The only time that the UP "coal turbine" made successful runs was when it was burning heavy oil (Bunker C). They were never able to successfully separate the fly-ash out of the flame stream, thus the fly-ash kept eating the turbine blades. When I was there, in Omaha (spring/summer of 1964), delivering EMD GP35s and DD35s, the big coal turbine never moved from its storage track.
