In prague, the trams all run on time - within 2 minutes or less of the posted time. So I think this article is incorrect for this particular context.

Trams don’t have traffic in the way that buses do, and there are only minor differences in the drivers that could cause anomalies (I.e. you can’t steer a tram the wrong way) so they’re much easier to keep on time.
