Hello!

I currently use Train Controller and Marklin Circuit tracks (the one with the toggle) when profiling my locomotives. I was looking for an alternative to the Circuit Track. The issue is at the very low speeds while programming, the toggle piece seems to lift the pickup shoe just for an instance, and because the loc is going at a very slow speed, the locomotive stops.

Would using the reed contact device be a better, more reliable option?

Open to any and all ideas.

Thanks!
Norbert

Thanks Peder,

I'm using C track. I do use the contact track method for train occupancy around the layout. I'm looking more for a momentary indication used for speed profiling that I have set up a separate track run for this.

Thanks everyone. I did look up the pictures by John at river6109 in your link for #1909, however my electronic experience is very limited, and very little to no experience in building these circuit boards. Are there any electronics OEM companies that sell these optical sensors already built for the model train customers? Thanking in advance.

Dear All -

Have a look at Geoff Bunza’s blog on this topic, link here. Good background on the topic of position sensing methods.
