Getting back to the matter in hand - the very large crane has turned up again this afternoon with all the extension pieces. Any idea what it is going to do this time?
Its in the same place as last week so looks to be something on the London side.

I am sure I have a photo somewhere but I think the signal at the London end of platform 7 has a theatre box rather than feather(s).
Correct. Signal R49 (now TR49) was commissioned in November 1979. Platform No.7 (previously Platform No.4) was only reversibily signalled from that date. From the commissioning of Reading panel on 24-26 April 1965 until November 1979 there was a shunt signal R563 at this position. The current signal has a Route Indicator for the Up Main or Reading Spur lines. In five weeks time it is being replaced by new signal T1682 temporarily on the new signal gantry that can be seen here (its on this temporary post as it will be replaced with a proper caged signal in a new position once Platform No.7 is rebuilt against the present Up Main line): http://www.flickr.com/photos/mark_iliff/8416219893/in/pool-1945836@N21/lightbox/ |

Thanks for that info, I was guessing that that signal was in a temporary position in a discussion with 'GBTE' back in November, around post# 927!

It may be the removal of the footbridge to the carpark. The Network Rail announcement in December said that the footbridge would be removed by the end of February and they have almost finished the tunnel under the station - probably a day's worth of work left. |

Ah ha ... Large bits of metal have appeared. How about the canopy on the London end of platforms 10/11

Seen this morning:
Tilehust East junction is being relaid. Up and down relief lines being relaid to connect to new lines/freight line with what looked like connection for fast line - although these were not being connected.
Track over Cow Lane bridge has been relaid - but not yet reballested.
Additional signalling/RA indicators being fixed in situ along P12/13.
Channel being dug under country end of P8/9 and relief lines - but not obvious what the purpose was for.
Could not see what the large mobile crane was lifting. Fixed crane very busy bustling equipment around the site

P10/11 roof supports and roof sections turns out to have been the answer as 'ellendune' supposed - and they've installed almost enough so far to match the length of the P12/13 canopy, although eventually P10/11 will go much further along, as far as the present lift and stairs at least.
This is the bit I thought recently might be left for a while, but in hindsight they might have needed a line block lifting all that stuff over the new platforms once they became live, so it will make more sense to do the maximum possible now...
PS Regarding the Cow Lane bridge works, I wonder if for some reason they have had to replace what looked like waterproofing sheets? Backtracking through the webcam day by day suggests that might be what was done...
PPS - there's a structure appeared on the roof of the country end of the P14/15 canopy that looks as though it is part of an electrification gantry...

Definitely got an odd angle to it though?
I've been wondering how well they'll integrate the OHLE equipment with the overall 'look' of the station - perhaps they'll use cantilevers from the platform centrelines rather than heavyweight gantries stretching right across all the tracks and platforms?
We'll probably find out shortly...

OK it's a theatre and not a feather route indicator. And it was clear to me that the signal hanging from a pole on the gantry must only be temporary as it wouldn't have met CDM▸ requirements for maintainability. Finally, was the trailing slip between DM and UM just east of old P4 put in from November 1979 as well? And did the shunt signal R653 allow ECS▸ wrong line on the DM UM down to New Junction? |

Can't see how a cantilever from the centre would look any better than a gantry suspended between the centres. A gentry would allow the span to be lighter weight. |

You can't rely on the gentry to help out these days, what with the school fees and the possible mansion tax... |
