Have i missed something. Shouldn’t it be Danish signals?
This is the German portion of the route from Grossenbrode to Puttgarden before the tunnel so there are no Danish signals there.
Ask TS-Tools what signals are installed there, if necessary go through missing parts up to textures, then you will get a hint from which package what is missing.
That looks more like HV or KS signals.
If there are older KS, then KS from ELAP is also used.
Das habe ich nicht gefunden durch TS-Tools.
