Wow!!! My local garage as well. I think some of those buses are completely finished now. Also I'm shocked that one of the electrics started it. What is so surprising? Is it because it's a new bus? No. The fact it's zero emission and still caused a fire. Apparently it was the chargers that caused it.

What has a bus being zero emission got to do with it? You really shouldn't post things as fact especially as they is likely to the fire brigade investigation going on.

Where the bus is parked, there is no chargers there to my knowledge? Last time I was at Potters Bar was just before the pandemic and I don't remember any chargers at that part of the yard. The charger for the sole Metrocity is located inside whilst the other chargers should be in the forecourt to my knowledge but as your local, free feel to correct me As others have said, too early to say what it is.

Anything that is a conductor of heat can cause fire... even a turd. Aluminium is fuel for fire. The fact that it is Zero Emissions has not got anything to do with it and does not mean they are fire proof. As has already been stated no one has been hurt or injured that is all that matters, the pieces of metal destroyed today who cares new ones can be built.

So if it was a diesel that randomly combusted it would have been fine? Whatever seems to have happened today shouldn't have happened to any bus at all and will warrant an investigation.

As has already been stated no one has been hurt or injured that is all that matters, the pieces of metal destroyed today who cares new ones can be built. Melting Aluminium is very dangerous, if water gets into contact it can explode. 660c and the water becomes superheated steam, the steam causes minute pellets of aluminium oxide to be ejected, and an exothermic reaction occurs releasing hydrogen, which combines with oxygen to burn very fast It is a problem for most local fire engines as they are normally water pumps and rescue vehicles, and unable to spray fire retardant foam, unlike say an airport fire truck. Spraying water on burning aluminium just rapidly intensifies the fire and usually results in an explosion.

And modern batteries burn well in excess of this temperature, meaning they melt the bus as they burn.

And modern batteries burn well in excess of this temperature, meaning they melt the bus as they burn. Firstly and foremost I am extremely saddened to hear about this fire, at least there seems to be a silver lining that no one has been hurt. Unfortunately no type of bus is exempt from catching fire. Remember the Routemasters, bendy buses catching fire, the list goes on. Batteries in electric buses can catch fire if they overheat. Electric cars are no different. Much goes into ensuring the batteries do not overheat, particularly when fast charging. Things can go wrong, there can also be manufacturing defects in the batteries themselves. I am not going to try and second guess what happened here, I'll let the official investigation determine that. Hopefully not too much damage to the garage itself and hopefully PB can provide a full service tomorrow, perhaps with some assistance from another garage (HT comes to mind).

The fire brigade has confirmed it's six buses - judging from everyone's reports here, it's two VW's, two OME's & two Enviro 400's. As others have said, what's more important is thankfully no person has been hurt by this incident

Temporary withdrawal at other companies with MetroDecker EVs as a precaution

AC already helping out with VWH2321. Speaking of which, I noticed two Gemini 3 B5LHs deadrunning last night into Golders Green, as if transferring, one of them blinded for 6. Was very odd at the time and couldn't figure why (didn't hear news until I came home).
While sad to hear of 6 buses destroyed esp an ex First VW, also glad to hear no one hurt.

TfL instantly removes 90 London buses from service after huge fire that saw 6 buses engulfed in flamesThe electric bus model is being kept off the streets after one suddenly became alight in what could be an issue with the batterywww.mylondon.news/lifestyle/travel/tfl-instantly-removes-108-london-24033800The routes being disrupted are:
