The only thing that is "fundamentally wrong" is the large number of flat junctions on the SSLs.

You'd think the BBC of all people would notice the absence of Wood Lane. BBC London is based in the Egton wing of BH, not with rest of television news at TVC. Anyone needed to travel between the newsrooms would get the shuttle bus, or the Central Line. The Central Line links together Bush House, Broadcasting House, and Television Centre. That's the whole spectrum of multiplatform local, national and international news from the beeb. So if you want to make the largest number of journalists grumpy, delays on the Central Line is the way to go  BBC Journalists can also use Wood Lane to Great Portland Street on the Circle/H&C, yet it's not as straight forward as the Central line obviously. |

They can but they won't > > > they use taxis.

Ridiculous considering the normal journey from White City to Oxford Circus can be quicker than a taxi. Incidentally, I've worked in the White City area and have seen plenty of BBC badged staffers (probably Admin) using the Central line. Can't comment on the H&C/Circle though. |

The only thing that is "fundamentally wrong" is the large number of flat junctions on the SSLs. There is nothing whatsoever wrong with the junctions - provided they are used in a realistic manner. The timetables we currently have on the SSR do this. There have been timetables before now which didn't - but that wasn't so much the fault of the timetable itself, but more a fault of those who wanted to squeeze the last drop of line capacity out of the system. |

^^Well passenger numbers on the tube is going up and more capacity will be needed. I don't see how you can claim that flat junctions are a good solution on an overcrowded metro system...

I don't think anyone would claim flat junctions are a 'solution' The solution is flying junctions at all locations, but unless bank of Edwin is going to pay for them, then flat junctions it is ! They just need to be used in an appropriate manner and in the world of increasing passenger numbers that is the challenge ahead for LUL planners and operational staff |

There is a very well known saying that "less is more."
In the case of providing a reliable service to move larger numbers of people through London, the solution is not always to shove as many trains as possible down the hole.
A regular, reliable service will tend to do more than a hap-hazard unrealistic bunch of trains, which could come to a grinding halt at any moment.
There is no plan, no money and very little space even if we had the money to redesign any of our flat junctions into flying junctions. We're stuck with what we've got, and with careful and professional operation, we'll keep things moving.

Now this stretch has re-opened, does anyone have a summary of what was achieved & news on whether everything went to plan?

Now this stretch has re-opened, does anyone have a summary of what was achieved & news on whether everything went to plan? Going up & down today i couldn't notice anything different between High Street Kensington & Notting Hill Gate, except perhaps some new ballast covering drain works. Between (west of) Notting Hill Gate and (west of) Paddington new flat-bottomed track and concrete sleepers, both roads. Existing current rails have been re-laid. No platform alterations appear to have happened. |

Circle and District line works completed on schedule after four-week upgrade closure
24 August 2011
Thousands of metres of new track and drainage laid in four-week closure. Platform lengthening and signal renewals carried out.
Normal services are operating across the District and Circle lines this morning following the successful completion of four weeks of upgrade works between High Street Kensington and Edgware Road.
The block closure from 23 July to 23 August between the two stations, one of the oldest sections of the Tube network, has enabled key upgrade works to take place.
The works have improved track and equipment and will improve reliability, and have been completed in four weeks rather than six months of weekend works.
This includes work to accommodate the new Hammersmith & City and Circle line air-conditioned trains including power upgrade on the tracks, signal renewals and lengthening platforms.
Track and drainage renewals will also help to protect track circuits from flooding thereby helping to cut down on the number of signal failures.
Two thousand metres of new drainage has been laid down to replace an old system from the 1850s while approximately 3.5km of track from the 1940s has been replaced.
This has involved around 7.5km of new rail.
Specially adapted engineering trains were used to make nearly 400 trips to bring old earth out and bring equipment and new materials in including:
Bulldozers and cranes which were used to remove 16,000 tonnes of spoil in order to take the track down to its base level
A total of 25,000 tonnes of sand and new stone ballast

Not noticed a signal failure in that stretch since reopening. So far so good.

Ridiculous considering the normal journey from White City to Oxford Circus can be quicker than a taxi. Unfortunately, it's also an unpleasant sweaty cauldron. Assuming the taxi fares are on the firm, I can totally understand them wishing to remain above ground!  |

There was an immense amount of work carried out, and completed on time - and given the extra work found needing to be done, those involved should be congratulated on getting it finished within the original timescale.
At one stage, the discovery of over 600 disused drains (connected to properties along the route) was threatening the whole program, and at one stage the work was going to be cut. But efforts were concentrated and the work was all carried out.
As in many things of this kind, the results won't always be visible, and time will tell if the work improves the area.

Was it the bit south of HSK that had similar works plus tunnel strengthening about 10-15 years ago now?

Indeed both sides of the "triangle" had track replacement and (more importantly for each project) tunnel/roof strengthening works. Both were known as the "Covered Way" project. Someone will be along shortly to quote dates |

I took a train from Edgware Rd to Westminster yesterday, and the track on the refurbished section was very smooth - a lot better than I remember from previously. So there are parts of the change that can be noticed by passengers.

1850s? As the quote refers to the drainage system, it's not unreasonable to assume 1850's is correct. |

Jackson's London's Metropolitan Railway, construction of the original Metropolitan Railway to Praed Street station began in 1860, and Praed Street to South Kensington was authorised in July 1864. |

Thanks MC! Can remember the tube maps made with the green and yellow biros on them with the intermittant ink, thought it was something round there.

Do we know if this still (hopefully) took place? I believe it didn't. Whilst originally installed to mitigate some of the track circuit shunting issues caused by the poor drainage, it also had the effect of improving the protection of trains berthed at signals. There is AIUI now some debate and risk assessment as to the pros and cons of removing the sequential signalling. |

Yep, the exact section of track that desperately needed to be replaced...wasn't.
