Three freight trains collided in a rural part of the U.S. state of Indiana, starting a fire and injuring two of the six crew members involved. One of the trains, carrying mostly empty ethanol tanks, was stationary when it was hit in the back by another. A third then ran into derailed carriages on the parallel track. Local officials said there was no spill of any hazardous material from the wreck. Nevertheless, they ordered the evacuation of several dozen houses near the crash site as a precaution.
