Now it looks like a steam locomotive on the outside, but inside it's actually a diesel. (Kind of like what Six Flags Over Georgia did to their two steam locomotives this past year.)
This is a picture of the of miniature train back when it was still steam powered (from bgwfreak's Carowinds pages)
I think the miniature train was converted to diesel when the park removed the big Carowinds & Carolina RR steam trains in 1976, because all the park's locomotive maintenance equipment was sold off at that time.
