After 21:00 the line is very quiet, so we are closing the rear tram after 21:00. We will continue to run with two linked trams. After all, we are keeping a close eye on the number of travellers. If it becomes too busy, we will open up the rear tram again. In that case, you will again find the conductor in the rear tram.
Keep an eye on the travel info displays at the stops. These indicate whether you must board in the front or rear tram.
