Model Information: The same mechanism is used for the GP38, GP38-2, GP40 and GP40-2. This model (GP40 only) 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 earliest (Mehano) releases only came as GP40'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.com.
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.
Standard GP40-2 production totalled 861 units, with 817 built for U.S. railroads, and 44 for Mexican railroads. In addition, three GP40P-2s, passenger versions of the GP40-2, were built for Southern Pacific in 1974, and 279 GP40-2L(W) and GP40-2(W) units, equipped with wide-nosed cabs, were built by General Motors Diesel (GMD), for Canadian National and GO Transit between 1974 and 1976. Of the CN units, 233 were built with a taller and lighter frame to allow for a larger fuel tank. These units were officially classified GP40-2L but are commonly referred to as GP40-2L(W). The balance of CN's fleet, 35 units, and the 11 unit GO Transit fleet, used standard frames and smaller fuel tanks; they are often referred to as GP40-2(W) but are classified as GP40-2. Total production of the GP40-2 and its variations totalled 1,143 units.
Although the GP40-2 was a sales success, it sold fewer units than the earlier GP40 and the contemporary GP38-2 and SD40-2 models. The popularity of high-horsepower 4-axle diesels began to decline with the GP40-2, with 6-axle models gaining in popularity for their superior low-speed lugging performance
Road Name History:
Union Pacific Railroad is the principal operating company of Union Pacific Corporation (NYSE: UNP); both are headquartered in Omaha, Nebraska. Over the years Union Pacific Corporation has grown by acquiring other railroads, notably the Missouri Pacific, Chicago & North Western, Western Pacific, Missouri-Kansas-Texas, and the Southern Pacific (including the Denver & Rio Grande Western).
Union Pacific Corporation's main competitor is the BNSF Railway, the nation's second largest freight railroad, which also primarily services the Continental U.S. west of the Mississippi River. Together, the two railroads have a duopoly on all transcontinental freight rail lines in the U.S.

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.
