smoking section with seats for 20 passengers. Third and last was a 31-ft. compartment with seats for 40 persons, and a solarium lounge with chairs for 12. Before the Pioneer Zephyr, the travelling public knew only ornate but gloomy railroad car interiors. All that changed with the high-stepping Zephyr. Each compartment had a distinctive colour harmony coordinating wall colours, window drapes, upholstery, and floor covering. But more important than the Zephyr’s looks, were the uplifting effect it had on a mid-Depression America and its effect of reaffirming the faith of the people in the free enterprise system. A tradition established, a future defined In addition to its technological achievements, the Pioneer Zephyr led to a revival of the public’s interest in rail passenger service. Settled comfortably in the welcoming arms of the modern train, thousands of Americans watched the nation’s prairies, mountains, and forests fly by. Glamour queens of the era liked nothing better than to make a grand entrance into town by rail, greeted by crowds waiting on the station’s platform. Stainless steel remains a cornerstone material in modern rail transport. It is the standard material for rail applications all over the world especially in Japan and the USA. Modern technology developments and the importance of life cycle costing, make stainless steel an attractive option for rail cars. Today stainless steel is used in a wide range of railway applications. Regional, commuter, metro, underground and light rail trains depend on stainless steel for solutions. Material selection and design criteria are affected by the specific operating conditions and many of these are met by stainless steel. As such, stainless steel should be used whenever corrosion resistance, fire safety, ease of cleaning, minimal maintenance and visual attractiveness are key requirements.
