The David B. Jones Special was a one-time, passenger train operated by the Atchison, Topeka and Santa Fe Railway from Los Angeles, California, to Chicago, Illinois, at the request of David Benton Jones. David B. Jones was suddenly taken ill with cancer at his winter home "Pepper Hill" in Montecito, California. This special rushed him to his Chicago physicians and surgeons at an average speed of . This run was completed three minutes faster than the more famous 1905 "Scott Special". Although not part of the speed run, the train continued on to David B. Jones' summer home in Lake Forest, Illinois.
Overall trip summary.
The train left La Grande Station at Los Angeles at 11:33 PM May 5, 1923, Pacific Time and arrived in Chicago at 12:50 AM on May 8 Central Time. The journey was completed "in exactly 47 hours and 27 minutes." The actual running time was only 44 hours and 51 minutes which deducts time spent for stops such as those for coal and water and the 55-minute delay caused by the breakdown of a Union Pacific locomotive ahead of the special at Nebo, California. The running time was therefore three minutes less than the "Scott Special". Thus, the average speed was and the average running speed was . It was "a phenomenal run when compared with the regular Santa Fe limited time of sixty-eight hours and thirty minutes." The $11,000 special thus saved about 20 hours over the time of the regularly scheduled train. ($11,000 is equivalent to $ in present-day terms.) "Mr. Jones' daughter, Gwendolyn Jones; his brother [Thomas D.], a doctor and two nurses accompanied him on the trip."

After arriving in Chicago.
"Upon arrival here [Chicago] it was switched back over the Northwestern track to Lake Forest, arriving there at 3:46 p.m. This switchback, however, is not counted in making the record."
