Adding Wings to the Iron Horse
“Once I built a railroad, I made it run, made it race against time. Once I built a railroad; now it’s done. Brother, can you spare a dime?” – Bing Crosby
In the early 1930s America’s passenger railroad business was in trouble. In addition to the Great Depression, the once dominant industry faced growing competition from automobiles.
It had been just 60 years since coal-burning steam locomotives and the transcontinental railroad had linked America’s east and west coasts. Now, more than 30 million cars, trucks, and buses were on U.S. roads. What would power heavy transportation?
Although railroad steam engine technology had advanced since the “golden spike” of 1869 in Promontory Point, Utah, locomotives still “belched steam, smoke, and cinders,” notes one railroad historian. “Passengers often felt like they had been on a tour of a coal mine.”
The railroads’ distillate-burning internal combustion engines of the day were heavy and troublesome. Primitive diesels had been used in switch engines from about 1925, but they were slow, explains Richard Cleghorn Overton in Burlington Route: A History of the Burlington Lines.
Burning fuels ranged from a low-grade gasoline to painter’s naphtha and diesel. Distillate railroad engines emitted an oily smoke and often produced only a single horsepower from 80 pounds of engine weight. These common four-stroke engines fouled easily and required multiple spark plugs per cylinder.
Even Bing Crosby lamented the fate of railroads in his popular song, “Brother, Can You Spare a Dime?”
But help was on the way for America’s failing passenger railroads. It would come from the U.S. Navy in the form of a diesel-electric engine…wrapped in a stainless steel Art Deco locomotive.
Petroleum’s Silver Streak
“Wings to the Iron Horse,” the passenger line’s advertisement proclaimed in the 1930s. “Burlington pioneers again — the first diesel streamline train.”
With the threat of war on the horizon, the U.S. Navy needed a lighter weight, more powerful diesel engine for its submarine fleet. General Motors joined the nationwide competition to develop a new diesel engine.
Seeking engineering and production expertise, in 1930 GM acquired the Winton Engine Company of Cleveland, Ohio. Winton, established in 1896 as Winton Bicycle Company, was an early automobile manufacturer.
The Winton Engine Company evolved into a developer of engines for marine applications, power companies, pipeline operators — and railroads. With GM’s financial backing, Winton engineers designed a radical new two-stroke diesel that delivered one horsepower per 20 pounds of engine weight. It provided a four-fold power to weight gain.
The Model 201A prototype — a 503-cubic-inch, 600 horsepower, 8-cylinder diesel-electric engine — used no spark plugs, relying instead on newly patented high pressure fuel injectors and a 16:1 compression ratio for ignition.
At Chicago’s Century of Progress World’s Fair in 1933, GM evaluated two 201A diesel-electric engines, using them to generate power for its “Making of a Motor Car” exhibit. The working demonstration of a Chevrolet assembly line fascinated thousands of visitors who watched from overhead galleries.
One visitor happened to be Ralph Budd, president of the Chicago, Burlington & Quincy Railroad (known as the Burlington Line).
Budd immediately recognized the locomotive potential of these extraordinary new diesel-electric power plants. He saw them as a perfect match for the lightweight “shot-welded” stainless steel rail cars being pioneered by the Edward G. Budd (no relation) Manufacturing Company in Philadelphia.
Edward Budd was the first to supply the automobile industry with all steel bodies in 1912. His success in steel stamping technology made the production of car bodies cheaper and faster. By 1925, his system was used to produce half of all U.S. auto bodies.
The Depression, however, put the Budd Manufacturing Company almost $2,000,000 in the red — prompting its fortuitous diversification into the railroad car market to generate revenue. When approached by Burlington President Ralph Budd in 1933, this Budd was ready.
Within a year, the two technologies were successfully merged with the creation of the Winton 201A powered Burlington Zephyr — America’s first diesel-electric train. It would change railroad history.
Art Deco Locomotives
The Zephyr rolled into Chicago’s Century of Progress exhibition on May 26, 1934, ending a nonstop 13 hour, 4 minute, and 58 second “dawn to dusk” promotional run from Denver.
Powered by a single eight-cylinder Winton 201A diesel, the “streamliner” cut average steam locomotive time by half. The Zephyr traveled 1,015 miles at an average speed of 76.61 miles per hour and reached speeds along the route in excess of 112 mph — to the amazement and delight of track-side spectators from Colorado to Illinois.
During its record-breaking run, the Zephyr burned just $16.72 worth of diesel fuel (about four cents per gallon). The same distance in a coal steamer would have cost $255. Construction innovations included the specialized shot-welding that joined sheets of stainless steel. The lightweight steel also resisted corrosion so it didn’t have to be painted.
Americans fell in love with the Zephyr. Four months after its high-speed appearance at Chicago’s Century of Progress, the streamliner made its 1934 Hollywood film debut, starring as “The Silver Streak” for an RKO picture. The Zephyr was loaned for filming – and the Burlington logo on its front was repainted to read Silver Streak. “The stream-lined train, platinum blonde descendant of the rugged old Iron Horse, has been glorified by Hollywood in the modern melodrama,” proclaimed the New York Times.
Although the black-and-white “B” movie came and went without making much of a splash, it has won its place in movie history as a rail-fan favorite, according to a 2001 article in the Zephyr Online. “It did have a lot of action, and the location shots of the Zephyr are an interesting record of this pioneer.”
The RKO film should not to be confused with 20th Century Fox’s 1976 comedy “Silver Streak,” which was filmed in Canada using Canadian Pacific Railway equipment from the Canadian, a transcontinental passenger train, according to the Obscure Train Movies website.
More than a Railroad Technology
By the end of 1934, eight major U.S. railroads had ordered diesel-electric locomotives. The engine technology’s cost advantages in manpower, maintenance, and support were quickly apparent.
Despite the greater initial cost of diesel-electric, a century of steam locomotive dominance soon came to an end. By the mid-1950s, steam locomotives were no longer being manufactured in the United States.
GM won the Navy’s competition for a lightweight powerful diesel — choosing the 16-cylinder Winton Engine Company diesel-electric to power a new class of submarine. In 1935, the USS Porpoise was first to join the fleet, where it served throughout World War II. Diesel-electrics power plants descended from the Burlington Zephyr would remain part of the fleet until replaced by nuclear propulsion.
A Zephyr competitor — the Union Pacific M-10000 built by the Pullman Car & Manufacturing Company — also appeared at the Century of Progress World’s Fair in Chicago. In fact, this aluminum streamliner was revealed six weeks earlier than the Zephyr. Originally powered by an inefficient four-stroke engine, the M-10000 would switch to the Winton 201A. Recognized as America’s first streamliner, the M-10000 was cut up for scrap in 1942.
The Zephyr (later renamed the Pioneer Zephyr) is on display at the Chicago Museum of Science and Industry.
