Perhaps they can for a short stretch of track, but I don't think
that I've ever seen anything close to this on the whole length of
a single line. Anything more than one tram about every 2 minutes
causes bunching at traffic lights [1] and stops.


The Cross River Transit tramway plans for a 90-second headway through
the central section. On most modern tram systems, the approach of a tram
will clear traffic lights in its favour, so these rarely cause delays -
stops do, of course.

Indeed - priority should be given to CRT throughout its whole route,
with the exception of the crossing of the Euston Road. The 90-second
frequency is the limit not for any spacing-related reason but because
firstly, this is the required timing for a light sequence at the Euston
Road/Eversholt Street junction to stop traffic locking up on the inner
ring road, and secondly to prevent excessive delay to the high number of
bus services crossing the route at the Strand and Holborn.
