Rescuers called to the scene of a train derailment found the train's engineer and conductor atop one of the derailed locomotives in an area surrounded by rising flood waters.
No one was injured in the late Monday night derailment of the Canadian Pacific train and the rail workers were safely rescued.
Railroad spokesman Ed Greenberg says the derailment was caused by a washed-out rail line. Five cars, four of them carrying ethanol, derailed.
Railroad inspectors initially reported none of the ethanol leaked, but Tuesday night the Iowa Department of Natural Resources confirmed ethanol and diesel were leaking into the Little Cedar River.
The DNR says one of the ethanol cars had been punctured, resulting in a slow leak.
