Atlas - 53924 - Locomotive, Diesel, EMD GP40 - Dakota Minnesota & Eastern - 4003

Model Information: This model was first introduced by Atlas in 1969. This early version was made for Atlas by Mehano in Yugosolvia. It was later retooled and moved to Chinese production in 1996. It was later revised with a DCC-Ready chassis in 2003. The same mechanism is used for the GP38, GP38-2, GP40 and GP40-2.

The earliest (Mehano) releases only came as GP-40's. The other versions (GP38, GP38-2 and GP40-2) only arrived later after the production was moved to China.

Both of the Chinese mechanisms run fine but the first releases (1996) do not support drop in decoders. Both versions use a dual-flywheel, split frame chassis with a 5-Pole skew-wound motor.

The current model features:

• Golden-white LEDs;
• Separately-applied roof detail;
• Painted safety rails;
• Directional lighting;
• Blackened metal wheels;
• Scale Speed motor;
• Separately-applied coupler cut levers;
• Non-Dynamic, Dynamic, and Extended Range Dynamic Brakes used where appropriate;
• Pilot: Standard or with Snow Plow;
• Low short hood and High short hood versions available.

DCC Information: The Mehano versions do not support DCC at all. Early Chinese versions are DCC-friendly requiring a complicated split-board DCC install. Later versions are DCC-Ready accepting a 1 Amp N Scale Mobile Decoder for Atlas N-Scale GP40-2, U25B, SD35, Trainmaster, B23-7 and others (DN163A0) from Digitrax.

Unfortunately, the only way to tell which kind you have is to remove the shell and check the chassis. If it has two small lightboards, you have an old one in your hand. A single long lightboard indicates a DCC-Ready chassis.

Prototype History: The GP40 is a 4-axle diesel-electric road-switcher locomotive built by General Motors, Electro-Motive Division between November 1965 and December 1971. It has an EMD 645E3 16-cylinder engine generating 3,000 hp (2,240 kW).

The GP40 is 3 feet (0.914 m) longer than its EMD 567D3A-engined predecessor, the GP35, and distinguished visually by its three 48-inch radiator fans at the rear of the long hood, while the GP35 has two large fans and a smaller one in between. It was built on a 55 ft (16.76 m) frame; the GP35 was built on a 52 ft (15.85 m) frame - as was the GP7, 9, 18, and 30. The difference in length can be seen in the GP40's ten handrail stanchions compared to the GP35's nine.

1,187 GP40s were built for 28 U.S. railroads; 16 were built for one Canadian carrier, Canadian National; and 18 were built for two Mexican carriers, Ferrocarril Chihuahua al Pacifico and Ferrocarriles Nacional de Mexico. 60 units were built with high-short-hoods and dual control stands for Norfolk & Western Railway. Two passenger versions, the GP40P and GP40TC, were also built, but on longer frames to accommodate steam generators and HEP equipment.

On January 1, 1972, the GP40 was discontinued and replaced by the GP40-2, which has a modular electrical system and a few minor exterior changes.

Road Name History: The DM&E launched in 1986 as a spin-off of Chicago & North Western. The mainline ran from Winona, Minnesota (where there are Mississippi River docks) west to Rochester, Mankato, then onto Pierre and Rapid City, South Dakota. At that point the line split with one leg headed west to Colony, Wyoming, and the other leg headed south to Crawford, Nebraska. There were also a few other branchlines. Total mileage was 965 miles (putting it between Chicago & Eastern Illinois and Montana Rail Link in relative size.)

Operations began with 39 locomotives, mostly rebuilt SD9’s of Milwaukee Road heritage. Eventually DM&E dumped these first generation engines and in later years had a fleet of 69 rebuilt SD40-2’s, GP40-2’s, GP38-2’s, and a few one-offs. They also had about 5,000 freight cars, mostly grain hoppers.

In 1997, DM&E announced their intention to build a line to the huge coal reserves in Wyoming’s Powder River Basin. The project would have included rebuilding nearly the entire mainline plus building a new (and long) branch to reach the Basin. It would have been the biggest new construction since Great Northern’s Oregon Trunk in 1931. They did receive permission from the government but NIMBY opposition dragged out the start of construction for many years.

In 2008, The Dakota Minnesota & Eastern and sister road Iowa Chicago & Eastern were purchased by Canadian Pacific. After a bit of study, CPR wisely backed away from the Powder River Project.

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.
