employ Shay locomotives to serve steeply graded branchlines. WM had one 2-truck, two 3-truck and two 4-truck Shays. Shay #6 built in 1945 was the last Shay built by Lima Locomotive Works.

WM began to dieselize in 1947 on the east end where they would not raise the ire of their coal mining customers on the west end. The diesel fleet was surprisingly varied for a line their size with cab units from both Alco and EMD, road switchers from Alco, EMD and Baldwin and yard switchers from GE, Baldwin and Alco. The road switchers from Alco and Baldwin plus the EMD GP7;s were delivered with the long hood as the front while the EMD GP9’s were delivered with the short hood as the front. The Second Generation of diesels was all EMD.

In addition to the voluminous coal traffic, WM was a part of two bridge routes for merchandise moving between the northeast and the upper Midwest. These were the Alphabet Route (with Nickel Plate Road, Wheeling & Lake Erie, Pittsburgh & West Virginia, Reading and others) and the Central States Dispatch (with Baltimore & Ohio, Reading, Jersey Central, Lehigh & Hudson River and New Haven.) Iron ore also moved from Baltimore area ports to steel mills on the connecting P&LE.

Passenger service was a bit of an afterthought on the WM. Not only did they not have a shiny streamliner, but their heavyweight coach trains lasted only until 1957 before being discontinued. Steam generator equipped hammerhead RS-3’s replaced the Pacifics in passenger service for a few years before being reassigned to freight duty.

In 1967, B&O (by this time controlled by Chesapeake & Ohio) finally obtained permission to take overt control of the WM. Not much changed for the next five years. In 1973 they adopted the Chessie System image and 125 miles of WM mainline was abandoned in favor of trackage rights on a parallel B&O line. In 1983, the Western Maryland was absorbed into the Baltimore & Ohio. Western Maryland was known for frequently washing their locomotives in both the steam and diesel eras. They kept up this tradition until the start of the Chessie System era.
Brand/Importer Information:
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.
