@lynnesbian could it be a hardware issue? The sensor on the track only having one byte for counting.

@palinor5
What about more than 256 axles? In the original instructions, there is no hint of an overflow, just the exact number that is not to be met.

@datenhalde Maybe after counting to 255 the axle 256 sets the whole thing to 0 - so no more train on the tracks. Axle number 257 and following would be recognised as a train again.

@maikek yeah, we can agree on that. But why even counting, then? Making sure simultaneously that all cars left a segment by count comparison?

Maike

@datenhalde That would be my guess too. When I talk to my brother next time I will ask him - he works as an engineer in that area.

@maikek @datenhalde Yup, that's how the "track is occupied" is working if you use axle counters.

You count-in on entering and on leaving the track again you count-out. As long as your counter is != 0, the track will be marked as occupied for the interlocking system. 🤷🏼

@maikek @datenhalde Sometimes these systems also miscount, leading to the track being still occupied from the systems view, when it's actually not anymore.😶‍🌫️
That's then a case when the next train will be sent in "on sight" and has to report back. 🕵️
Then the dispatcher can reset the counter for that track. 👍🏼

@palinor5 According to this it was a physical device with 8 "bits", but they've been phased out, so the no 256-axle train rule has been removed.
