@lynnesbian Oh hey! I'm the person who originally submitted this to reddit.

As far as I know, this rule is no longer in place. It still shows up in some recent-ish documents (like [1]), but a train driver I know showed me a screenshot of a document explicitly stating that this paragraph was made obsolete.

It also doesn't show up in the current R 300.5 anymore. [2]

@lynnesbian I think the original limitation was caused by mechanical counters with eight physical bits (so, not actually software), which have now been phased out.

Otoh, the German LZB linear train control is 8-bit to its core. One sector is up to 12.7 km long, 127 × 100 m loop sections, for signed 8-bit position counters.

@draemmli thanks for clearing this up! i managed to find a slightly more recent document mentioning it, but you're right, it seems to have disappeared now
