Bob Saar for The Hawk Eye The Mark Twain Zephyr was one of the premier trains on the Chicago, Burlington and Quincy railroad when it was put into service on Oct. 25, 1935. Its lustrous stainless-steel design made it clear the shovel-nose locomotive was new and modern. Named after author Mark Twain, the train ran between Burlington and St. Louis through Hannibal, Missouri, Twain's hometown. Built by the Budd Co., locomotive No. 9903 was named Injun Joe, the bad guy in Twain's seminal novel, "Tom Sawyer." Likewise, the three cars were named after Twain characters: Becky Thatcher, Tom Sawyer and Huck Finn. The Mark Twain was christened in Hannibal by Twain's granddaughter and final descendant Nina Clemens Gabilowitsch.
