Notes
Edge Hill to Wavertree only new mbs shown, older masts also exist
Bryn to Wigan NW only new mbs shown, older masts also exist
Ince Moss branch bases visible
mbs in stations not shown, eg Prescot has two large "arch" masts
The rock 'canyon' N of Eccleston Pk will have side fixings, not mbs
Nothing on or east of Sankey viaduct.
Roby-Huyton requadrupling and station work moving forward, notably:
More ballast in readiness for third track, some is levelled.
More sleepers laid awaiting track, others stockpiled in readiness.
cwr in the eastbound 4' awaiting laying.
There appears to be ballast or hardcore building up the piled embankment between Roby Junction-to-be and Roby Station.
Foundations are being laid for a structure immediately west of the bridge at Roby, between tracks 2 and 3.
Roby lift shafts coming on apace, shuttering and steelwork awaiting concrete.
Roby platform edges and extensions to new height and distance from track plainly visible.
Huyton third and fourth platform edges well advanced.
Huyton platform 1 raised and realigned along its full length.
Work in progress on liftshafts.
Preparatory work for third track visible east of Huyton Station.
Points which were laid on the long-disused S to W platform at Earlestown have disappeared, but not been laid west of the station. Have they been used at Earlestown South junction? This is not visible from public areas at Earlestown.
Track panels, sleepers, ballast and points laid to south of tracks between Earlestown station and Five Arches Viaduct, awaiting laying.
Lots of movement, the most visually striking being the masts in the Bold Colliery area with photos kindly published elsewhere on this thread.
