In 1934, the Union Pacific (UP) introduced the Streamliner, M-10000 later renamed City of Salina. It was an ultramodern, high-speed, richly furnished, air-conditioned diesel train. Dining cars used fine china, silver and linen. Sleeping cars featured roomettes complete with bedrooms, private compartments and drawing rooms. Never had the American public seen such luxury in passenger rail travel, a standard which would last another 40 years.
