The reason the 3rd platform at Stanmore is not being commissioned until the new signaling is ready, is that it would be a waste of time and money to install signals which would have to be ripped out in 2 years time.

I think you miss understand me.
I am commenting on the construction and not on the commissioning of the 3rd platform.
The construction has been going on for far longer than constructing a 30 story building in canary wharf, for example. Where huge foundations had to be built.
This is also on par with the new ticket hall in elephant and castle. Where again parts of canary wharf were built in third of the time of a tiny ticket hall.
Understanding the full extent of these projects, the construction of the third platform as with other LUL projects are much longer than similar projects of this size outside of LUL

Off topic, but the longest job must go to the dripping tap at Bounds Green - 8 months before they fixed it, and now the tap has been removed altogether!

The immediate risks I can see on that particular site is the proximity of the worksite to the track. What if the embankment slipped and shifted the track? Likewise vibration from piling work? The ground might give way under the concrete truck outriggers at the top of the bank and topple over. The bucket of an excavator may turn and strike a train or take out a load of lineside services etc. I'm sure Tubelines have measures to keep the risk of these occurences low but they are risks all the same.
It's all very well building something new in an open field with unfettered access. LU still have an operational railway to be run in a safe manner with the minimum of closures.
It would be easier to demolish an entire station and rebuild. Many of these structures are over 100 years old with unknown condition internally possibly full all sorts of contaminants like asbestos and with service cables all over the place. Try dealing with that in a section 12 station. Many are situated in built up residential areas where noise and access is a problem too.
Fragmentation of the system has not helped. Imagine trying organise a weekend possession and coordinating this with the local authorities to close the public road so you can locate your mobile crane. Then hope that there is enough technical officer cover available to disconnect and reconnect signal cables before and after work.

The primary elements of the platform structure now looks complete along with a the shells of a couple of platform buildings. One even looks like the shape of an SSO.
The ballast and drainage has been laid and looks ready for the platform track.

Thanks for the update. I know I've probably asked this before, but does anyone know what the new track layout will be like (will it be Stratford/Morden style, Uxbridge style, or completely different)?

Concrete track sleepers have now been laid on the first 20m of the north end.

The sleepers have been laid for most of the platform now.
It appears that the signal controlling the junction to the existing platforms is being relocated (or being kept until a new one for all 3 roads is commissioned) and there's also a new concrete base constructed a few metres south.

Noticed that the sleepers had been laid on Saturday. I notice that there is a gap between the platform and the retainging wall. I presume this will be infilled and used for the buildings that may appear on the platform, such as a waiting area?

Couldn't say but they may want access for maintenance of services at the back. There was a poster with an architect's impression but it got removed. There was quite a prominent platform canopy I recall.

The service suspension this weekend 22nd/23rd is to install some of the pointwork for the 3rd platform.

And when is it planned to become operational? ;D There are more Wembley-Stanmore closures later on in the year. Assuming that they are also for the 3rd platform, then I don't think it will be operational until late '06, or early '07. When you made this post in May last year, did you realise how optimistic you were being?  ;D |

As I have said elsewhere in the Jubilee Line area, Baker Street SCC will never (or are unlikely should I say, U-turns are not uncommon) control the new platform, as it is too costly to re-signal, commission, then re-signal again once the area is transferred.
This puts a date of at least 2009 if not 2010 or 2011 for the platform to be used.
I did mention the phrase "white elephant" earlier in the thread.
Of course, now that the new pointwork is shortly to be installed, and proving for the points enabled, and as the points will not be left secured for current running, we will soon have to take account of their existence when failures occur in that area. Therefore, a set of points neither Jubilee control room has control over will soon be able to shut the railway down.
