I don't have those M manuals, so is there a place where i can see and study some simple schematics about stop a train at a turnout to let the other pass, or to stop a train at a station and then make him continue, etc?
Once again tks for your patience!
The older 446 Signal Manual is available to download from Marklin USA at this link....
ftp://ftp.marklin.com/pub/Old%20Manuals
Look under "Model Signal Booklet", download all the pages and see how you go - it's about 2.5mb in total but will be a good start.
Easier to answer questions based on what you do or don't understand from this starting point.
Don't be scared off by the older signals and track shown, the basic wiring and concepts have not changed.
You need to create an isolated section in your track - usually by interrupting the center rail at two locations (the start and end of the isolated section)
So if you can imagine a length of say 6 straight track lengths, and the middle two have the center conductor cut at the join with the two left track and the two right tracks....
| = track joins
X = isolated center rail
....
|------|-----X
-----|-----X
-----|-----|....
So there is still power at the left and right sections either side of the "X", but nothing to the area between the 2 "X". And when the train gets to this section it will stop.
Now you take a wire attached to the center rail anywhere between the two "X". If you join that to the center rail OUTSIDE either X, you will have power again to the isolated section and the train will start.
You could simply wire a switch into the connection between the isolated and powered sections and have a very basic manually controlled stop point.
But Marklin Signals already contain a set of switches inside which are open or closed depending on whether the signal is Red or Green. The signal may have red wires coming out from the switch or red sockets you can connect to.
The built-in signal switch replaces the manual switch I referred to above so when the signal is red, the switch is open, no power to the isolated section. Change to Green and the circuit is complete, trains will pass through.
So that is basically how to start and start trains with a signal (manually controlled).
The next step is making the operation of the signal automatic with a passing train. This is simpler, you are simply replacing (or duplicating) the old Blue control push buttons
with track contacts - either the 'flipper' type Contact Track (directional) or with a Circuit track using the isolated outer rail.
I have a newer signal manual here with some good diagrams, I'll see if I can find and scan the relevant pages which should help - a picture paints 1000 words as they say
Hope this helps
