The Pioneer Zephyr is a diesel-powered trainset built by the Budd Company in 1934 for the Chicago, Burlington & Quincy Railroad (CB&Q), commonly known as the Burlington Route. The trainset was the second internal combustion-powered streamliner built for mainline service in the United States (after the Union Pacific Railroad's M-10000), the first such train powered by a diesel engine, and the first to enter revenue service.
The trainset consists of one power/storage car, one baggage/RPO/buffet/coach car, and one coach/observation car. The cars are made of stainless steel, permanently articulated together with Jacobs bogies. The construction incorporated recent advances such as shotwelding (a specialized type of spot welding) to join the stainless steel, and unibody construction and articulation to reduce weight. It was the first of nine similarly built trainsets made for Burlington and its technologies were pivotal in the subsequent dieselization of passenger rail service.
Its operating economy, speed, and public appeal demonstrated the potential for diesel-electric-powered trains to revitalize and restore profitability to passenger rail service that had suffered a catastrophic loss of business with the Great Depression. Originally named the Burlington Zephyr during its demonstration period, it became the Pioneer Zephyr as Burlington expanded its fleet of Zephyr trainsets.
On May 26, 1934, it set a speed record for travel between Denver and Chicago when it made a 1,015.4-mile (1,633 km) non-stop "Dawn-to-Dusk" dash in 13 hours 5 minutes at an average speed of almost 78 mph (124 km/h).[5] For one section of the run it reached a speed of 112.5 mph (181 km/h). The historic dash inspired a 1934 film ("The Silver Streak") and the train's nickname, "The Silver Streak".[6][7][8][9]
The train entered regular revenue service on November 11, 1934, between Kansas City, Missouri; Omaha, Nebraska; and Lincoln, Nebraska. It operated this and other routes until its retirement in 1960, when it was donated to Chicago's Museum of Science & Industry, where it remains on public display. The train is generally regarded as the first successful streamliner on American railroads.[9][10]
