FROZEN TRAIN
Frozen train brake system being de-iced by a rail worker. Most de-icing materials are salts that melt ice and snow by lowering the freezing point of water below 0 degrees celcius. A more simple method is to spray the ice with hot water. Photographed in Canada. (KEYSTONE/SCIENCE PHOTO LIBRARY/TONY CRADDOCK)
