The Silver Streak Zephyr was a train service of the Chicago, Burlington and Quincy Railroad in the American midwest.

On April 15, 1940 the Chicago, Burlington and Quincy Railroad inaugurated the Silver Streak Zephyr operating a Lincoln-Omaha-St. Joseph-Kansas City round trip daily.

The new train was named Silver Streak Zephyr for the train portrayed in the Paramount Motion Picture The Silver Streak, with the starring role by the Pioneer Zephyr.

For power the new five car lightweight streamliner was assigned a new EMD E5A unit developing 2,000 horsepower (1,500 kW) Passengers were obviously pleased with the new Silver Streak Zephyr as ridership showed a marked increase within days of the new trains entry into service.

The Burlington's days of ordering articulated equipment were over and no further cars of that type would ever be contemplated.
