A PZB 70 question.


Abonniere unseren Kanal auf WhatsApp (klicke hier zum abonnieren).

    When driving with PZB 70 with a speed of 100 km/h and approaching a yellow speed sign 80 km/h, must I really brake down to 70 km/h? If I dont, I get a zwangse. I find this to be strange. Why down to 70 when I'm supposed to go down to 80? This happens at first 80 km/h sign after leaving Villingen. It also happens (too much) in TSW.

    Hello,



    in that case there is a speed test section which operates at more than 95 km / h. The following monitoring curve requires halting, better still under the monitoring speed, so here 65 km / h. If you know that this signaling comes, you just slow down to about 90 km / h, then you get no influence. In the lower train mode, I would even slow down to 55 (50) km / h.
    So I drive under the monitoring speed "95", I get no interference and can easily decelerate to only 80 km / h

    For many Signals you will have a GPA (Geschwindigkeitsprüfabschnitt) which would check what speed you are currently at, and whether to give you are 1000Hz or not. The GPA for an upcoming 80 km/h speed limit would check for 95 km/h. So if you do 95 km/h or more you get a 1000Hz restriction, while you will not get it, when you are doing less than 95 km/h.
    If the signal does not have a GPA you will always get a 1000Hz when a speed restriction is coming up.

    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)


    I hope you understand my english :D to far away I have use it :D ... sorry.

    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 :) .
