I visited Huyton this morning to find another new signal erected, on the Up Slow a little east of platform four. It has a position 4 feather for trains heading to the Chat Moss lines (It's the far one in this picture.)
More importantly, and just about visible in the picture above, the overhead for the fourth line is in place. To the untrained eye it looks complete - catenary and contact wire, and I couldn't spot any temporary pulleys etc.
I'd forgotten how much more copper-coloured and shiny new overhead is, it was obvious from some distance away that some had been put up, as soon as I could see the line.
Update: Lo and behold, a few hours after I wrote the above, the signal's plate has been fitted! LL5580. Coincidence, or is someone reading this blog?
