b. Subsidiary signals
Subsidiary signals which subordinate a main signal, do not protect a section, and forecast and repeat the signaling of main signals, in the outer area of main signals.
Application of subsidiary signals is as follows.
Repeating signal: Subordinating home signal, departure signal and blocking signal to supplement confirmation distance by repeating the signaling of main signals, in outer area of main signals.
Installation example of repeating signal is shown in Fig. 9-2.

Distant signal : Subordinating home signals, to forecast signaling of home signal, in outer area of home signal.
Installation example of distant signal is as shown in Figs. 7 and 8 of Automatic block system in 6-(1).
