The target price quoted is a third less than that achieved for the Bedford to Kettering project (2.5m ptm against 3.7m). Hopefully these are after adjusting for inflation, else it becomes an even more challenging task.

What’s the likelihood the answer is that nobody can deliver to those costs and the govt shrugs its shoulders and says “not our fault it’s not going ahead, if the industry can’t rise to the challenge).

There's some very expensive work needed if remodelling places like the approaches to and platforms at Sheffield are included.

Those living in Bristol and Swansea may recall how quickly fully electric services arrived there - not!

Kegworth was applied for over a year ago. Don’t think Chesterfield has been applied for yet.
Do we know where is the Kegworth grid feeder planned to go? The site chosen by HS2 for the 400kV to 25kV transformers has now been overtaken by the Local Development Plan around Ratcliffe power station.

Especially since Bedford to Kettering was four track, which would be expected to have lower costs per stk than the two track sections north of Trent.

And Leicester - the plan has been to skip the section between Wigston & Syston because of potential Leicester remodelling, although that seems to have gone very quiet post-Covid so presume the plan is now to wire Leicester and hope that any future capacity scheme doesn't have to knock half of it down again.

I've access to a GIS system with Land Registry INSPIRE data, so I had a look and what's interesting is the land with ID 52504166.
The Land Registry website, gives a description, "land on the East side of Kegworth Road, Ratcliffe On Soar", last bought/sold on 1st October 2012 - coincidentally just after MMLE was announced in mid-2012. INSPIRE searches do not tell you who the landowner actually is though. That takes money and I'm not that curious.

The picture below shows the area (sketched out using Google). It's outside the boundary of the Ratcliffe Development Zone and has a transmission tower on site, which is convenient.
It might not be, but it does look pretty suitable.

Footbridge has now reopened at Great Bowden. Cosmetically it doesn't look great but it serves it's purpose.

Surely they could have shot-blasted and painted it at the same time. They'll have to come back to do that in a few years. which will cost more. The trouble is that that cost will come from a different budget

I had understood the lattice bridge at Great Bowden was going to be removed and replaced in its entirety - is that not the case - if so, good news, it’s an interesting structure!

I've got a photo in a book looking north from the next bridge south taken in 1900 you can see the same bridge, so its been there over 120 years.

Well, it looks like the AT upgrade of Kettering North is now complete!
Good stuff.

Which reminds me, the delivery of the Wigston South cabin(s) can't be far off now. Any idea when that's due - Christmas, perhaps? (EDIT: Not included in today's NR presser, so perhaps not.)

Presumably it was originally planned to be a SATS, then converted to a TSC when the wiring was cut back to Kettering/Corby, then converted back to a SATS?

Another tidbit of news relating to MMLE!

Testing and commissioning work for Braybrooke ATFS has taken place, certainly for the second HV circuit as this LinkedIn post shows - video embedded.

Based on a quick scan of AIVR, most ATF wires are now in place, but the cables and sealing ends seem to be the main outstanding component of works.

Wasn't expecting the Hendon-Luton phase (ahem!) of OLE125 to start this year, but apparently it will; at least between Hendon and Mill Hill Broadway over the Christmas break. At the same time a Permanently Earthed Section will be installed at Kettering North Junction.


Wednesday 6 Dec 2023


Upgrades on the Midland Main Line continue over the festive period​

Region & Route: Eastern | Eastern: East Midlands
Essential work will continue over Christmas to prepare the Midland Main Line for electrification between Kettering and Wigston as passengers are advised to check before travelling on 27 December.

Teams will be installing overhead line equipment along with completing essential work to install a Permanently Earthed Section (PES) at Kettering North Junction. A PES is a section of overhead line which is kept permanently earthed, meaning no electricity is running through it. It’s being installed to keep everyone safe while teams continue to work on overhead lines and to prevent any power straying from adjacent sections of OLE that are already live. This will be removed before Network Rail energises the Kettering to Wigston section of the line later in 2024.

Most of the work will take place on Christmas Day and Boxing Day when no passenger services run. Due to the complexity of the project, some of the work will continue throughout Wednesday 27 December, affecting services between Corby and Wellingborough.

Buses will replace trains on 27 December for passengers travelling between Leicester and Kettering via Market Harborough.

Gavin Crook, Principal Programme Sponsor for Network Rail’s East Midlands Route, said: “We appreciate there is never a good time to disrupt journeys and whenever possible we complete our work at times when there are significantly fewer people travelling by train. By completing this work over Christmas, we affect passengers for one day, instead of three.

“We are sorry for the disruption this will cause and ask passengers to check their journey before setting off on 27 December.”

Dave Meredith, Customer Services Director at East Midlands Railway, said: “This work is a vital step in electrifying the Midland Main Line and another big green investment in the region’s infrastructure.

“We would like to apologise to any customers affected by the works and would urge them to double check their journey if they intend on travelling on December 27.

“To help keep people on the move, buses will replace trains between Kettering and Leicester via Market Harborough – as well as between Wellingborough and Leicester. An amended train service will also run between London St Pancras International and Wellingborough, Corby and Sheffield, Leicester and Nottingham, and Leicester and Sheffield.”

Electrifying the line between London St Pancras and the East Midlands will allow the introduction of bi-mode trains in the future, delivering greener, faster, and smoother journeys for passengers.

On Christmas Day and Boxing Day Network Rail will also be renewing a section of overhead line between Hendon and Mill Hill as part of an ongoing programme of work to upgrade the power supply south of Bedford, these improvements will allow trains to run at 125mph.

Only because you would be lost and have no idea where you were if it went :lol:

That would seem to be the case!
Worth remembering that all the new substations between Kettering North & Borehamwood were also originally scoped for being built with AT from the outset, but the onsite elements of AT feeding were descoped.
Napsbury, East Hyde, Long Meadow Farm, Ampthill, Bedford, Sharnbrook, Irchester & Harrowden can all feed in AT format if the appropriate electrical gubbins is installed.

Is that an over-enthusiastic press release or are NR actually planning on increasing the line speeds in that area - there's currently no 125 running south of Luton IIRC

There is around six miles in each direction between Elstree , through Radlett and just before St Albans

Maybe a tad over-enthusiastic, but "up to 125mph" has been the general gist of things. Even outside the aforementioned Borehamwood-St Albans stretch there's a mixture of linespeeds above the 100mph Mk3b OLE ceiling that electric rolling stock cannot take advantage of at present.

Between Cricklewood and Borehamwood it's 110mph (save for a 105mph stretch through Hendon).

Also 105 then 115 after st Albans then 110 , 105 at Harpenden northbound. Then 105 , 120 through Harpenden southbound. In fact after Cricklewood the only speed at 100 is through st Albans and approaching Luton. All the rest is above.
