Light signal decoder (2011 series)

Light signal decoder are the most important application for decoder of the Z1-series (standard and all-in-one classes). Before using them on the model railway, they need to be configured. In the simplest case this is done with the programming button. However, often an additional programming with configuration variables is required. If signal aspects should be displayed, this programming can get an extensive job. You can manually configure the decoder yourself, or you acquire a pre-configured Qdecoder-light signal decoder and save the elaborate configuration of the configuration variables.

Qdecoder have some characteristics that distinguish them from other decoder on the market:

  • They can generate all signal aspects. No exceptions were discovered so far.
  • Signal aspects can contain flash or pulse operations. The operation mode can be changed depending on the signal aspect.
  • Signal lamps can gently fade in and out without blanking interval. This blending creates a prototypical cross fade from one signal aspect to the next.
  • Further switching commands can be received during the switching of a signal. The signal blends smoothly to the signal aspect of the last command received.
  • They can be switched with function buttons of locomotive addresses.
  • A switching command can trigger an independently running sequence of signal aspects .

CV sets for light signal will be constantly enhanced. Especially pre-configured decoder are available in the light signal decoder shop for the following signal systems:

RailwaySignal system Characteristics
DRG / DB 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.
British railways under development
Dutch Railways (Niederländische Staatsbahn) NS-signal system
Belgian National Railways NMBS-signal system
Polish State Railways PKP-signal system
