I presume the driving was 100% manual (in the tunnels) then?
I have to say I was very impressed with the driving then! It was so similar to ATO and some excellent braking and judgement going into stations, just about as good as the ATO itself! I noticed subtle differences but they were so subtle I wasn't sure!
(If only t/ops on the rest of the network can imitate your braking, we'd be saving 5 seconds of journey time per station!)

It's near impossible to totally replicate ATO mode while in Manual... theres no way a human can practically 'push the limits' in the same way the ATO can... I've known ATO to make a boo boo once... And 'not again' me thinks.

we were indeed in CM... hopefully, all should be sorted tomorrow.... The actual bill is making its way to relevant party; It's only £850,000... If that's the case, why was I on WB 203 this evening that suffered an ATO stop short at Perivale WB? |

Am I the only one who wants to know why a timetable changeover was attempted DURING THE WEEK?!?
Surely it would have made more sense to try it on a Sunday morning, so that in case this very problem happens, Metronet doesn't have to deal with a totally b******d morning peak!

I would suspect that any control problems at Wood Lane would definitely necessitate Coded Manual. Why? All the functions required for ATO are local. |

I never knew that; I always thought ATO was coordinated from the center. Still, considering the massive problems that the line was experiencing I guess Phil and his buddies were the ones who decided on CM. |

Although operation was certainly a lot better than yesterday something else was completely b****red today. The indicators kept saying 'next train in 1 min.' which lasted for at least 8 min.  The train after that would jump from 19 to 7 to 13 to 19 again, all within ten seconds. The system completely lost any idea of actual train whereabouts so it seems. |

I don't know any of the details but if the Central Line system is anything like that at Baker Street then as far as the computer system is concerned then the Monday to Friday Service is a different timetable to the Saturday and Sunday services even if they appear in the same Working Timetable. There can only be one active timetable on any one dayand on a Sunday it must be the Sunday service and so if there is a problem with a new timetable that only affects the Monday to Friday service then it will only come to light on the Monday morning when it is first used. This totally ignores any procedures that are in place that should check the timetables before they are loaded for any errors |

news.bbc.co.uk/1/hi/england/london/6169570.stmApparently, Metronet could be fined for over £1M just for the Central Line case while the Circle etc. engineering overrun would only be £100.000. I guess overruns may be valued differently because 'they can always happen' while perhaps errors like the Central Line could have been prevented. Best way to prevent a thing like this would seem to be an extra computer standby with a standard timetable as a fallback. A 'simple' timetable utilising 75% of the trains and headways of 5 min. instead of the usual 100% and 2 min. would have meant a considerably smaller disruption. The fines that the infraco's have to pay is based on a formula called "lost customer hours" (amongst other things). Basically the number of customers and the length of the delay (and consequential delays). Over-running engineering is often cheaper than re-booking the possession and paying staff etc. One little fact that for some reason sticks in the mind, a 3 min delay on a N/B train at Tooting Broadway costs just under £3k. |

A grand a minute! ;D
Metronet really have to deliver consistently over the next couple of years, and try and win some support from both TFL and the long suffering public.
Going slightly off topic, the substandard have loved this story.
It is only fit for polishing shoes, that rag.

BUMP.
I see that the Central is still struggling along with a "signalling systems failure" - are the computers at Wood Lane really that badly knackered?

At a guess I would say that the computers at Wood Lane are still using the old timetable however, the drivers duties are on the new timetable.
Therefore delays and cancellations will happen because drivers and trains are in the wrong places at the wrong times.

The delays have gone from 'severe' to 'minor' and I must say, as an ordinary user you hardly notice these minor delays. Monday was a disaster but after Monday, the headways got more or less back to normal. For most passengers it doesn't really matter if train x is at station y 15 minutes later than it was supposed to be, as long as there is a train very few minutes.

Due to the problems - they made one error by running shuttle services from Leytonstone-Epping & North Acton - West Ruislip. This caused more overcrowding in the city in the rush-hour. I did notice the next day -they were running a through service that eased of the crowded platforms.

Could they not have some BTP people at the location or set up a remote video cam?

BUMP. I see that the Central is still struggling along with a "signalling systems failure" - are the computers at Wood Lane really that badly knackered? They got WTT 64 loaded on Thursday. But I would have thought there was a back-up control system at Wood Lane. Surely there is a duplicate computer for training and standby and it is swapped with the operational computer from time to time to practice for occasions like last Monday morning? Can anyone tell us what the set-up is there? |

The train after that would jump from 19 to 7 to 13 to 19 again, all within ten seconds.
