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:
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.
