@ Super: I was referring to the two more recent C58s; The Imperial Train and The Ginga Train. They and the C57s represent similar sized locomotives but the C57 is tender powered while the C58 is locomotive powered.
As far as I can tell, the primary reason for this is to allow a Plakid to sit in the cab of the C57.
