One passenger suffered cuts and bruises. Witnesses said some passengers jumped off when it was about to crash.The engineer, 67-year-old John Forsythe, was thrown from the train. Forsythe worked at the zoo for more than two years and was a locomotive engineer for a conventional railroad for 41 years.
