Thanks guys, all true!
I can either be at less than 95 km/h since (as I often state myself - an airline captain, bus driver or train driver should know his route), or as Tilmann explains (and if I understood this right) - use PZB 85 (Obere). I thought of this before setting off, because I only drove a light container train, "Containers to Singen", modified to use the BR189 expert line.
Otherwise, I now drive confidently with PZB 70 and heavy freight trains, finally knowing what speed I should have at each magnet. It helps a lot watching a video now and then, and also have the PZB quick reference always handy in my cocpit.
PS, Tilmann: I understand your English just fine, being used to tech German from my time at NSB, and being a sailor
