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 Andover and Wilmington Railroad was incorporated March 15, 1833, to build a branch from the Boston and Lowell Railroad at Wilmington, Massachusetts, north to Andover, Massachusetts. The line opened to Andover on August 8, 1836. The name was changed to the Andover and Haverhill Railroad on April 18, 1837, reflecting plans to build further to Haverhill, Massachusetts (opened later that year), and yet further to Portland, Maine, with the renaming to the Boston and Portland Railroad on April 3, 1839, opening to the New Hampshire state line in 1840.
The Boston and Maine Railroad was chartered in New Hampshire on June 27, 1835, and the Maine, New Hampshire and Massachusetts Railroad was incorporated March 12, 1839, in Maine, both companies continuing the proposed line to South Berwick, Maine. The railroad opened in 1840 to Exeter, New Hampshire, and on January 1, 1842, the two companies merged with the Boston and Portland to form a new Boston and Maine Railroad.
The B&M flourished with the growth of New England's mill towns in the late 19th and early 20th centuries, but still faced financial struggles. It came under the control of J. P. Morgan and his New York, New Haven and Hartford Railroad around 1910, but anti-trust forces wrested control back. Later it faced heavy debt problems from track construction and from the cost of acquiring the Fitchburg Railroad, causing a reorganization in 1919.
By 1980, though still a sick company, the B&M started turning around thanks to aggressive marketing and its purchase of a cluster of branch lines in Connecticut. The addition of coal traffic and piggyback service also helped. In 1983 the B&M emerged from bankruptcy when it was purchased by Timothy Mellon's Guilford Transportation Industries for $24 million. This was the beginning of the end of the Boston & Maine corporate image, and the start of major changes, such as the labor issues which caused the strikes of 1986 and 1987, and drastic cost cutting such as the 1990 closure of B&M's Mechanicville, New York, site, the largest rail yard and shop facilities on the B&M system.
Guilford Rail System changed its name to Pan Am Railways in 2006. Technically, Boston & Maine Corporation still exists today but only as a non-operating ward of PAR. Boston & Maine owns the property (and also employs its own railroad police), while Springfield Terminal Railway, a B&M subsidiary, operates the trains and performs maintenance. This complicated operation is mainly due to more favorable labor agreements under Springfield Terminal's rules.

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.
