The first thing a visitor notices is that nobody runs for the tram. The next one is already on the board, and it is never far away.
A timetable you can memorise
Lines run at fixed intervals that repeat every hour, so the departures at a stop are the same minutes past the hour all day. People stop reading the timetable after a week. That is the point.
Priority, not speed
The trams are not fast. They are given priority at traffic lights and their own lanes on the busiest streets, so they are rarely late. Reliability turns out to matter more than speed.
