| After its time on the Katy, the engine served at the Martindale Feed Mill in Valley View, Texas, where it moved hopper cars for the grain elevator. AR stands for Alan Ritchey, Inc., which owns Martindale Feed. The engine was eventually replaced, and Alan Ritchey, Inc., agreed to sell the engine to the Oklahoma Railway Museum, ensuring its preservation.
