Examples for use of protection signals

Example 1: Dividing a station track into sections

This allows for example to place two trains one behind the other on a single track.

Normal position

Beispiel Schutzsignal

Note that the backboard of the distant signal »r« (on »A/r«) has a white border. This indicates that the next signal can (but not must) be a protection signal.


Normal entry

Beispiel Schutzsignal


Entry into an occupied track

Beispiel Schutzsignal

Depending on the distance between the entry signal »A/r« and the protection signal »Sch 301« there is a speed restriction applied (even if there is no diverging route set). In this example 30 km/h.

up

Example 2: Complementation of group signals

A group signal is an exit signal which is valid for more than one track. In this case additional protection signals are provided at each track. Such layout is for example found in yards.

Beispiel Schutzsignal   Beispiel Schutzsignal

Note that the signals »Sch 203« and »Sch 205« are combined with (fixed) speed indicators.
