Red railway signal. This signal is used to warn train drivers. This is a two-aspect colour-light railway signal set at danger (red). The upper light (not lit) is green. The 2-aspect signals were among the first signals used on British railways,and are used in less complex situations than areas that require 3-aspect and 4-aspect signalling (which include amber lights).
