Hi
Severe delays this morning due to lack of trains. Where did they go to? Or where they too cold to start after the cold snap overnight? They're cold at the best of times so I wouldn't be surprised...
Thanks

Ok, I'll admit it, it was I.
I have kidnapped seven of them and taken them with me on my #GrandUKtour (all line rover). Whilst initially I planned to put them to work on the Fife circle, it turns out the Forth Bridge couldn't take the weight should two crush-loaded sets pass each other; I'm currently heading south with them. The plan is to load them into the hovercraft at Southsea and exchange them for the 38ts so that commuters on the mainland can finally enjoy proper trains on their commutes.

Most helpful everyone. Thank you all very much. BTW did I post in the correct forum? This is the Jubilee Line one isn't it?

I wonder in the meantime if there is some sensible information from the more "normal" members out there  |

Can we keep the comments civil please. Maybe no one has answered the question because they don't know the answer. If any further posts do not include the answer this thread will be locked and sent to post heaven/hell

Depot problem at Neasden, it appears.
But no further detail about what the problem was.

A certain amount of informed speculation here, however putting two and two together it appears juice was off in Neasden Depot over the weekend, and when the trains were powered back up they succumbed to various defects. Trains don't like being cold started in cold weather when they've been stabled off current, with no heating running etc, especially if it's been for a longer period. |

17 trains unable to start apparently. Let's hope they put some good plans in place to avoid a repeat next week!

Does anyone know why the trains won't start?
Motor problems cause by thickened/set lubrication?
Electronic/electric problems?
Brake problems? (using start in a more general sense
At least they won't have steering problems (unless you count stuck points).

(using start in a more general sense Not sure in this specific case but if train batteries/power packs are drained below a certain level, as traction power has been off for a long period (weekend engineering) etc then the contactors to auxiliary circuits, MG/MA Motor Generators/Alternators, ACM Auxiliary Convertor Module and compressors would drop out of circuit. These can only be 'set' by battery power, which the train doesn't have; even when the traction current is restored. (MG/MAs provide trickle charge to batteries/power packs) |

We had problems with some of them on Sunday morning unable to pass a brake test after they were sat in Stanmore siding in the cold overnight
A colleague had two trains fail on him before a third one passed. To make matters worse, the points failed as he was about to come into the platform.
No wonder there were problems at Neasden

(using start in a more general sense At least they won't have steering problems (unless you count stuck points). It's not just the train failing to power up or pass the brake test, but the train is also more likely to pick up defects which mean it cannot be offered for service, or which in service would require it to be withdrawn from service. Even a bit of damp in wiring can cause things to happen. |

It would but depending on time available to prep trains, after the juice was restored, there may not have have been time to do many fixes before start of traffic, and if problems were ice related probably very difficult to sort until the day warms up. |

The traction current would of been on all night and if a possession was planned for that night then the trains would of been prepped before the authority would of been given to take the possession
