Signals positioning - how to go about it Various possibilities and request for confirmation from the experts 1) At the entry and exit of a station - this one seems simple - need to position one at the entry of a station - Green for vacant station can enter / Red for Occupied do not enter - need to position one at the exit of a station - Green for time for train to start - can leave / Red for Not yet time to start 2) At the turnout - approaching the divergence - Which signal should i place here - Green/Yellow OR Green/Red OR Semaphore - What will it indicate 3) At the turnouts - there are 2 approach points - Do I place 2 signals for each approach 4) At the yard - where the main line diverges into 5 yard lines - Do I place 5 signals each facing out from the yard and 1 facing towards the yard Many other possibilities and options - I would like to understand in detail. My layout is taking shape and to give an idea - pic below of a draft - would have about 48 turnouts with 3 stations (2 platforms each with 4 lines)

Hi Deepak, You can find answers to all your questions in the Marklin signalling handbook. Signalbook 0340 (English).pdf (1,568kb) downloaded 293 time(s). |

Mostly Marklin.Selection of different eras and European railways Small C track layout, control by MS2, 100+ trains but run 4-5 at a time.

I am not sure if you are aiming for prototypical signalling or not. If so, then 'green' does not mean it is time for the train to leave.
An exit signal is often green already when the train comes in to the station to stop. The timetable determines if it is time for the train to leave. So a train may wait at a green signal until it is time to leave and then it will depart.
Obviously, if it is time to depart, a red signal will not allow the departure.
When there are curves in the track, a set of signals running across the tracks must be in a straight line. The prevents the driver from seeing the signals out of track order. |

Light or Semaphore - functionally can be equivalent - smaphore (the old tech) mainly now on branch lines without electrical often. If it fits the style of service/line size.
There are also the yellow/green aspects, which indicate proceed slowly - such as you are allowed to go but slower, such as taking turnouts to change tracks/direction, or at tight bends. Then if you want, there are also the pre-signals that inform the driver about the actual signal that they just cannot see yet due to obstructions/curves.
In German stations, at the platforms there are platform mounted departure signals (diagonal lines I think) that mimic the platform personels traditional waving of the green circle, to signal the train is ready to go (for when the loco driver may not be able to see down the platform as the platform personnel signal good to go (and whistle). That signals its time for the train to leave. That is, of course as stated, independant of the track signal which indicates whether pulling out of and crossing turn outs-joining the mainline has been cleared by the dispatcher (due to other traffic). |

I have never heard yet of a railway signal being green upon arrival at a station unless the train is meant to continue but for some reason has been told to wait by traffic control due to a train being in front and the distance between the trains is too short They try to keep a 2 minute headway between trains for saftey

You will see the exit signal is often green when the train arrives. The train then stops at the platform and departs when the schedule says it should. It makes perfect sense, and does not contradict a 2 minute space between trains. |

Signals are for safety, not scheduling. |

In Sweden I know of a train station that has a departure signal that shows green of the track after the signal is free. Then it's up to the driver to remember to stop at the station. I've been twice on a train that has passed the station. Then there's always a embarresed driver in the speaker systems and tells the passengers to take another train back from the next station. 😀

Here in Belgium this platform signal is a circle of green lights. Viesmann 4518 is a model of this so I suspect this is now the pattern in Germany too. Jabez |

Serge, I don't ride the SNCB much these days, but it is a circle of dot lights, not a cross.. Maybe they are white rather than green and I was misled by the Viesmann model. Jabez |

That signals its time for the train to leave. There are diagonal white lines that allow the conductor on the platform to see if the exit signal allows the train to depart. At larger stations with long-distance trains there are green circles at the exit signals - these are controlled by the conductor on the platform or the station personnel and instruct the train driver to go. The diagonal white lines mimic the appearance of semaphore signals. |

For Jabez  That's what I was talking about. If you click on the image, you will see how the signal works in the foreground and the second in the background Serge |
