I read once in a National Geographic about an industry in India that hired some elephants and their handlers to switch their small yard while the industry's small switcher was laid up for repairs. When the switcher came back, the industry mothballed it. They liked the elephants better. Each elephant could handle as many cars as the switcher could, PLUS the elephants could throw the switches with their trunks!
Well, I suppose Trish the Work Triceratops could double as a fork lift.
