5001, Santa Fe, was built in 1949 by Pullman-Standard. It was 85' in length. In August, 1957, it was renamed to Atchison with the arrival of the new Budd built Santa Fe and Topeka business cars. The Lambert car is fairly crude by modern standards, but is the only model produced of this this business car. A close look at the model above shows the underbody to be installed backwards, yet many items have not been included.

Drawings, floor plans, and photos appear in the Ellington & Shine book on ATSF Business and Special Purpose Cars which is now out of print but scheduled for reprint by the Society. Ellington's drawings and photos are circa 1957-59 and serve as the plans for the Lambert model. Additional coverage can be found in Randall's Pullman Standard Library Vol. 1, also out of print but scheduled for reprint. His drawings and photos are as built and are slightly different from the model.
