Although described by Wes Barris in http://www.steamlocomotive.com/mountain/nyow.html (visited 17 Feb 2003) as "hard to maintain and hard to run -- they required two firemen", these Santa Fes nevertheless carried on until the 1940s. They had relatively small and short tubes and flues for the period. Perhaps the narrowness and shortness choked the immense firebox grate.
