Hybrid buses in use

There are 225 diesel-electric hybrid buses in London, running on
routes 3, 12, 15, 16, 24, 76, 94, R70, 139, 141, 149, 380, 328, 360,
371, H91, E8, 73, 436 and 188.

The 225 hybrid buses operating in London are split between 7 bus
operating companies and 10 different types of hybrid buses.

Hybrid buses get a big thumbs up from me.

On a related note , what happened to those hydrogen buses that were plying
their trade around central london about 8 years back and that Mayor Ken made
such a big deal about at the time? Were they sold, scrapped, or just left in a
depot to rot?

Presumably they could have been converted back to conventional fuel. We
had some Dennis Darts in Southampton running on hydrogen around the same
time. They disappeared at the same time as their conventional counterparts.

Doubt it, AFAIR they used a fuel cell, not just a piston engine running on
hydrogen.

The original ones are scrapped or stored without running units in
preservation hands, some new ones arrived last year; the first lot
were M-B Citaros, the current ones are VDL/Wrightbus.

If you mean the ones I think you mean, they were running on liquid natural
gas or somesuch. Ruddy great tanks on the roof, made them the nearest you'd
get these days to driving a trolleybus, and the tanks held enough gas for
3/4 of a day's work.

CNG is used to fuel buses in Vevey, CH and also I think in Delhi.

A CNG powered bus was used on the Cambridge City Centre shuttle for several
years. It wasn't reliable enough, though and was replaced by a better Euro
standard diesel.

Just wondering if hybrids, electrically powered, have to be checked
for current leaks, in the way trolleybuses used to be?
Does static electricity build up a charge on them? Or am I way off
course here!
