Specific Item Information: Unmotorized Dummy Unit. Initial release with the European-style trucks.

Model Information: This model was introduced in 1968. It has gone through some modifications over the years. The initial release used the same mechanism as one of Lima's earlier European prototype locomotives. It uses a Lima pancake motor and does run very well. Pickup is only from the front truck and traction only from the rear truck. The rear truck also uses traction tires. The lighting is non-directional.
The model was available in Motorized or Dummy versions.
It was used as the locomotive in various sets from AHM. Lima also imported them under their own name/packaging.

DCC Information: Pre-DCC era, not supported.

Prototype History:
The F7 was the fourth model in GM-EMD's successful line of F unit locomotives, and by far the best-selling cab unit of all time. In fact, more F7's were built than all other F units combined. It succeeded the F3 model in GM-EMD's F unit sequence, and was replaced in turn by the F9. Final assembly was at GM-EMD's La Grange, Illinois, plant or GMD's London, Ontario, facility.

The F7 differed from the F3 primarily in internal equipment (mostly electrical) and some external features. Its continuous tractive effort rating was 20% higher (e.g. 40,000 lb (18,000 kg) for an F7 with 65 mph (105 km/h) gearing, compared to 32,500 lb (14,700 kg) for an F3 with the same gearing.

A total of 2,366 cab-equipped lead A units and 1,483 cabless-booster or B units were built. (Note: the B unit is often referred to as an "F7B", whereas the A unit is simply an "F7".)

Many F7s remained in service for decades, as railroads found them economical to operate and maintain. However, the locomotive was not very popular with yard crews who operated them in switching service because they were difficult to mount and dismount, and it was also nearly impossible for the engineer to see hand signals from a ground crew without leaning way outside the window. As most of these engines were bought and operated before two-way radio became standard on most American railroads, this was a major point of contention. In later years, with the advent of the "road switchers" such as the EMD GP7, F units were primarily used in "through freight" and "unit train" service where there was very little or no switching to be done on line of road.

Road Name History:
The Atchison, Topeka and Santa Fe Railway (reporting mark ATSF), often abbreviated as Santa Fe or AT&SF, was one of the larger railroads in the United States. Chartered in February 1859, the railroad reached the Kansas-Colorado border in 1873 and Pueblo, Colorado, in 1876. To create a demand for its services, the railroad set up real estate offices and sold farm land from the land grants that it was awarded by Congress. Despite the name, its main line never served Santa Fe, New Mexico, as the terrain was too difficult; the town ultimately was reached by a branch line from Lamy.

The Santa Fe was a pioneer in intermodal freight transport, an enterprise that (at one time or another) included a tugboat fleet and an airline (the short-lived Santa Fe Skyway). Its bus line extended passenger transportation to areas not accessible by rail, and ferryboats on the San Francisco Bay allowed travelers to complete their westward journeys to the Pacific Ocean. The ATSF was the subject of a popular song, Harry Warren & Johnny Mercer's "On the Atchison, Topeka and the Santa Fe", written for the film, The Harvey Girls (1946).

The railroad officially ceased operations on December 31, 1996, when it merged with the Burlington Northern Railroad to form the Burlington Northern & Santa Fe Railway.

Paint Scheme:
While there were many, now-classic paint schemes to grace locomotives during the start of the diesel and streamliner age of the 1930s none became as legendary as Santa Fe's "Warbonnet" (and most did not even receive a formal name). The design was the creation of artist Leland A. Knickerbocker, who worked for General Motors. During the mid-1930s the company needed a classy, matching livery to the Native-American themed train that the Santa Fe was planning to debut. Of course, you probably know the name of this train, the Super Chief, which went on to become just as famous as the paint it wore.

The Warbonnet was shelved by the railroad following the end of passenger service in 1971 but was readopted in the late 1980s. Following the creation of Burlington Northern Santa Fe in 1995 a version of the livery was briefly used but was finally dropped altogether.

Brand/Importer Information:
AHM is the initials for Associated Hobby Manufacturers, Inc. The company was founded in 1959 as a reseller of other companies' model railroad components. Initially an HO company, they entered into N Scale in the early 1970's as an importer of products made by Roco in Austria. For N Scale products, AHM apparently contracted to use the exact same molds as were used by Roco to produce early Atlas models. They also contracted with Rivarossi to make locomotives.

When AHM went out of business IHC picked up some of their line. Also, at least one body style was taken over by Eastern Seaboard models.


Manufacturer Information:
Lima S.p.A (Lima Models) was a brand of railway models made in Vicenza, Italy, for almost 50 years, from the early 1950s until the company ceased trading in 2004. Lima was a popular, affordable brand of 00 gauge and N gauge model railway material in the UK, more detailed H0 and N gauge models in France, Germany, Italy, Switzerland, and the United States as well as South Africa, Scandinavia and Australia. Lima also produced a small range of 0 gauge models. Lima partnered with various distributors and manufacturers, selling under brands such as A.H.M., Model Power, Minitrain and PMI (Precision Models of Italy). Market pressures from superior Far Eastern produce in the mid-1990s led to Lima merging with Rivarossi, Arnold, and Jouef. Ultimately, these consolidations failed and operations ceased in 2004.

Hornby Railways offered €8 million to acquire Lima's assets (including tooling, inventory, and the various brand names) in March of the same year, the Italian bankruptcy court of Brescia (town near Milan, last headquarters of Lima) approving the offer later that year. In December 2004, Hornby Railways formally announced the acquisition along with the Rivarossi (H0 North American and Italian prototypes), Arnold (N scale European prototypes), Jouef (H0 scale French prototypes), and Pocher (die-cast metal automobile kits) ranges. As of mid-2006, a range of these products has been made available under the Hornby International brand, refitted with NEM couplings and sprung buffers and sockets for DCC (Digital Command Control) decoders.
