The Lincoln-Kansas City route was previously operated by steam power, and because of the expense it was running at a loss to Burlington. This route was the perfect candidate for the new diesel powered 3 car Zephyr. Soon Burlington was operating the route at a profit, and the Zephyr, one of America's first Streamlines, became a rousing success. Soon other Zephyrs were added to Burlington's fleet, and the Streamliner era began. Line after line replaced their fleet of heavy-weight steam powered trains, to the faster, more elegant, and extremely popular streamliners. By the 50s, this train included a Parlor Car, Dining Car, and Reclining Chair Coaches.
