A Ks signal with a speed indicator should be added.

Also to be considered: digiline interface for Ks signals to set aspects independent of interlocking

Related discussion on the mailing list:


I would indeed prefer just fully implementing the Ks signal spec. Signs are signs, they should not be dynamic.

This means: Add another type of Ks main signal that includes a Zs 3 speed indicator. This kind of signal can then be employed where required. Everything else is already implemented, especially the signal aspect system already supports it.

For context, here's the official "Signalbuch" of the DB: https://www.bahnstatistik.de/Signale_pdf/SB-DBAG.pdf
