Model Information: This model was first produced by Kato for Atlas in 1989. The model was retooled and production transferred to China in 1998. In 2003, the mechanism was updated again and a slow speed motor was introduced.

Although the retooling was performed in 1998, this model has all the features one would expect of a 2000's vintage design. A split-frame, flywheels, blackened wheels and body-mounted couplers. It runs quite well and can pull plenty of cars.

DCC Information: The early Kato models are all kinda-sorta DCC friendly, but IMHO, I wouldn't bother. Buy a new mechanism and drop your old shell on it. It will likely fit (no promises though!). All the 1998+ accept DCC boards and many come with factory-installed decoders. For the DCC-Ready versions, they accept the DN163A0 decoder: 1 Amp N Scale Mobile Decoder for Atlas N-Scale GP40-2, U25B, SD35, Trainmaster, B23-7 and others from digitrax.com.

Prototype History:
The GE U25B was General Electric's first independent entry into the United States domestic Diesel-electric locomotive railroad market for heavy production road locomotives since 1936. From 1940 through 1953, GE participated in a design, production, and marketing consortium (Alco-GE) for diesel-electric locomotives with the American Locomotive Company. Starting in 1956 GE launched its Universal Series of diesel locomotives for the export market. The U25B was the first attempt at the domestic market since its termination of the consortium agreement with Alco.

The U25B (nicknamed U-Boat) was the first commercially successful domestic diesel electric road locomotive designed, built, and sold by General Electric after its split with the American Locomotive Company (Alco), a company dating back to the steam era. Along with Ingersoll-Rand, GE built the first viable American diesel-electric locomotive in 1928. In 1940 GE partnered with ALCO to enter regular production of Diesel locomotives. They were successful in building locomotives for switching and short-haul applications, having introduced the first road-switcher design in 1941 (which would supplant the carbody design developed by the Electro-Motive Corporation by the mid-1950s) and gained about a 40% market share during the Dieselization era. ALCO-GE's efforts in main line road locomotives had not been successful at breaking into EMD's dominant position in that market, although they introduced a successful gas turbine-electric locomotive to market in 1952. In 1953 GE went independent from ALCO in locomotive production, with their new subsidiary GE Rail taking over the gas turbine-electric venture while they sought a supplier of more reliable Diesel engines suitable for road locomotives. Production of Cooper-Bessemer powered Universal Series locomotives began in 1956 and some 400 export locomotives were sold before the U25B was offered in the United States. The U25B was announced by General Electric as a domestic model on April 26, 1960. It was the first locomotive powered by GE's highly successful FDL-16 engine.

Road Name History:
The Great Northern was born in 1881 with the consolidation of several railroads of the northern plains under the leadership of James J. Hill. By 1893, the mainline from the Great Lakes and the Mississippi River to Seattle was complete.

The GN had two distinctly different characters. The eastern half was a largely flat, grain producing region serving cities like Fargo, the Twin Cities, Grand Forks, Duluth, Sioux Falls, Sioux City and even Winnipeg in Canada. The east end also included the iron ore rich regions of Minnesota. Half of North Dakota was blanketed by GN branchlines (21 in all) serving every imaginable grain elevator.

The western half is the mountainous portion that most people identify with Great Northern. This included crossing the northern Rockies and the even more difficult Cascade ranges. Cities on the western half included Billings, Butte, Helena, Havre, Spokane, Portland, Seattle, and Vancouver. In 1931, a connection to the Western Pacific was completed from Bieber north to Bend, Oregon. This line was disconnected from the rest of the Great Northern. They used trackage rights on the Oregon Trunk and SP&S to bridge the gap. The Cascade Tunnel, the longest on the continent at 7.8 miles, wasn’t completed until 1931. Construction included a massive sluiceway and hydro-electric power station to feed the electrified line through the tunnel and several miles of railroad on either side. This replaced the original Cascade Tunnel which was a third as long but 500 feet higher up the mountain. That replaced the original route that was another 700 feet higher, had 4% grades and 50 miles of snowsheds. All told, Great Northern had about 8,300 route miles.

The steam era was especially unkind to the Great Northern. They seemed to go out of their way to make their locomotives ugly. Belpaire fire boxes were the norm (made famous by the Pennsylvania, made hideous on the GN.) Headlights were often mounted just above center giving them a spinster look. Cab fronts were often at odd angles. The tender coal bunkers were often taller than the engines. But it wasn’t just aesthetics. GN had a knack for buying the wrong engines for the job. 150 Prarie type 2-6-2’s were so unstable at speed that they were busted down to branchline duty almost straight away and none survived after about 1930. Their first 4-8-2 Mountains built for passenger and fast freight were such a disaster, they were rebuilt into 2-10-2’s. Many railroads had built Mountains out of Mikes but no one had ever started with a Mountain and had to build something else from it. The first 2-6-6-2’s were so under-powered, the boilers were used to make Mikados instead. They did manage to build the largest, fastest, and most powerful Mikados in the country however. Their articulated fleet included 2-6-6-2, 2-6-8-0 (later rebuilt into Mikes), 2-8-8-0, 2-8-8-2 types as well as a pair of Challengers originally delivered to SP&S. Many engines were dressed up with green boilers and boxcar red cab roofs.

For the first generation of diesels, GN bought like many large railroads did: a sampling from everyone. Cab and hood units from EMD and Alco and switchers from EMD, Alco, and Baldwin populated the roster. GN’s first generation geeps and SD’s were delivered with the long hood as the front. This included their GP20’s which had high short hoods and the long hood as the front. Aside from an early black scheme for switchers, the GN fleet was delivered in Omaha Orange and green with yellow piping.

Beginning with the arrival of GP30s in 1962, the paint scheme was simplified by dropping the bottom orange band and the yellow piping. For the second generation, General Electric replaced Alco as a supplier of new road engines.

In 1962, some GN freight cars began to appear in Glacier Green which ran along side the vermilion paint adopted in 1956. In 1967, they went for a major shift. Sky Blue, white, and dark gray were joined by a new version of the Rocky the goat logo. There was talk that this would become the paint scheme for Burlington Northern. The GN name and logo was painted on a steel panel bolted the the hand railings of hood units, making it easier to remove after the merger. For whatever reason, they went with green, black and white, a version of which was simultaneously being tested on the Burlington Route. In 1970, Great Northern, Northern Pacific, Spokane Portland & Seattle, and Burlington Route merged to form Burlington Northern.

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.
