Yesterday, I took out the 146 on HBK. I did the earliest service available in the 146 timetable. Tried to light up the passenger lights with the button in the 146 cab. No go. Got out the cab, walked over to the back of the train where I entered the dosto cab car. Tried the button there, also no go. Only way I could get them to work was lighting them up using the button on the passenger car wall. Had to turn them on car per car.
In the car there’s two button, one to turn on the light on this one or the other on all the others coaches but on the 146 have you tried turning on the train line which is the switch next to the MCB one ?
