I counted 58 (probably more) masts on the south side from the end of current wires near Victoria to just west of Ashton under Lyne.
All sorts of structures, from single track masts to twin-track to gantries, in various states of fit-out.
Quite a few were sporting registration kit and tensioning gear.
When the masts run out at Ashton, piles continue over much of the rest of the route to within a quarter mile or so of Stalybridge Jn (alongside the Guide Bridge line).
The Guide Bridge route itself also has a good number of piles, perhaps 20 on the north side of the layout.
Nothing yet at Stalybridge, but they are making excellent progress.
