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 New York, New Haven and Hartford Railroad (reporting mark NH), commonly known as the New Haven, was a railroad that operated in New England from 1872 to 1968, dominating the region's rail traffic for the first half of the 20th century.

Beginning in the 1890s and accelerating in 1903, New York banker J. P. Morgan sought to monopolize New England transportation by arranging the NH's acquisition of 50 companies, including other railroads and steamship lines, and building a network of electrified trolley lines that provided interurban transportation for all of southern New England. By 1912, the New Haven operated more than 2,000 miles (3,200 km) of track, with 120,000 employees, and practically monopolized traffic in a wide swath from Boston to New York City.

This quest for monopoly angered Progressive Era reformers, alienated public opinion, resulted in high prices for acquisitions, and increased construction costs. Debt soared from $14 million in 1903 to $242 million in 1913, even as the advent of automobiles, trucks and buses reduced railroad profits. Also in 1913, the federal government filed an anti-trust lawsuit that forced the NH to divest its trolley systems.

The line became bankrupt in 1935, was reorganized and reduced in scope, went bankrupt again in 1961, and in 1969 was merged with the Penn Central system, formed a year earlier by the merger of the also bankrupt New York Central Railroad and Pennsylvania Railroad; Already a poorly conceived merger, Penn Central proceeded to go bankrupt in 1970, becoming the largest bankruptcy in the U.S. until the Enron Corporation superseded it in 2001. The remnants of the system now comprise Metro-North Railroad's New Haven Line, (parts of) Amtrak's Northeast Corridor, Shore Line East, parts of the MBTA, and numerous freight operators such as CSX and the Providence and Worcester Railroad. The majority of the system is now owned publicly by the states of Connecticut, Rhode Island, and Massachusetts.

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.
