I guess I should start calling it Bergen Light Rail since that is its official name in English.
Anyway, there is some maintenance going on in the tunnel so the train stops or slows down to a crawl in places. One such place is at the side track in to the depot. Usually, this side tunnel is completely dark but because of the work there all the lights are on atm.
Unfortunately the train didn't stop completely but I managed to get this shot through the window anyway
