Re: Brisbane Busway

[JJJim <jjjim@bigpond.com>]

A bus weighs about 10 tonne empty up to 15 max wen full.

Light rail carriages are about the same or slightly more each ,im pretty sure. but theres more than one carriage and may be up to 3 fitting in a span between supports  (elevated sections of course). also
add the track as u mentioned, and the higher impact / vibration .

as for efficiency . the electric motors are much more efficient than the Deisel in a bus. espcially with the automatic transmissions being very lossy in busses.
