Hi,
Regarding the new Vastern Road bridge I am intrigued to see that the bridge extension is using the same design. I take it that all the original design plans were available for new parts to be replicated or did carrying on the same design involve investigating how the old design was done?
I'd assumed that the widening would just involve two new bridges (with a different design) either side. What they're doing is much more impressive!
Cheers,
Boppy.

Nuttalls built the existing bridge when the road was widened in the seventies - they should have kept the plans, but if they hadn't, NR» would have done. Matching existing was a planning requirement: http://www.bamnuttall.co.uk/PDFfiles/ReadingStationRedevelopment.pdfPaul |

Thanks, Paul. I only noticed today that the bridge supports across the Vastern Road had started to be installed.

The Platforms get renumbered this Xmas, together with some signalling & bridge work - and one additional platform, I understand.
A 5-day Oxford - Didcot blockade is also being scheduled this Xmas (possibly for other work)
Then Easter 2013 is the next major blockade.

Do you know what scale of disruption this will cause to services through reading, and any idea whats being done? |

Had a look at the exhibition this morning - it gives little or no new information really.
The key point I took away is that the newly compressed timescale (saving a year) is mainly to do with the western grade separated junctions. There is little or no change to the previously published timeline for the station works - it may complete a couple of months earlier, but not much.
Regarding the Southern (Waterloo) platforms, the plan is that in Jan 2012 they'll start using the new platform (P4 in the renumbered scheme), and the existing pair (future 5 and 6) will then be taken out of use one at a time and lengthened and straightened, by summer 2012. The new track layout, ie the two track approach and various crossovers, will be complete in Jan 2012 though - which will overcome the limitation of the current single track over the bridge. New info (at least for me) was confirmation that the three platforms will be dead straight and parallel - ie the current curvature to tuck in behind P4 will be removed.
(Recent PR▸ seemed to suggest this area would all be finished next Jan, but this seems to have been an oversimplification.)
The key date of Easter 2013 is when the four new relief line platforms will be brought intom use with a big bang, having been built in green zone conditions, ie outside the blue fencing which denotes the operational railway boundary.
The following info, mostly discussed before was reconfirmed:
Current P7 bay will close this December, as the space is needed for the new transfer deck.
Current P5 and P8, the down main island, retains its current shape, but all the buildings will be removed - this will be done behind hoardings with the platform faces remaining in use.
Current P4 will be closed some time (late in the sequence) to be straightened somewhat, the middle of the platform will be extended out by a couple of metres as there will only be two tracks rather than the three current.
Current P9 will be extended southwards over approximately one track width, to widen what will be the up main island, and the P10 bay will be filled in. The buildings will all be demolished, again this will be done behind hoardings with the platform in use.

Thanks, Paul. That all pretty much makes sense. Do you know when the southern underpass at the eastern end is scheduled to open?

Are any of the on platform buildings being retained or replaced? Or will we go back to buying food and drinks on trains again?
