All very encouraging, I reckon.
I must admit, that did amuse me too - grew up not a million miles from there. It's Laffak Rd, though, which I think escapes the forum censor. Problem solved
Still no evidence of activity at Carr Mill Viaduct just yet, save for some electrification related gubbins dropped at the side of the track.
Did a detour on my way back up the 'Green from town at dinnertime to have a look at Carr Mill Viaduct. As you can see from the photos (1 & 2), there appears to be something happening. The sign on the side of the compound fence says 'Everlast Waterproofing Ltd - Men Working Overhead'. Photos 3 & 4 show the underside of the viaduct edges and indicate that it's an interesting engineering challenge for mast placement/anchorage when you consider that the grid structure must be the walkway either side of the tracks.
I'm not sure which correspondent it was, but yes, there were originally 4 tracks - up/down fast and up/down slow, the slow carrying mainly colliery/freight traffic to the numerous colliery spurs along the line. At the South end of the viaduct, just past the small Laffak Rd bridge was Carr Mill Junction, where the line split. One two track section carried on towards St. Helens Shaw Street (now St. Helens Central) as now, the other tracks formed a freight avoiding line which went around the East of the town eventually joining the St.H Shaw St to St. H. Junc and Widnes tracks at Sutton Oak and also serving a couple of collieries en route. From the northern side of the Carr Mill viaduct, the lines continued four-tracked to Garswood and beyond.
TfGM saying Liverpool-Airport electric service delayed into early 2015 but will commence as soon as work completed and before May timetable change.
"Nuff Sed". Very clever.
Some spectacular pictures there. I like the creatures of the forest. But I especially like the views east from Victoria, particularly the telephoto one, which is interesting to compare with the bird's eye view that you can get on Bing Maps.
I'm not sure of the current state of the works to rebuild Rochdale Road bridge. Last time I was there the old bridge was still there. Is the pale bridge in the picture Rochdale Road? Or is it the road beyond, Osborne Street, which was rebuilt first?
Aha! progress, the fencing wasn't there on Wednesday.
Very interesting to have clear local knowledge, not least, I suspect, from a fellow 1949-er!
Thank you.
I have to disqualify you for trying to sneak Eyemouth in twice and mis spelling Knowsley.Headingley

I'm not sure if this site has surfaced before, but it gives quite a comprehensive list of electrification mast codes
http://www.railwaycodes.org.uk/electrification/mast_prefix.shtm
Still doesn't explain how Huyton to Wigan becomes 'HG' (now we can guess!) - apparently 'LW' was allocated but not used !
The main site - Railway Codes - is also very useful for other information
http://www.railwaycodes.org.uk/index.shtml
Yes, this fab site has surfaced before, but it can't do any harm to extol its virtues again.
I don't know how Huyton-Wigan became HG, but long experience of the ways organisations I've worked in dream up codes suggests an interplay of the following:
National precedent, eg going alphabetically round the lines radiating from London similarly to the way roads go numerically round, (A1 North, A2 South east, A3 South Westish, A4 West etc) This is fine until someone has the impertinence to build a road or electrify a line not originating in London.
National secondary precedent, eg lines branching off a line from London start with the code for the line they branch off and add a letter which may (or may not) be mnemonic. So G is the WCML out of London (alphabetic) and GL is Weaver Jct (off the line G) to Liverpool (L). This is fine unless there were also a line off the WCML to (say) Luton, in which case something like GN (G to LutoN) might be invented. It is also complicated by the inconvenient fact that many Weaver Jct to Lime St masts are coded L (see the database.)
Regional precedent, eg going round the lines radiating from a city outside London, such as Glasgow, so the WCML line south from Glasgow is G either on an alphabetic principle or a mnemonic one. This is fine until G (WCML from London) meets G (WCML from Glasgow) when mast numbers are discontinuous, if that matters. It might be less fine if there are several Gs dreamt up independently which could be confused, such as G (Glasgow), G (WCML) and G (Glossop.)
Silo coding, eg different eras (eg the three Gs mentioned above) and different departments (electrifiers, line engineers and database builders) have different working practices. Line engineers have had a universal, copper-bottomed, time-honoured "Engineers Line Code" (ELR) system operating since the 19th Century which uniquely identifies every line and every structure past and present. Just look at codes on bridges shown by printed signs or metal plates (eg Eccleston Park Bridge, see attached) or stencilled paint. Electrifiers or electrification designers or contract database builders have invented mast codes independent of the ELRs. In different eras we have Lime St-Hull being coded LH, with of course, the vast majority of it not being electrified. Our electrification scheme, however, has used LM for long infill sections such as Whiston-St Helens Jct even though LH was "allocated" to the route years ago.
Pick a letter, as long as it's unique, eg take the view that as long as a stretch of masts is clearly identified and each mast is uniquely identified it doesn't matter what letters are used.
Cherrypick rationales, eg Huyton to Wigan could be:
LHW LH to Wigan
LHG LH to G WCML
LMW LM to Wigan
LMG LM to G WCML
no, blow that, only two letter codes are permissible
HW Huyton to Wigan
HG Huyton to G WCML
or
HG Huyton to G the first gap in the alphabet noticed by the person doing the coding.
It seems obvious from the outside, afterwards, not being responsible for it or in the thick of it that piggybacking mast codes on ELRs would be a good idea. Well, it would be if the people designing electrification talked to the people maintaining bridges and tunnels. I'm sure they do talk to them, frequently and largely amicably, but that does not necessarily translate into having compatible software or systems. This departmental "not talking to" is not a criticism, but a fact of life.
ELRs have well over 100 years of solid provenance. This means that there is over 100 years of complexity, change and confusion in there. Using ELR codes, Huyton Jct to Wigan consists of all or parts of SBH1, SBH2, SBH3 and CGJ5 and, to add spice, the Huyton Junction datum point has moved 15 chains.
For an electrification designer to associate masts with ELRs would require him or her to have access to an exact, unmoving, ELR-based database into which s/he could input precise details of the location of a mast or other structure.
Probably more difficult in the real world would be the fact that ELR codes can be 3 or 4 characters (eg DSE and CGJ5) whereas an initial design spec for mast codes would be LL nn nn where LL are two letters. On such things empires tumble.
If I Ruled the World all codes would be meaningless, so masts 123456 and 234567 could be neighbours or 100 miles apart. They would, however, be guaranteed to be unique and identifiable by anyone with access to software saying where it stands, such as precise GPS data.
There was a large crane below Carr Mill viaduct on the north side - impossible to see what it was doing.
A good sign nontheless.
BTW, I got a response from NR regarding the delay to phase 2, which reads as follows:
'Thank you for your recent enquiry as noted below. In reply, I can confirm that at present we expect the work to electrify the line between Liverpool and Manchester to be completed slightly later than originally planned. But we are working closely with Northern Rail to ensure that there is little, if any, impact on passengers.
The delay has been caused by the unexpected ground conditions and technical issues with the wiring equipment that are now being resolved. In response, we are making every effort to ensure the work is completed as soon as possible and expect it to be completed by early 2015.
We will keep people informed as the work progresses.
I hope this helps.'
That's identical to the quote in Rail last week.
You can never be quite sure what's going on underneath.
The pressure's on, for sure.

I like it!
Another nice steady flow of news today:
Carr Mill Viaduct: scaffolders in action
Earlestown: another portal erected off the eastern end of platforms 1&2, another mast over the W-S single line. An Orange Platoon were taking 10 metre deep soil samples from the site of one of the masts-to-be on Platform 1
Sankey Viaduct: Scaffolding complete on Column 7, both sides; team will return from Carr Mill tomorrow
Huyton Jct: possible evidence of excavation on bus station side of the fence opposite the eastern end of the trackside path. Can a local have a shufty?
Roby Jct-Roby: more masts up; masts between tracks have sprouted arms
Roby-Huyton: more masts up
Huyton Quarry: regret I erred last week when I reported that the lone bare base had had a mast plonked on - it hasn't
Rainhill: at least four of the scrapes have bases curing in formers.
I'll add photos later tonight.
Progress. this is what we like to see!!Twenty new photos here:

I clearly think they're embarrassed, but it would be better to come fully clean over this in my opinion.
Come clean and give another date? Last thing you want when you're running so late is give yourself another deadline. Currently plan is working in time for May, bit hopes of much sooner than that.

I have a feeling somewhere about January-March for Wavertree to Earlestown.
