Looking at the images, was this section ever quad track at one point, being as there seems to be the space suggesting so?
This is where the LNW line to Peterborough diverged and went under the Midland a little further up. The path of the disused railway can easily be spotted on Google earth.

It was once four track from Market Harborough to Great Bowden where there was a junction where the LNWR Stamford route diverged by passing under the Midland:

Here’s an old map centred on Main St bridge:
That`s a much better reply than mine! Great map.

Wonder how the series 2 headspans will hold up, older ones have more of a tendency to fall down.
The 'headspans' that are new aren't supporting the catenary & contact in any way; they're just supporting the feeders from the new TSC.
They're just Across Track Feeders (or XTFs) - although they technically have the same acronym as Auto Transformer Feeders (ATFs), the 'X' is there to avoid confusion.

What's it called? It's called Cumbernauld

Did realigning back to the original Midland alignment west of the current line (the sidings on the old map linked above) ever make it into the MH straightening project far enough to later get de-scoped? (AIUI, that was the Midland's original alignment, before it was shifted to the current one to facilitate the later LNWR line passing under it)

It sounds like something's gone seriously wrong with this weekend's engineering works - both EMR and Thameslink are apparently going to be running an extremely limited service from St Pancras tomorrow. Does anyone know any more?

According to Thameslink's website, one of the 4 tracks is out of commission all day - the track in question isn't specified.
EMR's intercity services are 1tph each way between London/Notts and London/Sheffield, but Connect services are unaffected.
The Rainham - Luton Thameslinks aren't running, and the Orpington - Luton services are turning round at Kentish Town.

I suspect the track works at Harpenden are the culprit here, as any major OLE issues would lead to no trains at all.

According to another thread it's a ballast train on the down slow at Harpenden which hasn't dropped its ballast onto the new track.

Despite the issues on the track renewal project, Napsbury TSC, Radlett TSS and East Hyde Neutral Section entered into service at 01:54 this morning, with Sandridge TSC and Radlett decommissioned from the system.

The original intention up to c2016 was to relign all the way to the A6 bridge, using the older direct trackbed, closing the curved flyover. This would have given 110mph from the station rather than 85mph. In order to develop an achievable project, this was de-scoped, leaving the station platform straightening and wiring from Glendon Jn to MH.

The time saving would have been small on diesel but better now the wires are to go to Wigston. Indeed, it is possible that most of the 110mph limits will be raised to 125mph, when signalling allows.

Also, the flyover embankments are old and have two bridges, one skew. Not only is this a maintenance issue for the future but may offer challenges in piling. Whether the older route is clear from farm use is not clear.

It would have been better to ease the curve but it's even better to get the wires to Wigston.

I suspect this might become a project for consideration, if it hasn't already.

It was in the 1980s resignalling scheme and deleted at a late stage, after the people using the land had been given notice and cleared off. It was again planned in the 1990s, and again the users (the riding school by then, I think) were moved, and then privatisation intervened. Then it came up again with the station rebuilding, only to cut out in the usual not-London-South-East de-scoping. Thus instead of the planned 90 on the curve south of the station and then 110 through the station and on towards East Langton we're stuck with the 85 throughout dictated by the radius of the curve over the LNW-line bridge. I believe the ownership of the old route is still entirely with the railway. And even after it ceased to be running lines it remained in use as sidings right up to the 1960s. And it's a good expanse of levelled land ...

Excellent, thanks for the explanation

I think part of the issue is that 50% of the benefits are lost because at least half the trains stop at Harborough so won't be anywhere near line 85mph through most of this section.

The curved flyover could make a very useful southbound freight loop, if they ever were to slew the main lines back to the old alignment.
To be fair, the MML in this area is not short of opportunities for passing loops. There were 3- and 4- track sections North of Kilworth and between MH and Desborough - for instance the drawings of the new overline bridge recently built South of Harborough showed provision for 3-tracking.

Part of the gain is a slightly shorter route free of expensive civil engineering issues.

Agreed, can only assume that the condition of earthworks and bridges are good enough that the avoided maintenance/replacement costs were not enough to put the business case in the right place to do the works prior to electrification; although it does seem like a bit of a missed opportunity.

If I'm not mistaken, that means all the MSE-era cabinets are now either disconnected or modified from their original configurations.

Speaking of MSE, here was Bedford 40 years ago to the day (a few weeks before electric services started in earnest):

A year before that (1 May 1982), Cricklewood depot and its sidings (picture taken where Brent Cross West now is):

That same year, the wires reached the Barlow train shed (removed in 2000, and restored again in 2007 for the quarter-mile CTRL internationals):

And three years prior (May 1979 from Kimpton Road bridge), the tracks between Vauxhall Motors (left) and Gypsy Lane factories (right); now it's Luton Airport Parkway between the DART / HbH hotel and Luton Retail Park respectively:

Bedford - London (and beyond) commuter services have had five changes of electric rolling stock since then (317 / 319 / 377 / 387 / 700).

From my observations today, the gantries are slowly reaching Kilby Bridge. Still lots of de-vegetation works to be done around the South Wigston area by the looks of it.

yep. going through wigston junctions right now and there's still vegetation right up to the tracks

Press release


Network Rail is urging road users in Newton Harcourt to allow extra time for their journey as major work to upgrade two railway bridges takes place.

Network Rail is in the process of electrifying the Midland Main Line from Kettering to Wigston. This will help to create a cleaner, greener electrified railway for passengers travelling along this section of the Midland Main Line in the future.

As part of this work, bridges on both Fleckney Road and Wistow Road will be demolished and rebuilt to provide clearance for equipment needed for electrification.

Wistow Road has been closed since May to allow work on the bridge there to take place, and, from Monday, 26 June, three way traffic lights will be in operation on Glen Road to allow work to begin to the bridge on Fleckney Road.

These traffic lights will remain in place until Friday, 14 July. During this time, motorists are urged to leave more time for their journeys.

Fleckney Road will fully close to motorists on Monday, 31 July. During this time, a clearly signposted diversion route will be in place. The road will remain closed until February 2024.

The work has been planned to cause the least amount of disruption to residents and rail passengers, in collaboration with Leicestershire County Council.

Wow, none of these road or bridge names make sense. There is Station Road, Wistow Road and Newton Road/Leicester Road.
Maybe the railway works from maps that show what the roads were called when the railway was built!

Anyway, they seem to be getting near Leicester.
