I noticed Mark that you put a comment in the Guardian about the effect of
fixed truck trams. While this is certainly relevant on s system with lots
of corners and curves, it's not such an issue on straight-line systems.
Their lethargic performance in cities like Sydney is not just down to fixed
trucks, as a ride on a Skoda 14T will demonstrate! More significant is
having all wheels powered and the driving style. Am I correct in saying
that the only trams with all wheels powered in Australia today are the
Melbourne Zs and As?
