Although the question in railroad signaling between the system of time intervals and that of space intervals has been universally decided in favor of the latter, yet there are still some very important matters regarding signaling which, on account of fundamental differences, may be worthy of a detailed discussion. The first point relates to the use of colors for night signals.
