Yesterday i did a 110 hauled n-wagen service without the steuerwagen. The interior lights were off and i couldn't find a way to turn them on. Is there a way to turn on the lights without the steuerwagen?
There's a panel on one of the ends of each N-Wagen that has light controls for the individual coach and the whole consist, similar to the Dostos.
The n-Wagen were not built for centralized electric power; each has its own generator and battery and each has to be switched on individually.
That is not true for the ones we have. The z in the naming of the wagons denote that they are equipped with a common train bus and no generators.
But the train lights are not powered by the train line power directly. They are hanging on the battery and the battery is getting charged by the train line. At least, the loco does not have a train light switch. The cab car has. Normally the guard/conductor is preparing the coaches, not the driver.
Actually I have to correct myself. The non-cab cars are only labelled Bnr, however they are visually missing the generators. Which leads me to another question. How would the cab car recieve its power when the cars inbetween do not have the train line? I think I remember having seen such a combination in real life, where one of the intermediate cars was a Bn (yes, no disc brakes and no train line).
After looking it up, it appears that later n-Wagen constructed from 1968 on did have train-line busses; but these all have the "z" designator. But one wonders if the 110 was equipped to operate it; when it entered service all DB coaches used generators.
