An intermediate signal (abbreviation Zsig ) is a railway signal and is one of the main signals . It is set up in extensive station areas between the entry signal and the exit signal and delimits a part of the station within the station. Intermediate signals can have the character of entry, exit or block signals, depending on their position in front of route convergence or separation.
The Deutsche Bahn AG signal book states the following: Intermediate signals are the main station signals that are not entry or exit signals.
Your subsequent turnout area extends to the next main signal or to one in front of it - if there are several, at the last - usual stopping place of the train. In some constellations, a signal can be an exit signal in one direction (e.g. in the case of a branching route), but an intermediate signal in the direction of the other route. This is shown accordingly in the book timetable. This also applies to exits on the opposite track. There in the book timetable z. B. stand: "Zsig, on the opposite track Asig".
In Switzerland these signals are therefore (consequently) called track section signal .
