Number 311 is the engine that pulled the famous "KATY Flyer," a commemorative train which consisted of a unique series of historic railroad cars:  Caboose#1, Box Car #12321, Coach #10 and Flatcar #12145. This unit of engine and cars was named after the MKT's St. Louis to Texas passenger train. The #311 engine (formerly No. 200 before being renumbered and repainted) was originally built to burn coal, but it was converted to burn oil in 1923 while undergoing an extensive rebuild. Engine #311 is the sole surviving MKT (KATY) steam engine. Donate to the #311 restoration here!
