Wonderful links, thank you very much.

Yesterday I had the pleasure and privilege of a guided tour of several worksites between Preston and Blackpool North, by kind courtesy of Network Rail.
I had a list of prepared questions which my host has agreed to answer with thought rather than off the top of his head, I'll publish his replies in due course.
On site he used my camera to take the shots linked below.
Throughout the afternoon he spoke with impressive knowledge and understanding of the project, plus good humour and tolerance of a lay numpty.
The $64000 question he had no difficulty with - "Are we 'on' for Blackpool South at the end of January and opening for electric trains in March?" Unequivocal "Yes". Problems of supply have been resolved, the cause basically being the sheer scale of NR's projects across the land; the other threat was, as always, the weather, but the Met. say it will be generally mild for the next three months.
Please note: being open for electric trains does NOT equal electric services WILL run then, it means they CAN run from then. Presumably there will have to be training, testing and goodness knows what before the timetable change in May, when sparks should fly.
The photos are in the Combined Volume here:

Warm thanks to NR and my fine, friendly and professional guide.
