I've had the calculations done by the professionals in Europe. Trams are
the winner. Don't forget they have their maximum torque from zero km/h. A
bus doesn't. Watch a few derbies in Europe (legacy systems of course) with
trams accelerating at 1.8 m/s/s, no contest. Even with the Sydney trams,
however, the drivers aren't accelerating to the full potential of the tram
(why should they, when they have to slow down soon afterwards for some
stupid restriction?) so you can't really judge the real potential of the
tram. Some bus drivers are now having a great time with the novelty (to
them) of electric buses which provide a new dimension to the traffic light
derby! That's pretty-much on par with a tram, perhaps even better.
