HV-signal system
|
The HV-signal system (Hp-main signal and Vr-approach signal) was developed before World War II, but only widely introduced after it. Its use is mainly limited to the western part of Germany (Deutsche Bundesbahn). It is a classic approach/main signal system. The main signal is announced by a approach signal which is about a kilometre before the main signal. |
DR |
Hl-signal system (-> Flyer)
|
The Hl-signal system was used by the Deutsche Reichsbahn in the former GDR, but is still found today. It has signals that contains a signal head with the main signal aspect and the approach signal aspect of the next main signal. |
DR / DB |
SV-signal system |
The Sv-signal system was introduced in the late twenties by the urban railway (S-Bahn) in Berlin. SV stands for signal connection (SignalVerbindungen). This system was the first to show the main aspect and the approach aspect of the next main signal on one signal screen. This idea lives on in the present combination signals. |
DB (new) |
Ks-signal system |
KS means combination signal (KombinationsSignal), that is, signals show simultaneously the main and approach signal aspect. It was introduced by the German Railway (Deutsche Bahn) as a replacement of the predominant HL and HV signal systems and is used at all new constructions. It replaces existing signal systems during modernizations.

Swiss Railways (Schweizer Eisenbahngesellschaften) |
Dwarf signals |
Dwarf signals are used for control of shunting operations. |
Signal type L (-> Flyer)
|
The signal system L is the traditional light signal system of the swiss railway. Of particular interest are the combination signals that can represent both approach and main signal aspect. |
Signal type N (-> Flyer)
|
The signal system N was introduced in 1986 as light signal system by the Swiss Railway. |
Austrian Federal Railways (Österreichische Bundesbahn) |
ÖBB-signal system (-> Flyer) |
The light signal system of the Austrian railways has indeed a certain similarity to the German H/V system. However, it has undergone a number of specific enhancements in recent decades. |
Dutch Railways (Niederländische Staatsbahn) |
Sign. system 1946 |
The signalling system of 1946 was introduced after 2nd World War and was developed from night semaphore signals.
|
Sign. system 1955 |
The signalling system of 1955 was slightly simpliefied compared to 1946. With additional flashing signal lamps the signalling opportunities were enhanced.
|
Belgian National Railways |
NMBS sign. system |
The Belgian signalling system has some specialties, e.g. the different signalling modes for both tracks of a two-tier track.
|
Luxembourg |
CFL sign. system |
The Luxembourg signalling system is comparable to the german HV-signal system. |
