snoggle they actually made plants grow inside a bus!  Howard Marks would have loved that!  |

snoggle they actually made plants grow inside a bus! Ta for the twitter photo link. Won't be wasting my time to go and see that in Ilford. Or Bexleyheath though they decided to split Bexley & Heath up into two separate words lol. |

Does anyone know what the electric motor power of the E400H is, I know the Engine power is 210bhp but that acts as a generator anyway to recharge the batteries and now ultra capacitors. I believe it is somewhere in the region of 260-280bhp and on the ADL site it isn't exactly clear as there are many figures listed below.
Hybrid Driveline
BAE Systems HybriDrive hybrid driveline incorporating:
140 kW continuous power @ 200 rpm compact water cooled permanent
magnet generator.
195 kW peak power @ 500-2000 rpm.
120 kW continuous power @ 650-2485 rpm compact oil to water
cooled motor with 5100 Nm peak torque @ 0-3200 rpm.
3800 Nm continuous torque @ 0-450 rpm.
360 kW water cooled integrated propulsion control system customised
for optimum fuel consumption, performance and emissions.

Electric motors can produce lots of power for short periods (really a question of how hot you want them to become), which is why the peak rating is higher than continuous rating. 195KW is 261 hp ( or 265 metric hp) The others are not relevant for power to wheels (unless the diesel can also supply power to wheels at same time) The last item rather looks like it will be in generator mode when coasting or braking to minimise diesel fuel usage |

The electric motor size is dependant upon weight / size of bus. In the case of out London buses using BAE Hybridrive I believe the ratings of the electric traction motor are :-
Power peak = 260 hp intermittent = 228 hp continuous = 161 hp
Torque peak = 2100 nm intermittent = 1500 nm continuous = 1000 nm
Electric motors are quite different to diesels. Maximum torque will be produced pretty much standstill (electric motors don't need to idle) unlike a diesel, while power will be available pretty much throughout all rpm.
Hope this helps.

busoccultation was at the event Got tol love how they managed to grow all those plants inside in just under 3 days I wonder how long it would have to stay off road to get a thorough clean?

Yeah I was there for about 30 minutes in Ilford earlier and seeing that I wasn't doing anything at home thought why not pop down to Ilford to see it  Also, loads of positive comments from the public about the work done to put the plants on this bus , plus there is chance to see the bus tomorrow at Regent Street if anyone haven't seen already  |

Looks like good weather for the Essex Bus Rally/The Londoner In The Country tomorrow.
Interesting assortment of new and old buses in attendance.

Are there any buses still in London that use a manual gearbox or is every single bus automatic?

Are there any buses still in London that use a manual gearbox or is every single bus automatic? I am sure someone will tell us about one, but I reckon there may well be none even retired (save for museums), and I am pretty sure none in active service. Even in the days of the RT, prior to the Routemaster there was pre-select, whereby you used a knob to select the next gear and then pressed a button to have it activated. I suppose you could argue that was a kind of manual gearbox, in that the driver chosen the gear, but it was automatic in the sense there was no conventional clutch to operate.
I do have vague memories of the early C11s (and perhaps dial-a-ride the predecessor to the H2), both being very small SDs having manual gearboxes, but I am not sure any examples still exist, but happy to be proved wrong.

Was on the 189 yesterday (Saturday) heading towards Oxford Street. When we reached the junction of St Johns Wood Road, there was a big traffic jam ahead, clearly something was up as the 13, 113 and 274 were all diverted southbound down Lisson Grove. To help 'speed up the journey' as the traffic ahead would delay us, the bus was held at the next stop 'to regulate the service'.  This enabled a green line coach to overtake us. When we eventually got going again, our driver missed the diversion to keep going ahead and turned off down Rossmore Road on the usual line of route, only find he could not turn right at the bottom onto Park Road / Baker Street, as road was closed for re-surfacing. This meant he had to go around the whole block again!  At this point we got off the bus and walked the rest of the way, at least it was nice weather! When we reached the Marylebone Road we could see the green line coach that overtook us queuing to turn right into Baker Street. Good decision to get out and walk!

For me a manual gearbox means a gearlever and clutch connected to a manual gearbox. The RM I think was first bus to have a proper automatic gearbox, one of its ground breaking features at the time I believe. Yes, you could bypass automatic mode and select the gear you wanted using a knob, the auto box would select it but there was no manual clutch, it was all done by the box. For this reason I don't consider the RM (15H) as having a manual gearbox. |
