Cold and Blue...Safe Handling Rail yard in Auburn, Me. Why does this sign has a blue light on it? mabye to just show up better? Updated 5-13-08 The blue light is a warning to all that work on the railroad that no movements can take place untill the light is removed, usually by the person that placed it. You will often see blue marker or light protection on trains that workmen are under, etc.
