A home signal is a signal that protects something. Be that a set of points, a crossover, a level
crossing or whatever, it is always protected by a home signal. If the signal does not protect
anything, it is not a home signal. The only exception is a neutral zone (or shunting limit) which
is protected by an Outer Home or Accept signal, which is fitted with a prohibitive instruction
plate.
