I am rebuilding an old Marklin system, born in 1957 by my father, then grown year after year; after his death in 2005 the whole thing ended up dismounted and stored into boxes. In 2011 I made a first trial of rebuilding it adding some C-track pieces and a Mobile Station but again for lack of space it ended up stored inside boxes. Now having moved to a larger apartment with some very wide windowsills, I rebuilt the model, spread over two connected windowsills; the big problem was: how to control the ten turnouts on M track while avoiding the tangle of wires? Was it possible to digitize the turnouts by mounting modern Märklin 74462 decoders and Märklin 74491 mechanism for C track? It was not so easy but I finally succeeded, even by recycling the cardboard and plastic bag from the packaging, electrical contacts had to be soldered with tin, as seen in the two photos. Now the swap works perfectly in the sense that after 48 hours it has not yet missed a shot. http://foto.bonavoglia.e...20M%20digitalizzato.jpeghttp://foto.bonavoglia.e...0dx%20M%20operativo.jpegI imagine others had already done this, and I would be curious to know the solutions adopted.

No, not I. Good work!I use an m83 decoder for all my turnouts C and M. My M ones are flat on top.

Hi pBonavoglia This is great. Märklin did it in 1989 I think with its digital starter set 2602. The switches and uncoupler, were fitted with a little PCB similar to the decoder you are using.  The fixing to the track bed was made using thick, double-sided adhesive, I think. You could use this too At the time, the switches were fitted with a bottom, sheet metal protection Cheers Jean |

I control couple of dozen M switches with old k83s. Cheaper than new m83 (buy on ebay), so just install below base board of closeby switches and no need to use all 4 ports with long wires. The 260x solution is rare and seemingly not continued by Märklin. Ben Edited by user 05 June 2023 01:14:04(UTC)

Hi
Ben you are right but when doing a carpet train / floor train, integrated decoders inside the track piece adds much more fun.
Yes, on the other hand, having integrated decoders on a permanent layout is not good because, more expensive, dfficult to maintain, etc.
Just my opinion

I have some that I acquired as part of 'junk' auction lots. I'll need to dig them out to find the catalogue numbers, but the parts are somewhat buried at the moment.
