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:
The original Western Pacific Railroad was established in 1865 to build the westernmost portion of the Transcontinental Railroad between San Jose, California (later Oakland, California), and Sacramento, California. This company was absorbed into the Central Pacific Railroad in 1870.
The second company to use the name Western Pacific Railroad was founded in 1903. Under the direction of George Jay Gould I, the Western Pacific was founded to provide a standard gauge track connection to the Pacific Coast for his aspiring Gould transcontinental system. The construction was financed by the Denver and Rio Grande Western Railroad, a company in the Gould system, which lost access to California due to the attempted acquisition of the Southern Pacific Railroad by the Rio Grande's main rival, the Union Pacific Railroad. The Western Pacific Railroad acquired the Alameda and San Joaquin Railroad and began construction on what would become the Feather River Route. In 1909 it became the last major railroad completed into California. It used 85-lb rail on untreated ties, with no tie plates except on curves over one degree; in 1935 more than half of the main line still had its original rail, most of it having carried 150 million gross tons.
The Western Pacific was acquired in 1983 by Union Pacific Corporation, which in 1996 would purchase its long-time rival, the Southern Pacific Railroad. In July 2005 Union Pacific unveiled a brand new EMD SD70ACe locomotive, Union Pacific 1983, painted as an homage to the Western Pacific.
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.
