Model Information: InterMountain introduced this model in 2005, and have since followed up with several subsequent runs. The model shares the same chassis as Intermountain's F7s. The PC board was re-designed in 2014 with motor contact "shoes" replaced by wires.

In December 2014, a new run of several road numbers was announced which introduced new factory DCC-equipped versions, sound and non-sound. These models come with a brand new design that incurred significant delays. First batch is expected to be delivered mid-2017.

These locos sport all of the niceties one normally associates with "modern" diesel models, e.g. - split-frame DCC-Ready metal chassis, dual-flywheels, low-friction drive, plastic truck assemblies, plastic gearing, blackened wheels, all-wheel drive / pick-up (no traction tires). The motor is an open-sided 5-poler. Directional lighting on A units is controlled by a PC board mounted on top of the chassis, and with the LED headlight mounted on the front of the chassis (with wires running between the two).
DCC Information:
Models released up to 2014: These locos are qualified as "DCC-Friendly" and not "Ready" because installing after-market decoders requires de-soldering and re-soldering a few wires. Not too complex, but you'll need a soldering iron...
- For locos released before 2014: front light of A units needs to be re-soldered to the decoder board.
- For locos released after 2014: in addition to the front light, the motor contacts are performed by two wires that need to be re-soldered to the decoder board.

Accepts the following decoders (non-sound):
- Digitrax DN163I1C: 1.5 Amp N Scale Mobile Decoder for Intermountain F3 / F7 Units. (discontinued)
- Digitrax DN166I1C: 1.5 Amp Decoder for Intermountain N scale F3 and F7 A & B units with motor contact "shoes".
- Digitrax DN166I1D: 1.5 Amp Decoder for InterMountain N Scale F7A & B units with wired motors produced after Jan 2014.
- TCS IMF4: 4 Function Decoder for Intermountain F3A/B, F7A/B and F9B N-Scale locomotives. (Installation for Intermountain F3A)
- TCS IMF4-NF: 4 Function Decoder for Intermountain F3A/B, F7A/B and F9B N-Scale locomotives produced after Jan 2014. (Installation for Intermountain F7A)

Models released as of 2017: this model is proposed factory-equipped with either a non-sound DCC decoder (models suffixed by "D") or a sound DCC decoder (models suffixed by "S"), both from ESU - LokSound Select Micro or LokPilot Micro.
Prototype History:
The EMD F3 was a 1,500-horsepower (1,100 kW) B-B freight- and passenger-hauling diesel locomotive produced between July 1945 and February 1949 by General Motors’ Electro-Motive Division. Final assembly was at GM-EMD's La Grange, Illinois plant. A total of 1,111 cab-equipped lead A units and 696 cabless booster B units were built.

The F3 was the third model in GM-EMD's highly successful F-unit series of cab unit diesel locomotives, and it was the second most produced of the series. The F3 essentially differed from the EMD F2 in that it used the “new” D12 generator to produce more power, and from the later EMD F7 in electrical equipment. Some late-model F3's had the same D27 traction motors, along with the heavier-duty electrical cables, used in the F7, and were referred to as model F5 by EMD's Engineering Department.

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:
InterMountain was founded in 1985 by Fred Brummet. They got started in the model railroad business by producing O-Scale model kits. They got started in the N Scale business almost a decade later when in 1994 they introduced the 40-23 reefer car in kit form. Later, in 1998, they started producing RTR (Ready-to-Run) models. By the early 2000s, InterMountain phased out kit production in favor of the RTR models.

The InterMountain Railway company is located at 1224 Boston Ave in Longmont, CO. They are a manufacturer of HO, N and Z scale model trains. They have produced kits as well as RTR (Ready-To-Run) models. Their N Scale products include locomotives as well as rolling stock. Their rolling stock lineup includes Boxcars, Hoppers, Tank Cars, Reefers, Gondolas, Stock Cars and Flatcars.

Their locomotive releases have primarily been diesel units, with the one major exception being their series of AC-12 Cab Forward steam locos. Their diesel lineup includes F3's, F7's, F9's, SD40's, SD45's and FT units. They are known for quality and detail. They also release their rolling stock in larger varieties of road numbers than most of the other manufacturers.
