Märklin analog teppichbahn automatic overtaking

Two trains share an oval. When the faster train catches up, the slow train will automatically yield to a side track. Featuring proper tri state operation of a 7041 signal and speed reduction on the side track.

Wo ist der Teppich ?

[@jeffliick1690]

How would you make this work if you had cars with lights in them? Wouldn’t the pick-up shoe in the car trip the signal and mess this all up?

[@anderspedersen4783]

Yes, that wouldn't work.

Kann man da auch mal die andere Lok die andere entgegengesetzte Richtung fahren lassen geht das?

[@anderspedersen4783]

The wiring and the setup would need to be completely different if two loks should run in opposite directions. But it would certainly be possible.

[@wallasalzburg]

How did you realise that function? =)

[@anderspedersen4783]

wallasalzburg It’s controlled by the fernschalter you see nearest the camera. When the slow train enters the curve near the camera, it flips the entry signal to red and also trips the fernschalter. You can see the fernschalter flip on the video. The yield function is then “armed”. If a fast train approaches the curve before the slow train is out of the curve again, the fernshcalter now lets the fast train flip the turnout and the tri state signal, sending the slow train off to the side track. The fernshcalter is cancelled by a contact track at the curve exit. It looks convincing on the video but it only works well with carefully matched loco speeds, unfortunately.

How did you get the idea and how did you do it?

[@anderspedersen4783]

I think I got the 7041 signal secondhand and wondered how to deploy it realistically in an automatic fashion. The 7041 "proceed slowly" mode is prototypically used in front of deflecting turnouts so the layout had to feature a turnout. This idea is what I came up with after lots of thought 🙂
