How can a signal failure on the jubilee line cause so much chaos?? If its
affecting the ATO why can't they just drive the trains manually through the affected section? Or has more than just a signal gone wrong and they don't want to tell us? Plus it would have been nice if LU had listened to what people were saying about using Charing X as a backup terminus instead of just closing the jubilee platforms and walling up the escalators for no good reason. Still , if the powers that be there had brains they wouldn't have been working for LU in the first place I guess... |

No, the Jubilee Line does not use Full ATO, all Trains are driven by

C) A few passengers who get off a charing X? What about the 1000s who go to westminster who instead of just going charing X-westminster on the district had to go via the victoria line to victoria from green park then the district? Sure , its only an extra 10 minutes , but then if you take that attitude why not strip out half the tube lines in central london? Is the tube there for the convenience of passengers or is it just a giant train set for LU to run as easily as possible? Have a long think about that because following your logic the entire circle line (along with a lot of the H&C) could be closed as you can reach all the stations via other lines. And I won't even mention the parallel running on met/jubilee/chiltern , district/piccadilly lines. B2003 |

Keeping Charing Cross for emergencies and special workings was considered, but decided against for several reasons. Charing Cross had quite low passenger numbers on the Jubilee line. The escalators were also pretty much at the end of their working life and so to keep the station open or available on the Jubilee line would have required escalator replacement which is very expensive, especially for a station which would only be used for emergencies. There are escalators still in use which are more than twice the age of the Charing Cross (Jubilee) ones. If they have been used by 'quite low passenger numbers' they might be expected to last longer than most others. Were they under specified for their purpose? Could passengers still be evacuated from a Jubilee train via Charing Cross in the event of a real emergency, say a fire in a tunnel? |

Yes, there is Exits from CharringX, and the platform still exists, so does the Signaling system. The station could not open, but if an emergancy occured, passengers could be evacuated via the station. |
