Passenger service had been losing ridership to automobile travel since the mids, making faster, more efficient service imperative for railroads to compete.
Railroads needed to lower operating costs of passenger service and boost ridership with a more modern image for the traveling public, to restore profitability to passenger service.

The project hinged on two major elements, developing lighter railcars and developing an internal combustion driven power system adequate for high speed service.
In Ralph Budd met Edward G. Budd no relationan automotive steel pioneer who was founder and president of the Budd Company. Edward Budd was demonstrating his new Budd-Michelin rubber-tired rail cars built of stainless steel. Pneumatic-wheeled railcars never found popularity for actual service in the US — they tended to derail — but they demonstrated the successful construction of lightweight stainless steel unibody railcars.
Some power-trailer car sets in that series articulated with Jacobs bogies shared between cars embodied the basic elements of car construction that would be used to build a lightweight streamliner train.
Since the carbody was much lighter than similar cars, it would be able to carry a higher revenue load for the same cost.
On August 20,Earl J. In spot welding, the two pieces of metal that are to be joined are pressed together with an electrode on each side of the joint. A very high electric current is passed through the joint and fuses the two pieces of metal together.

The articulated design of some Budd-Michelin cars, with trucks shared between adjacent cars, presented another opportunity for weight saving pourquoi ne puis-je pas perdre du poids avec lchf the new train.
The articulation not only reduced the number of trucks under the train, but it also dispensed with the need for couplers between each of the carbodies, further reducing the train's weight.
The concept was used by Budd engineer Walter B. Dean to build a train consisting of three semi-permanently attached cars. The other major problem Ralph Budd faced was to find a powerplant adequate to drive a trainset at a speed competitive with the faster steam trains. The existing gasoline powerplants for motorized railcars were inadequate and gasoline engines showed limited potential for higher capacity hauling applications.
Contemporary four-stroke marine and stationary diesel engines had low power-to-weight ratios and were only efficient under a narrow range of operating conditions, rendering them unsuitable for rail transport. Spark-ignited petroleum distillate engines also suffered from low power-to-weight ratios along with being maintenance-intensive and smokey.

Their efficient operating range was also improved, owing largely to improvements in fuel injection developed by GM and Winton.
A diesel-electric system driven by a prototype of the new design was used to power General Motors' automotive assembly exhibit at the Century of Progress Chicago World's Fair. Budd saw the compact, efficient system in action, saw a major perte de poids burlington wi of his lightweight train puzzle fall into place, then approached GM about adapting their engine for rail propulsion. In a Century of Progress exhibit inspired the Zephyr streamliner; the following year the new Zephyr streamliner inspired the Century of Progress fair and the rest of the country.
Pioneer Zephyr cab with controls The exterior design of the train was left to aeronautical engineer Albert Gardner Dean Walter Dean's younger brother who designed the sloping nose shape, with architects Paul Philippe Cret and John Harbesondevising a way to strengthen and beautify the sides with the train's horizontal fluting. The streamlining extended to the undercarriage as well to reduce drag. He wanted a name that started with the letter Z because this train was intended to be the "last word" in passenger service; Budd and his coworkers looked up the last words in their dictionaries, but neither zymurgy nor zyzzle conveyed the meanings that Budd was looking for.
The name of the new train came from The Canterbury Taleswhich Budd had been reading. The story begins with pilgrims setting out on a journey, inspired by the budding springtime and by Zephyrusthe gentle and nurturing west wind.
Budd thought that would be an excellent name for a sleek new traveling machine—Zephyr. The second car consisted of a small baggage section and a short buffet and passenger coach section. The third and final car in the train, as originally built, was configured as half coach passenger seats and half observation car 12 passenger seats. As built, the train had 72 seats and could carry 50, pounds After a series of demonstration runs, the trainset was christened the Burlington Zephyr on April 18,at the Pennsylvania Railroad 's Broad Street Station in Philadelphia, Pennsylvania.
Following the Zephyr Budd built an identical trainset, the Flying Yankeefor the Boston and Maine railroad, and went on to build a series of larger and more powerful Zephyr trainsets for Burlington.
Promotion: "Dawn-to-Dusk" dash[ edit ] Cigarette ad showing the train and describing the run in The train made a "Dawn-to-Dusk" dash from Denver to Chicago on May 26,in a publicity stunt timed to coincide with the opening day of the Century of Progress fair in Chicago. The railroad spared no expense in planning the operations. All other trains along the Zephyr's route were diverted to sidings and the turnouts were spiked into the proper alignment for the Zephyr's run.
Track and maintenance of way workers checked every spike and bolt along the train's route to ensure that there would not be any problems, and temporary speed signs were installed along the route to warn the Zephyr's crew of curves that would be dangerous at high speeds. Stations along the route were protected by local police officers and members of the American Legion and the Boy Scouts of America.
The passengers, including "Zeph" the burro, that perte de poids burlington wi the Zephyr on the "Dawn-to-Dusk Dash" gather for a group photo in front of the train after arriving in Chicago on May 26, Riding the train were Ralph Budd, Edward G.

When asked about the burro, Ralph Budd replied "why not? One more jackass on this trip won't make a difference. More than two million people saw the train before it entered revenue service. Paul a full five hours faster than the Burlington's fastest steam-powered train.
Due to the Zephyr's success on this test run, the Burlington immediately ordered two more Zephyr trainsets that were dubbed the "Twin Zephyrs", starting the spread of the Zephyr brand.

Some of their early reliability problems were mitigated comment perdre du poids femme au foyer changes to individual parts such as pistons; other solutions had to wait for a differently designed engine. For example, the first generation of pistons in the Winton engine only had about 50, miles of useful life, later extended to aboutmiles.

This caused operating problems, as train lengths perte de poids burlington wi not be changed for demand and any single failure affected the entire train.

All following power units were separate from their train, although four more articulated and semi-articulated carsets were built.
