Activating Safety Systems In Ice1

Does anyone know how to activate safety systems in the ICE1, so that the scoring system recognises it on Kassel Würzburg?

I’ve turned on sifa, pzb, lzb and I’m using AFB, but I’m still only getting 30 AP when driving. Have I missed something or is it a bug?

 

It's one of those routes where it does not score for using safty systems so gold is the highest you can achieve

 

IIRC, Kassel-Wurzburg is a TSW3 route, so it still uses the old scoring system that doesn't give a safety systems bonus.

 

Only routes from TSW4 have additional points for safety system

 

Thank you for explaining, really appreciate it
