Prototype History: The EMD FP7 was a 1,500 horsepower (1,100 kW), B-B dual-service passenger and freight-hauling diesel locomotive produced between June 1949 and December 1953 by General Motors' Electro-Motive Division and General Motors Diesel. Final assembly was at GM-EMD's La Grange, Illinois plant, excepting locomotives destined for Canada, in which case final assembly was at GMD's plant in London, Ontario. The FP7 was essentially EMD's F7A locomotive extended by four feet to give greater water capacity for the steam generator for heating passenger trains.

While EMD's E-units were successful passenger engines, their A1A-A1A wheel arrangement made them less useful in mountainous terrain. Several railroads had tried EMD's F3 in passenger service, but there was insufficient water capacity in an A-unit fitted with dynamic brakes. The Atchison, Topeka and Santa Fe Railway's solution was to replace the steam generators in A-units with a water tank, and so only fitted steam generators into the B-units. The Northern Pacific Railway's solution was to fit extra water tanks into the first baggage car, and to pipe the water to the engines. The real breakthrough came when EMD recognized the problem and added the stretched FP7 to its catalog.

A total of 381 cab-equipped lead A units were built; unlike the freight series, no cables booster B units were sold. Regular F7B units were sometimes used with FP7 A units, since they, lacking cabs, had more room for water and steam generators. The FP7 and its successor, the FP9, were offshoots of GM-EMD's highly successful F-unit series of cab unit freight diesels.

F3s, F7s, and F9s equipped for passenger service are not FP-series locomotives, which although similar in appearance have distinctive differences, including but not limited to the greater body length. The extra 4 ft (1.2 m) of length was added behind the first body-side porthole, and can be recognised by the greater distance between that porthole and the first small carbody filter grille. The corresponding space beneath the body, behind the front truck, was also opened up; this either remained an empty space or was filled with a distinctive water tank shaped like a barrel mounted transversely.

Railroads found that Fs, with their better tractive effort performed much better than Es in passenger service on routes with stiff grades. However, as a freight model lacking steam generators it was not a possible unless a separate heating car was used or Es were in the consist. EMD corrected the issue with its FP7, released in the late 1940s, built at the same time as the F7. Surprisingly, for a variant model the locomotive sold quite well with nearly 400 examples manufactured (including those constructed by General Motors Diesel of London, Ontario). Today, numerous FP7s remain preserved and in operation around the country.

Road Name History: Born in 1923 with the consolidation and connection of the Tanana Valley and Alaska Northern railroads, the line was owned by the Federal Government (under the Department of the Interior) from the outset, later becoming the responsibility of the Department of Transportation in 1967. In the mid-80s it was sold to the State of Alaska.

The Alaska Railroad links Anchorage with the port of Whittier and Seward to the south, and Fairbanks and environs to the north. Total mileage is about 525 putting it between Bangor & Aroostook and New York Ontario & Western in relative size. Alaska does run its own passenger service over the length of the railroad. Although the Alaska Railroad is disconnected from the rest of the North American rail network, they do interchange with other railroads. A trio of sea-going barges ferry rail cars from the port of Whittier to Prince Rupert, British Columbia, and Seattle, Washington. ARR had collected a fleet of Alco RS-1s (and a few RSD-1’s) with cowls, effectively making them cab units unique to this line. These were later replaced by second generation EMD power. The big power on the line is a fleet of 28 SD70MACs. A dozen of these are equipped with HEP for use in passenger service.

The port of Whittier is hemmed in by the ocean on one side and mountains on the other. A 2.5 mile single track tunnel is the only way out of the port. The line through the tunnel is paved like street trackage so that highway traffic can use the tunnel. It is a single lane so highway traffic going south enters from the top of the hour until quarter after. Northbound traffic enters from the bottom of the hour until 45 after the hour. Trains get priority and proceed as soon as traffic has cleared.

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.
