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.

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!

They don't need to be checked for leakage current every day, no,
although the systems on ours are self checking for other safety risks.

Having ridden on most of those routes, I think it's only on the 12 (and
possibly the 38 NB4Ls), where the vehicle shuts off the diesel engine,
then runs on electricity only as it accelerates for a few metres from a
stand, maybe to 10mph, then the engine restarts and takes over for
normal running.

I was on one of the new hybrid buses on route 12, the ones where the
internal combustion engine shuts down at bus stops and/or traffic signals.

I think the NB4L vehicles on the 38 also did this, but the ambient noise
(the bus' a/c???) was quite loud, so I couldn't tell for sure.

Are these two routes the only ones that run like this?

21, 141 and 76 also run with hybrids, IIRC.

The TfL 21 does not use hybrids.

Indeed.

One of them crashed in Lakehurst, NJ and Ken gave up on them.
