>>1044883A few decades ago, trams didn't have priority signals at intersections, but had their slots integrated in a fixed cycle together with slots for car traffic and crossing pedestrians.
For that, it was better to stop before and let the passengers board while waiting, rather stopping twice to wait for the signal and again for boarding after the intersection.
Today, given a political will for this, trams could reserve a slot before approching the intersection, run through unhindered and only stop for boarding after it.
Only on very busy intersection where the trams' reservations will block each other this could still be an issue.
For the same reason pre-sorting tracks still exist, like in map related for west/northbound. The intersection has priority signal now and there are never two trams waiting next to each other. The track layout will eventually be chanced to only two tracks (but with wider platforms, which would definitely a good thing), but those things take their time.
