Racka- No not 1932 1999 to practically 2010 when it was most reliable apart from signal failures but faulty trains were not as frequent as now

I am rather surprised at the lack of discussion of last night's Jubilee Line catastrophe on the message boards. As a layperson I struggle to understand :
(a) how a tube train can "stall" - if this was the cause of the problem
(b) why the problem cannot be easily resolved
(c) why - according to press reports which I accept may not always be reliable - the driver did not give sufficient information to passengers - surely one of a train operator's main roles in these circumstances is to inform and reassure passengers at regular intervals ?
(d) if the driver was not being told by line controllers what was happening, why this was so ?
(d) what plan is in effect to rescue passengers in these circumstances ?
(e) what are the time limits for initiating a rescue plan ?
(f) why - according to press reports - the plan to push the failed train towards the next station failed because of the tunnel gradient - surely the gradient and likely success of this will be known to line controllers ??
I appreciate that - given the Jubilee Line's appaulling track record - some of these issues may have been debated in the past, so if anyone can point me in the direction of previous threads I would be grateful.
I am not meaning to be unnecessarily critical, just to understand why such a problem cannot be dealt with efficiently.

It's the signalling, isn't it? since some of the equipment is on the trains? so when they say faulty train, maybe its something to do with the train interacting with the signalling equipment rather then the hardware of the train itself

According to TfL's own jubilee line twitter feed there were minor delays occurring (again!!) between Stratford and Canary Wharf due to faulty trains this morning. They really must be having some rather catastrophic problems. Because its a last resort?? I thought after other serious incidents with passengers being held in tunnels in the heat for hours and hours and needing the ambulance service to treat heat exhausted passengers etc., that detrainments now happen after half an hour. |

Too many senior managers involved and counter-manding each other despite Rulebook 2.

And 2500 passengers involved not 800 surely?

Out of interest, what does Rulebook 2 say, in broad terms?

Its funny since TBTC started things have got worse when I used the Jubilee line when it first opened it was so much more reliable then! In 1932?  You see, it's that CTC signalling that no-one liked apart form Morkill. ;D ;D ;D ;D |

Many, many things. Bad seals (though you'd need quite a blowout for it to empty the line), hose/pipe broken... as the top of the list. I recall a story involving a tool left trackside causing a main line burst...
