Mainline freight service was the last stronghold for steam power in America. By the late 1930s, diesels had proven themselves as switchers and as power for the new streamlined trains, but there were doubts that they could ever be practical in freight service.
That all changed in late 1939 when EMD rolled out its brand-new FT locomotive. Borrowing some basic design elements from E series passenger power, but in a shorter, more powerful package, the demonstrator set out on a 35-state tour that covered nearly 90,000 miles. Railroads were amazed at what this single A-B-B-A lash-up with its incredible 5400 horsepower could do, and orders came quickly. With its proven track record, EMD was the only builder allowed to construct road diesel power during the materials shortages of World War II.
Starting in 1945, the basic design underwent a number of changes, resulting in the F2, F3 and F5. But with the arrival of the F7 in 1949, EMD had exactly what the railroads needed to begin dieselizing with a vengeance. The F7 retained the 1500 horsepower 567B prime mover of the F3, but with better electrical equipment, it had a tonnage rating some 30% greater than the earlier model. The units could be geared for freight or passenger service, and were equally at home in either assignment. Over the next four years EMD built over 2200 A and 1400 B units, which were delivered in a rainbow of schemes to nearly every railroad in America. Tough and durable, many soldiered on into the early 70s and several have been preserved.
* Factory-Installed Sound & DCC Sound can be operated with standard DC power pack as well as DCC controllers. Sound features include: Diesel Engine, Horn, Bell, Squealing Brakes, Doppler Effect, Air Let Off (in neutral), Headlight, and Trailer which mutes whistle and bell for double heading.
HISTORY:
The EMD F7 is a model of 1,500-horsepower (1,100 kW) diesel-electric locomotive produced between February 1949 and December 1953 by the Electro-Motive Division of General Motors (EMD) and General Motors Diesel (GMD).
Although originally promoted by EMD as a freight-hauling unit, the F7 was also used in passenger service hauling trains such as the Santa Fe Railway's high-speed flagship trains, the Super Chief, & El Capitan, and the Ontario Northland's Northlander.
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 F7s were built than all other F-units combined. The F7 succeeded the F3 model in GM-EMD's F-unit series, 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. There was no F4, -5 or -6 model; "7" was chosen to match the contemporary twin-engine E7, and was also applied to the new GP7 road-switcher.
The F7 differed from the F3 primarily in internal equipment—mostly electrical—and some external features. Its continuous tractive effort rating was 20 percent higher, e.g. 40,000 lbf (180 kN) for an F7 with 65 mph (105 km/h) gearing, compared to 32,500 lbf (145 kN) for an F3 with the same gearing.
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 little or no switching to be done.
Engine and powertrain
The F7's prime mover is a 16-cylinder 567B series diesel engine developing 1,500 hp (1.1 MW) at 800 rpm. The 567B is a mechanically aspirated two-stroke design in a 45-degree V engine configuration, with 567 cu in (9.29 L) displacement per cylinder, for a total of 9,072 cu in (148.66 L). A direct current generator that is mechanically coupled to the flywheel end of the engine powers four traction motors, with two motors mounted on each Blomberg B truck. EMD has built all of its major components since 1939.
Identification
There are no easily identifiable differences between late F3 production and early F7 production; the major differences were all internal electrical system changes. However, no F7 had the "chicken wire" grilles seen on most F3s, and no F3s had later F7 changes described below under Phases.
The F9 is distinguishable from the late F7 by having five, rather than four, carbody center louver groups covering the carbody filters. The additional one is placed ahead of the first porthole, where F7s have no openings. The F9's greater power output, of course, cannot be seen from the outside.
There were also two main classes of F7s: passenger and freight. Most passenger units had upper and lower headlights, but there were exceptions. Many freight units had the upper Mars or Pyle brand warning light as well. And some passenger units only had a single upper headlight, i.e. the Pennsylvania. Many units eventually had the upper lights or the door light removed/plated over and the Mars/Pyle light removed. These early warning lights had a motor and linkages that often required maintenance in the shops.
Rebuilds
MARC Train #83, a former B&O F7 rebuilt into an F9PH, at Brunswick, Maryland in 1994.
Several F7s were rebuilt by Morrison–Knudsen as F9PHs and used in passenger operations. Others were rebuilt as the "FP10" and used by the Massachusetts Bay Transportation Authority for their commuter rail service. In addition, the Santa Fe had 190 of their F7As rebuilt into CF7 hood units in the 1970s. Only one original F7 unit from the railway exists to this day.
In the early 2000s, a single unpowered EMD F cab unit #7100 (ex-Baltimore & Ohio Railroad F7 #4553) operated on MARC, occasionally substituting for a cab car. In addition to serving as an all-purpose control unit, it also had a head-end power generator that supplied electricity to the train.
