I noticed that this morning on my way though. Ok, I wil admit this is a stupid question (and I havent yet had time to watch the stomo  video) but is it moving or bits added on the southern end? Logic tells me the latter given the sheer mass of it!

Most definitely a 'bridge slide'.  The mechanics of how it all works (strand jacking) were described in detail in post #681 in this thread, back on page 46...

Thanks Paul...must make time to read this in more detail (not easy on a mobile!) but IMHO it is certainly an impressive operation!

It moved again last night. The south end of the transfer deck is now centred over the supports on platforms 8/9. Is this as far as it will go for a while?

The post I just referred back to confirms that it will be held above P8/P9 for a while, the initial move was explained to be 28.5 metres.  The gap between the P8/P9 piers and the P7 abutment is rather longer than the distance they've just covered, so I assume they need more weight on the north end now to balance that out.

In fact, having now looked at the webcam pictures, I'd estimate that the next gap is a bit longer than half the length of the existing structure - so it will have to be made longer for the procedure to work again, IYSWIM...

I think this could also be done by adding significantly more temporary weight to the north end as a counterbalance, but it probably makes much more sense to spend a little more time adding the normal structural steel, as that only has to be done once.

BBC showed a video report of the bridge being moved yesterday. An NR spokesman said that the new footbridge would be completed earlier than planned as things had been progressing so well.

BBC internet report:

http://www.bbc.co.uk/news/uk-england-berkshire-18762712

"Work on Reading rail bridge is completed"

Er, don't they understand about phases of work?  If a BBC reporter had actually visited the site would he really write that?

Paul

PS Had reported my criticism last night via BBC website comments page - and give them their due thay have amended the article slightly to refer to a 'section'.

Meanwhile Platform 6 is nearing completion and is scheduled to open on Thursday 12th July, when platform 5 will also be open along its full 12-car length of 268 metres.  So that'll be 3 12-car length platforms (for 20 metre carriages) with 3rd rail and permissive working to increase operational flexibility in time for the Olympics.

That will be very welcome news to me! Hopefully when my homeward bound service pulls in a P4/P5 the "human" congestion will be alot less!

Does that mean that the tubular steel fencing bolted down along P5 (beyond the 8 car length) has only been temporary during the works?
