Im just getting to grips with the German Railways. And I'm quite confident with passenger workings. But under Freight! what are PZB what are the limits? As I keep getting flagged by the system. Kind regards
Check out the guide in my signature. For example, the heavy Habbiins train (2nd service from the top, although it is recurring) will be in G-brake on all vehicles (that means you need to move the GPR switch at the back of the cab to G). This also means that the PZB mode must be U (move selector to U on the right side, under the desk. Lastly, since the BrH (sum of brake weights divided by train weight) is so low (49 with -25% factor due to G-brake) the train is limited to 80 km/h.
While that is correct for operating that train, PZB doesn't enforce it. PZB only requires the Mode U restrictions (105 km Vmax, 55 w/i 35 seconds after a 1000 Hz etc). The magnets don't know what your brake-weights are.
