Different names in different areas?
Cheers that's cleared that upJack hammer in use Werrington Junction Upgrade 19th June 2020
After vibrating steel piles into the ground a few days ago under the Cock Lane footbridge where there is limited headroom, shorter lengths have now been welded to them and the hammer is being used to sink the piles further.
Probably about the same time a flying junction became a flyover. Is this terminology imported from the road industry?How, when and why did a burrowing junction become a dive-under?
Retford (not a junction of course) was referred to as a dive-under back in the 60sDifferent names in different areas?

Very interesting pictures. I know that only the line towards Stamford was electrified before the work, but surely with a new works done and the lines being moved, why didn't they electrify both the Stamford lines? I am sure that there are some good reasons, but to me it seem to be a basic way of extending the electrification in a quick and easy way.
But historic mapping suggests there were more tracks on both ECML and Stamford routes in the past. Perhaps it was rationalised at or before the ECML electrification.
I think it was a WW2 rationalization.As noted in earlier comments, the Down Stamford doubles up as the ECML Down Slow. The Up Stamford is not electrified.
Nevertheless, the ECML Fasts and Down Slow will presumably have to be closed at some stage during the works. Noting there is presently no connection to the Up Stamford from the Up Fast, might it not make sense to provide a connection and electrification of part of the Up Stamford to allow the ECML to remain open during the coming works?
Forgive me if this has been covered previously.
The present layout predates electrification as I recall observing it on journeys from Dundee to Kings X in the early 1980s.
Maybe a dive under is just one component part of a burrowing junction. Same for flyover and flying junction.Probably about the same time a flying junction became a flyover. Is this terminology imported from the road industry?

Siemens & NR are working to modify the interlock at Helpston to allow some services to run bi-di over the chord linking the Stamfords onto the Down Slow, and thence making the Down Slow provisionally bi-di to Tallington AIUI.The geometry probably makes any such connection near-impossible without killing the line speed, due to the track cant through Helpston.
Plus installing such crossovers would themselves need an ECML closure...which is a bit pointless when it's only a week blockade (I think) required anyway, and the route via Spalding is still available.
AIUI that’s referring to a couple of pilot or guide tunnels, which will be tunnelled under the ECML as they say, but they are effectively temporary works for guidance of the jacked box. When the jacked box moves the embankment just ahead of its front face gets completely dug out.Network Rail seem to suggest it will stay open...
‘ When fully assembled the 65m long TBM will bore the two 168m long tunnels under the live operational East Coast Mainline (ECML) which will be running at 125mph.’

On RTT I see there are engineers trains to Werrington Jn. starting this Saturday 18th July.
Saturday the 8th August there are no passenger trains between Spalding and Peterborough so can it be assumed this is the weekend when the connection from the Joint Line to the dive under line ( ? Glinton Junction ) will be installed.

It’s switched on to show when the driver has his seat belt on, and the machine is going to move.I notice that besides Amber winky pots on various machines, some also have green ones fitted. Does this indicate something?
On first seeing this on a Dozer I thought maybe to indicate working to Laser control, but then another machine a Dumper also has a green winky pot, so that possibiity is out.
Any thoughts?
