Considering the Central Line was refurbished in the 1990s, why is there a part closure today?

Engineering works happen for various reasons and 'ugprading the victorian network' is a very bad excuse! As for what is actually occuring, one does not know. I don't think however that all track was replaced with the central line upgrade, and in places, you can bloody well tell it! |

The entire West Ruislip branch has been replaced with flat bottom rail, the last section I think were the platforms at Northolt

Rail and points replacement at White City. And probably a little tinkering elsewhere.

A criticism leveled on LU is that they don't inform the public what actually is happening during engineering weekends. So LU introduced the "Tube Upgrade Plan" which replaces the "TfL investment programme". Apart from the name change, the general managers of the lines are supposed to post a you-tube clip on the TfL website giving details of the work being undertaken. Peter Tollington can be found at www.youtube.com/user/TransportforLondon#p/u/6/n-qC1ZVzWio explaining this weekends engineering works. |

Track replacement. Before this weekend they recently replaced Points and Tracks on the Eastbound on the approach to Bethnal green.
When the Central Line was upgraded, it got new tracks only on the long open sections. Combined with the 62mph max speed the 92ts delivers (or used to deliver), this is where time was expected to be recovered and provide the 36tph service. 36tph was quickly re-written down to 33tph by signalling limitations and now it only does 30tph due to lack of Power from the Substations which are overworked.

They could have at least filmed the right sets of points, the ones featured were replaced in 2007! |

I was told by Peter T on VT2 a year or so ago - ( so don't blame me if this is *entirely wrong* ) that during the peak the Central's east end power supply is supplemented/boosted from the District. If that's the case then when the District gets it's power sucking S stock it might want to keep it's leccy for itself.

Nice. Overrunning engineering work and two signal failures!

The entire West Ruislip branch has been replaced with flat bottom rail, the last section I think were the platforms at Northolt Rail and points replacement at White City. And probably a little tinkering elsewhere. Complete replacement of the four diamonds and all associated points trackwork at the west end of White City by flat bottom rail. I understand the job was planned a while back as routine maintenance but overall cheaper to do a complete renewal. Line has a special SX WTT on the control system this week, next week and week after because of these works, as well as different weekends specials across all 4 weekends (i.e. incl before and after). I didn't look in detail as its outside my remit as I'm an engineer not an operator - but AIUI the SX specials are to do with certain moves not possible at WHC during the works period, I don't think there is a public service impact anywhere. Don't forget the Central has generally been keeping going during the period of Jubilee TBTC works south/east of Baker Street. Now thats gone TBTC, the Central has to get its turn at maintenance. Since TBTC Jubilee started I've had Central control system timetable CDs appearing like confetti to deal with. -- Nick |

If that's the case then when the District gets it's power sucking S stock it might want to keep it's leccy for itself. Which always brings me back to something I suggested ages ago in that why don't LU build an off shore wind farm, and go back to generating their own electricity? Ok, so the initial outlay is vast, but then sit back, reap the rewards, and even sell the spare on to the grid. Far better chance of running nearer a profit (I dread to think how much they cough up for electricity a year) and issues such as the above quote will be avoided altogether. |

Well, they DID own not one, but TWO power stations at one time. One was in the Greenwich area (now demolished?), the other, Lots Road, in Chelsea,is still extant. As far as I know it hasn't been converted into and art gallery or something equally chic and pointless, so perhaps now would be a good time to reinstate it and SAVE some money by bringing the power generation for LU back in house? |

The problem with doing things in house is that it looks bad on the balance sheet to the bean-counters. Apparently it's far better to outsource - even if that costs more money!?

30tph? That is only managed for 1 hour in the morning peak on the westbound!!! Still waiting for 30tph from 4pm - 7pm in both directions, which I was informed would be happening by 2012. Seeing is believing! I think it is stunning that the line actually provides a lower frequency that what it did before they spent £750 million on it . . .

Greenwich power station is still there - photographed it last year.

I actually thought there were a couple on the North Bank as well  Oh well, it matters not - They shot themselves in the foot by outsourcing it in the first place, but more so now with the economic climate, and the opportunity of free electricity from wind farms. Still, we're drifting OT... |

When someone posted a link to contemporary news film (from 1947?) regarding the Central Extensions I'm sure it was talking about 40 tph... |
