In this photo taken on Oct. 14, 2009, the trains of Keihin Electric Express Railway Co. Ltd. pulls in to Gumyoji station lit in blue light-emitting diode, or LED, in Yokohama, west of Tokyo, Japan. Alarmed by a rise in people jumping to their deaths in front of trains, Japanese railway operators are installing special blue lights above station platforms they hope will have a soothing effect and reduce suicides.
