I am installing brake modules on 9 tracks distributed over 2 stations with a module at each end.
And here I am asking for "moral" support, as there are 2 tracks, that do not quite live up to an info. track (9cm) + the normal braking distance (90cm) + the dead rail (18cm) at both ends!
Then you see problems in me moving info. track forward in the direction of travel, the train group, which runs from left to right - and braking has been judged - saw that the locomotive first encounters info. the track, and afterwards runs over info. the track for the opposite direction (it is of course not activated), that track has instead become part of the deceleration. It is a Märklin AC, the locomotive is at the front with the drag shoe.
It will provide enough space for max. 90cm deceleration …..
There will be a drawing, that should show how. |

I have promised drawing, but how to get a Word document in ..... So I had then a foto in stead, but now I have picture in my dashboard, but can't find the trick to post it.
Here is the picture, but it is for the Southern Hemisphere  |

Is it 2 tracks you show up in the picture or just one with brake modules in both way? |

Yes
It is just one track, with braking stop in both ends.
The whole story is for me to find a bit more length on a track, that isn't long enough for my regular setup where it's 90 / 900 / 180mm, and that's why I want to shift the registration track into the range for the opposite movement.
And basically the whole question, so I hope that someone will come with an input |

What i can see the rail does not work as brake module for the 3 rail locomotives.
It can only work via pick up shoes because it´s power feed that brake modules can work.
In the 2 rail system it is right or left rail (depends choice) as the power feed. |

I assume that when a section with a brake module is not activated, it behaves like normal rails.
So when a locomotive runs from left to right (brown), part of the blue direction (which is not activated) is used, so that the short registration track for brown is an isolated part of blue's braking distance + brown's braking distance is also increased with blue's isolated recording track.
It's hard to explain, but it's even harder to do, as it turned out, that a platform is so stuck, that it will be destroyed, if I want to remove it!
So right now I am mostly inclined to reduce the braking distance from 900mm to approx. 800mm, and then when driving, find out if there are individual locomotives, that need to be reprogrammed. |

Correct, but if you enlarged my picture is as your screen print.
So thank you for your help !
But how to get the drawing right from the beginning was beyond my abilities. I was just happy that something came in!! |

There is also a 2nd option …..
Instead of having 1 registration rail for each direction, can I settle for 1 piece 90mm?
Again, the premise is that only one direction must be activated.
Or have I misunderstand something? |

I see a fault and you must feed power between two brake areas.

Thanks for your prompt reply.
A clear no sounds convincing, but I will still try to discuss a little for my last proposal!
My first assumption is that if the 3 section area is not affected then all 3 are normal rails.
If this is correct, then it is the brake module that is not involved in braking that will behave strangely when the common 90mm rail "sends" an impulse for braking in the opposite direction.
If it does, then you are definitely right.
Then you write that there must be "normal" digital power on the middle rail, and here you can say that that side has power from the other braking area, but it is not in operation.
I've just checked the rail that's in the middle, and it's a 900mm flex rail, so I can/will try the theory (here K rails are nice and easy to make isolated sections just by cutting the conductive part on the back), if it doesn't quite being punctured by You …. |

The simplest solution for bi-directional braking module is from www.bogobit.de. The bogobit Bremsmodul Classic bistabil works like a charm and I use it for bi-directional applications on my layout.

Thanks for the reference to Bogobit, and the large number of different options, which I'm having a hard time to evaluat and understand. But it doesn't matter to me either, since I have already bought 17 pieces of a type like Uhlebrock 44200. They were made here in Denmark from Litra.dk ( https://www.litra.dk/ ). So back in the "track", where the next step will be to make and test a common registration rail of 90mm, which must work in both directions. I'll be back when it's tried! |

Maybe a little off-topic...
Have you tried by use ABC for the Märklin tracks?
I am not really sure if you have other competitors locomotive which do have ABC technology support?
ABC are cheaper way but Märklin does not support this. |

Sorry, but I don't think so.
But the guy, who made the 17 pcs., talked about the ones he made could also work on a completely different principle !
But I must confess, I didn't listen enough....

Then the common info. rail is tested, and it has caused problems both times with a short circuit.
I have not dug further down and have decided, that this is not the way!
So up with the flex rail and made 2 insulated sections around the middle one with digal current (all 3 are 90mm long).
In order to get enough braking distance, both dead rails will for the time being be part of deceleration, and then I have to see if I tweak the setting of the locomotive decoder.
It will be tried tomorrow because now I've had enough of those brake modules and it's only the 3rd and there are 6 more tracks with 2 modules at each end.
A good thing is that it is raining a lot in Denmark for the moment !!

The 3. is now running with a 90mm center with “normale digital” power and with no dead ends, but it give a bit more bracking length ….
More info will follow, when it used with longer trains … |

I am not sure what you are doing but it seems you fail about your test. I did draw at picture for you and this is what it happens when you use brake modules in both direction on the same track. 1. When you drive in opposition signal A the signal B must show green so you can use brake modul for the signal A. 2. When you drive in opposition signal B the signal A must show green so you can use brake modul for the signal B. Please be attention about isolate your track area for the brake sections.  |

Thanks for your thoughts & drawing. This is exactly how the two mentioned tracks have been arranged with 90mm digital in the middle followed by the 3 sections. However, it is with the exception that "Stop section" became part of the braking. So no Stop section ! This makes this section longer than all other decelerations on the entire track, and then I have to see how it ends with the different locomotives and there different carriage lengths, since I am also not able to set the deceleration equally on various locomotives. Stop can be easily reinstalled as only a few wires need to be moved. Green at the entrance will normally be controlled by my CS3 (but green/red can also be changed manually). If there is no change to green where "Stop" has been removed, a short circuit will occur, and in the long run it might cause too many problems ! So now it needs to be re-established with ballast / fallen trees and figures + 2 dwarf signals on a track that never had a signal. They are homemade and are 6.5mm high and have 3 LED lights that change together with the brake modules. After this post there will be a picture .... |

Maybe you should try use CS3 and L88 with contact tracks as brake module? I know there are macro and memory to set your train set to use a track occupation? |

With purchase of 17 moduls - 8 allready installed - it first happen with layout .....
And at the age of 78, it will probably not happen until the next life |

 This is the home-made dwarf signal, that is supposed to be a track for freight trains. It connects the brake modules and is illuminated with LED smd 0402, and they are inserted small pieces of 1.5mm brass tube. The plate is laser cut 1 mm MDF plate |

My goal is set and is for me crystal clear... The future is with the new brake modules. Now 4x 2 have been installed on the first station and ballast etc. must be re-established before work is started on the larger station. And occasionally I also have to play with the train, so that the track doesn't get dusty! Edited by user 30 June 2024 20:42:45(UTC)
