Home Signal/distant Signal (H/V)
The most common system is the H/V (Hauptsignal/Vorsignal) system which consists of home signals and distant signals. Depending on the technology used in the signal box, these signals may be indicated by semaphores or colour-light signals. The colour-lights show the same light patterns the semaphores show at night.
