- Greenwich Waterfront line - interesting!

Not so much a railway or tram as a "super-bus". Segregated alignments
initially for bendy-buses, with allowance for later conversion to tram.


Trolleybuses, not just bendy-buses.

TfL view this as a "transit" network - superior to buses and almost as
good as tram


"Rapid Transit on Rubber Tyres" was the term being used at one point.
The separate alignment, fixed infrastructure - overhead wires - and
special vehicles were all designed to make it look more like tram/rail
and less like bus.

The same is true for East London Transit.

GWT will use diesel buses.

ELT could be either diesel or trolley but they haven't released as
detailed a plan as for GWT yet.

I never understood the point of trolleybuses. If you're going to have fixed
electric infrastructure why not have a tram and get the extra people carrying
capacity and greater efficiency. Whats the point of a bus if its physically
limited to fixed routes?

It's cheaper to install from scratch, because you don't have to dig up
the road to lay rails, divert pipes, sewers, wires, and so on.

And it's cheaper to maintain, because someone else pays to repair your
"track".

There are disadvantages - lower capacity and lower efficiency - but on a
medium-load corridor these might not be enough to matter.

Abroad it has survived in some places due to certain conditions

In some places it has even been resurrected.
