After dabbling in early diesel-electric boxcabs in 1935, and then introducing the first streamlined versions in 1937/1938 for the Baltimore & Ohio and Santa Fe (EA/E1), Electro-Motive forever changed railroading with the FT of 1939.
This four-unit set of streamlined cab locomotives made a quiet introduction to the industry in November, 1939 when Electro-Motive released the now-famous demonstrator set, #103, for testing without fanfare.
However, during the course of its 11-month, nationwide parade it wowed time and time again, proving diesels were more than capable of permanently retiring the steam locomotive in main line freight service.
The reason for EMC's success? Years of research in diesel locomotive development via motorcars, boxcabs, small switchers, and an early line of streamlined passenger diesels; a reliable power plant; studying historical applications of the most successful steam locomotives; months of fine tuning the #103 demonstrator set; and finally, excellent customer service.
In fact, Electro-Motive proved so successful that it not only retired the steam engine but would also eventually put the builders of these locomotives out of business.
Today, half of the original #103 demonstrator set is preserved; the lead "A" unit is on display at the Museum of Transportation in St. Louis while one of the "B" units is owned by the Virginia Museum of Transportation in Roanoke.
After witnessing the early streamliner's success in the mid-1930s, notable Union Pacific's M-10000 and Burlington's Pioneer Zephyr, Brian Solomon notes in his book, "The American Diesel Locomotive," Electro-Motive parent General Motors became convinced that the diesel locomotive could displace steam as standard power in main line service.
And there was great monetary potential in such a market as it was estimated the conversion from steam to diesel would cost the industry $4 billion. This belief led to the early boxcab's development and then the first "E" series streamlined models, designed by Electro-Motive's chief engineer Richard "Dick" Dilworth.
As Mike Schafer points out in, "Vintage Diesel Locomotives," Dilworth was also heavily involved in the FT project. Dilworth was a self-taught mechanical and electrical engineer who knew diesel engines very well, dating back to his days at General Electric when the company was involved in early diesel-electric switchers.
In developing the FT he was after a design not only capable of withstanding the everyday beating and pounding required in standard road service but also powerful enough to handle a heavy freight train.
Using General Motors' then-relatively new 12-cylinder model 567/567A prime mover, capable of producing 1,350 horsepower, Dilworth experimented with a locomotive concept that featured two engines on a single frame. Next, he equipped each locomotive with a pair of two-axle trucks powered with GM's model D7b traction motors.
The two units were semi-permanently coupled using a drawbar instead of a standard knuckle coupler, which officially gave the set a 2,700 horsepower rating. By adding another A-B pair, creating an A-B-B-A lashup, a four-unit set could produce an eye-popping 5,400 horsepower.
Such power rivaled nearly any steam locomotive of the era, albeit via four units instead of one. It was this A-B-B-A set that General Motors sent to market in 1939 as the FT. The new locomotive was given a beautiful streamlined carbody designed by the company's new styling department, then headed by legendary industrial designer Leland Knickerbocker.
- Knickerbocker created many of the colorful paint schemes from the early diesel era, including Santa Fe's classic "Warbonnet" livery. -
The FT was the first to sport the now-classic "bull dog" nose that was applied to all of EMD's future cab models. The decision to wrap the locomotive in a streamlined carbody was interesting, considering it was primarily intended to handle freight assignments (although could be optionally equipped for passenger service).
As Brian Solomon notes in his book, "Electro-Motive: E Units And F Units," the reasoning was multifaceted and included redundancy (as an outgrowth of the early streamlined "Es"), advertising GM's new product, and even safety as the frame was designed to fracture behind the cab in the event of a collision thus offering the crew a level of protection (the locomotive also featured front end plows and anti climbers).
Officially, the FT stood for Freight, Twenty-seven hundred horsepower (two units). The demonstrator set embarked on a cross-country tour in November, 1939 featuring A units #103 and #103A and B units #103(b) and #103A(b). Interestingly, while General Motors had heavily advertised its early "Es" and diesel switchers, the demonstrator set was released quietly from La Grange with little fanfare.
During the following eleven months the four-unit set operated on 20 Class I railroads, covering some 83,764 miles in 35 different states. In the process, it convinced the industry of diesels' superiority in main line service. Its efficiency, turnaround times, reliability, and speed was simply unmatched.
The "Railway Mechanical Engineer" from April, 1941, which was reprinted in the "Train Shed Cyclopedia: No. 58" from June, 1977, details this supremacy when the Santa Fe sent its A-B-B-A set #100 on a demonstration run from Argentine Yard in Kansas City to Los Angeles between February 8 - February 15, 1941.
In addition to freight cars, the train included a dynamometer car and five business cars so that AT&SF officers could see the railroad's first main line diesel-electrics in action. The "Railway Mechanical Engineer" articles notes the following:
"No particular attempt was made for a speed record either by means of unusually high operating speeds or reduced delays on the road and at terminals. As a matter of fact, the running time for this trip of 1,761.8 miles was 54 hr., 35½ min., which gives an average running speed of 32.3 mph.
The locomotive demonstrated ample reserve capacity to handle heavier trains than the one used in the test and at substantially higher speeds. For example, the test train, with a maximum of 68 cars and 3,150 tons, was handled successfully over ascending grades up to 1.6 per cent westbound, without a helper, and at a speed generally of about 30 mph. The maximum speed attained during the run was 68 mph between Amarillo, Tex., and Clovis, NM, this portion of the road being predominantly a 0.6 per cent ascending grade.
On descending grades, the locomotive gave an excellent account of itself due to the dynamic brake. This feature was used at four places during the run for a total of 83 miles; namely, from Mountainair, NM, to Belen, 17.5 miles; Supai, Ariz., to Ash Fork, 20.0 miles; Louise, Ariz., to Yucca, 23.0 miles; and Summit, Cal., to San Bernardino, 22.5 miles. Maximum grades on these four mountains ranged from 1.27 to 3 per cent. At a speed of 20 mph, the retarding effect exerted behind the locomotive was 48,000 lb., and the horsepower 2,560. At 29 mph, the corresponding figures were 35,200 lb., and the horsepower 2,730.
In negotiating the 3 per cent descending grade westward from Summit, the train length was limited to 50 cars in accordance with customary Santa Fe practice and the retaining valves were set up as an added safety measure.
Where the dynamic retarding brake was used, it was necessary to set the train air brake only about one-fourth as much as usual. There was no evidence of excessive wheel heating throughout the run and when stops were made after descending heavy grades, the wheels never much exceeded bare hand temperature.
The total energy absorbed by the dynamic brake during its use on this run is estimated at 19,700 million foot pounds, or approximately 10 per cent of the entire energy that was used to move the train throughout the test run.
The next most significant thing about this Diesel freight locomotive test run was the fact that a total of seven steam locomotives would ordinarily have been required to take the same train from Argentine to Los Angeles, with not less than 28 stops for water, on 12 of which fuel would also have been taken.
The Diesel locomotive made the entire trip with only four stops for fuel and the addition of a little engine cooling water; namely, at Wellington, Kan., Clovis, NM, Winslow, Ariz., and San Bernardino, Cal. The locomotive was serviced at Los Angeles and could have started the return trip, if necessary, with practically no delay."
Another reason for the FT's success was its application of dynamic braking, as noted in the previous "Railway Mechanical Engineer" excerpt; it was the first diesel locomotive to employ the technology. Although this technology was not featured on the original #103 demonstrator set it was included on the first production set completed in December, 1940; Santa Fe #100 previously highlighted.
Just as electric locomotives were efficient in using the overhead catenary for regenerative braking by returning voltage back into the system, dynamic brakes worked by using the traction motors to retard the train's progress.
The March, 1945 issue of Diesel Railway Traction highlighted the FT's dynamic brakes:
"The main generator is used to furnish excitation for the traction motors, which become separately excited generators. The main generator fields are controlled in turn by a hand-operated rheostat in the driver's cab.
The traction motor armatures are connected to the air-cooled grids mounted in the roof of the locomotive; motor-driven blowers which supply cooling air to the grids are connected electrically with the grids and so act as part of the load."
To prevent engineers from overloading the grids, or traction motors, a red mark on the dial of the transition meter, as well as an accompanying flashing light, warned of the maximum intensity of braking that was permitted.
This feature not only
prolonged the life of both the wheels and brake shoes but also allowed
the locomotive to hold back very heavy trains on steep grades for an increased level of safety (and it is still used in modern day diesels).
One of the FT's key selling points was its tremendous starting tractive effort; on average this figure was 228,000 pounds, higher than practically any steam locomotive type ever developed. Whereas a steam engine produces its greatest tractive effort at-speed, diesels generate their highest rating when starting.
The #103 set was so powerful it often pulled apart trains as crews were unfamiliar with the new technology and knowing just how much initial exertion to apply. The FT's four-axle, B-B trucks were a primary reason for this high adhesion; these trucks were not only equipped with traction motors on each axle (unlike the early "E's" A1A-A1A trucks whose center axle was unpowered) but also enabled the locomotives to place their entire weight on the driving wheels. The trucks were designed by Martin Blomberg, who adapted them from his successful A1A trucks used on the early "Es."
The FT's ability to not only demonstrate its superiority in main line service but also change more than a century of deep-rooted culture is a testament to the product General Motors introduced in 1939. The fact that the builder also accomplished this feat in such a short period of time is equally as impressive.
Another issue facing GM was illustrating how a four-unit FT set was actually a single locomotive and not individual units. Otherwise, unions would require each to be fully crewed, thus eliminating many of the FT's cost savings. To accomplish this, Electro-Motive constructed a cabless "B" unit that was semipermanently coupled to an "A" unit. This pair was then semipermanently coupled to another A-B pair for a complete 5,400 horsepower set.
Yet another significant hurdle was convincing railroads to completely change how they acquired new motive power by purchasing mass-produced locomotives that were practically identical except for paint schemes and other minor variations.
This was almost unheard of up until that time when railroads typically custom-designed steam engines to fit their specific needs, working in conjunction with the manufacturer(s). In other cases, company steam shops simply designed and built locomotives from the ground up. However, GM was so confident in its product it believed it could win over the skeptics and this belief proved correct, not only with the FT but also future models like the F3 and F7.

In the end several Class 1s, from the Missouri Pacific and Milwaukee Road to the Baltimore & Ohio and Boston & Maine purchased the FT. None were more enamored, however, than the Santa Fe, which acquired an impressive 32o examples between December, 1940 and August, 1945.
By the time production had ended in November, 1945, Electro-Motive had sold 1,096 units. It led to the later F3 and F7, models which saw even greater sales.
Today, five FT units are preserved:
