Have some problems with the BR143. It happens several times in different scenarios after a normally ride with some normal stops in stations, that suddenly after stopping in a station, that I can not drive further. I raise the drive lever (for example to 60km/h; the blue bar in HUD is rising too) but the train does not accelerate. I had all brakes released, I repeated apply and release brake, several times (including orange button in the cab). I´ve done additional the procedure as in the tutorial for the BR143 after emergency stop procedure, but it don´t work. Tried too Main switch off - on, Panto down - up; I gear up the whole lok, doesn´t help. Is this a bug? Or do I something wrong?
