Of course what's been said about a double frequency bendy bus in place
of a tram, but with all the requisite infrastructure except for tracks,
is precisely what the East London and Greenwich Waterfront Transit
schemes are about.

Furthermore, my understanding is that the schemes are being designed so
that they can be upgraded to trams at any time.

The main difference with where trams are being chosen seems to be where
the predicted volumes of traffic make the environmental benefits of
fewer trams outweigh their increased costs over a very high frequency
of buses.

CRT mentioned 80 (!) trolleybuses per hour over the central section at
peak periods, as opposed to 40 trams.

Um, when I went to a presentation by a man from TfL, it was 110 (!!)
trolleybuses rather than 40 trams. That's just not workable.
