You have Problems without enough Brake %. When you take down this Brake Settings on PZB, you gone down with brake %. To use up setting, you need over 111 Brake % ... Normal only trains for passenger or special cargo wagons, or empty tank wagons with manuel load settings. Then did you have light to mittle weight freight trains, that use normal the middle PZB Setting. Then you have normal a Speedlimit from 100 or 120 KM/h ... You are need brake setting 66-110 % ... Normal as enginer, you brake early down, because you know your routes and you become not a influencing. By advance notice 90 you drive under 105 KM/h, by 80 KM/h under 95 KM/h, then you have no influencing.
This Brake % are more for Warn Signal to a Stop Signal for example, that you not see it early enough, that your train be can stay befor you come to a zone, who is risky (crash into other train....) ... It have more problems, when you drive under 65% ... so you goes to down setting, with 55 KM/h, and self by 70 KM/h you must go down to under 55 KM/h ... That is only, because for warn signals announcement for example stop on next signal, that you have enough time to brake with a big weight freight train. Normal only max Speed 80-100 KM/h and over 1800t in Germany. (Exception Special freight cars for weight trains, coal, iron ore or other one)
