i know there are many uncontrollable/unsolvable bugs on safety systems on this game. no intended to blame on devs, but if we cannot overcome it, at least there should be detour for it i think. german loco's PZB usually turns off or became null status after save and load. to activate this on mainline, slowing down to 45kph > Turning off and on PZB > riding 45kph until 70/85 releases is needed which is obviously not comfortable. so buttons forcing PZB to be turned on for normal 55/70/85 sign would be nice to avoid this maybe Ins/Home/PgUP can be allocated, i think?
