What diversionary capabilities would those be? Until the whole of the MML is done, anything using RS3 OHLE would have to be bimode, surely?
Don't shoot the messenger please. I am just quoting almost verbatim what the Modern Railways article stated. I struggled to see also. But will have another look to see if I am missing something obvious. It stated diversionary - not electrified diversionary.

Apologies, i didn't mean it to come across that way. I'm genuinely curious. Perhaps they mean that with RS3 being on a four-track section, you can divert traffic onto the slows when wiring the fasts and vice versa?

I am assuming, yes, it is something like that - or get the more difficult bit out of the way first. I don't care as long as it gets done!!

This is an ideal battery candidate surely.
But it seems like an easy to do electrification that can easily be added onto a much bigger scheme. Batteries are a solution to a problem that shouldn't exist.

I'm afraid I would disagree with you there. Matlock has only one train per hour, which would never justify electrification by itself. And Matlock-Newark Castle is a perfect candidate for BEMUs, charging between Derby and Nottingham twice per cycle.
But then you have the likes of Largs, Wemyss Bay and North Berwick, which like Matlock receive 1 train per hour, are single track and were tagged onto a larger electrification project to enable more use of electrification on a principle route. In more recent times there is the now shelved Cardiff to Swansea electrification which was only immediately going to be used by one IET per hour.

All very well quoting miles of battery range and tailoring units to suit.
What happens when Battery degradation kicks in?
If current performance of commmercial road vehicle batteries is anything to go by, degradation is graceful and predictable. Also lower capacity is not a cliff edge, typically 10% after 500 full cycles. On-board battery charge management (particularly in a bi-mode OLE/battery operation) is unlikely to regularly push the battery to full charge or near full discharge, given that power/range allowance must also be made fo winter/summer differences. Thus useful operational life of the batteries is likely to be compatible with established maintenance and overhaul practice.
What is does mean though is that suggestions of planning long autonomous energy running with minimal recharge opportunity in service is an unrealistic profile with current technology. So as @edwin_m says, Lincoln would be likely the limit of autonomous energy running.

Now that Bedford to Corby has been wired, and Kettering to Wigston is ongoing, are there any recent figures for the costs of electrifying the MML?

== == ==

As a separate observation, when searching for published figures, I did find the minutes of the Transport for the East Midlands board meeting in June 2020: https://www.emcouncils.gov.uk/write/15_June_TfEM_final_papers.pdf

Section 10 "Completing the Electrification of the Midland Main Line" of the Submission by the East Midlands HS2 Executive Board (p26) makes interesting reading:

10.7 Analysis of information publicly available in the House of Commons Library suggests that the cost of operating bi-mode trains is around 50% less per mile in electric mode than in diesel mode, due to lower fuel costs and reduced engine/track maintenance costs. As a result, the evidence suggests that if the capital costs can be kept below £3 million per mile (2010 prices), the BCR for incremental electrification of the MML with bi-mode trains would be at least 2 to 1.

As part of the Midland Main Line electrification, Network Rail will start to drive steel columns as deep as seven metres into the ground to lay the foundations for the overhead line equipment needed to power electric and bi-mode trains in the future.

The multi-million-pound programme supports the Government’s ambitions for decarbonisation and aims to deliver a greener, more reliable railway to connect passengers right the way between London and Sheffield, via Nottingham and Derby.

The route between London and Corby has already been upgraded and electrified in 2021. This next phase of major work will see a 12-mile section between Market Harborough and Wigston brought up to speed to eventually connect the entire route

Looks like some fuzzy thinking here. Train maintenance costs will no doubt vary depending on how much the diesel mode is used, but the track doesn't care. Those costs only reduce if a lighter train reduces wear and tear, so I wonder if they are getting confused between a bi-mode operating on electric and a pure EMU.

A reminder that this thread is exclusively for the discussion of actual progress updates regarding MML electrification please.

If anyone wants to discuss anything else the please either start a new thread or find an existing one.

As @Nottingham59 has pointed out discussion of Battery Trains can be made in this thread:


Some other posts of a speculative nature (including posts which subsequently quoted and/or referred to such posts) have been moved to:

Somewhat surprised to see the Market Harborough to Wigston start now compared to the trans Pennine electrification between Leeds and Church Fenton (though that has to have a lot of work done).

Bear in mind that it is possibly a "major" phase if its completed and "minor" phase if it is shelved !.

But it is good to see evidence of steady progress Northwards.

Certainly!
then again when it's completed all the way up to Sheffield, There is the incentive to connect other electrified routes. But thats far in the future when the MML electrification is entirely done. It's also a discussion for another thread...

Meanwhile, at the Braybrooke Supply site, all the major work seems to have been completed and both sides of the 400KV pylon have the double angled insulators to hold the main cables when the connecting cables go to the transformers. There is also a big crane finishing off work on the new bridge to the South. There are now piles in the ground for the masts.

There is still no sign of piles/masts, cantilevers etc through Desborough but everywhere else (apart from Braybrooke) now seems to have cantilevers and "dangles" of insulators. There are some earth wires in place as well.

Indeed, seeing the work that's been involved with this it's very apparent why FS are not cheap.

I'm also consistently impressed with how tidy the works on the MML looks in all these update pictures, compared to many other main lines with cables, troughing lids and other detritus strewn everywhere seemingly without a care.

Good to see that the lineside eqipment seems to be been built far enough back to allow a southbound passing loop on the old alignment, if one were ever needed.

Southbound freights are severely constrained between Leicester and Kettering, according to the MML Congested Infrastructure Capacity Analysis (2020 2015):
https://www.networkrail.co.uk/wp-co...d-Infrastructure-Capacity-Analysis-240315.pdf See section 2.4 Kettering to Leicester.

Let's just hope that the pilings for the OHLE don't block the alignment ....

I expect any space for a loop is entirely coincidental, and instead they're maintaining the road vehicle access track. The signal gantry is in a very awkward position for a loop, for instance.

The national grid aspects of the work, including the alterations to the main pylons, have also been very interesting to me. That’s more usually happening well away from the railway so gets very little coverage.

Many thanks again to @Flying Phil for regular news from this location.

The piers of the bridge (bridge 28E) look solid enough for the deck to simply be swapped out for a new one IMO. And based on the area, there'd be little point making this footbridge brand spanking new with step-free access when a level route exists via Main St (bridge 28D) anyhow.

Most level footbridges in semi-rural and rural areas tend to be for use by horse and rider too, rather than by wheelchair.
And even if a horse rider/wheelchair user navigated their way through Great Bowden Field to the bridge's western edge, they'd have a time and a half getting past the kissing gate on that side...
Accessible kissing gates are easily obtainable and can be installed by gangs of retirees! ( I've done several)

Press release on work to the platform canopies at Chesterfield station. Electrification compatibility not mentioned. I hope it has been checked for.


This week, work is underway to fully refurbish Chesterfield station’s platform canopies and revitalise the station for the thousands of passengers who use it each year.

The existing canopies on both platforms will be replaced with new fascia boards made from a stronger, more durable material and the metal work will be cleaned and repainted. The 19th Century style canopies will also be repainted to offer a bright, refreshed look.

When complete, passengers will have an updated place to keep dry and sheltered as they wait for trains headed towards Leeds, Nottingham, London, Glasgow, Sheffield and more.

Until Summer 2023, engineers will work through the night to deliver this transformation allowing trains to continue to run as normal during the day.

Long overdue. They were becoming increasingly dilapidated in flaking old Midland Mainline green paint, though were probably good for a few more years if repainted.

The current canopies may not be electrification compatible so hopefully this is an opportunity grasped in good time to make that project easier.

Engineering works soon to take place in and around Market Harborough, although some dates likely to be postponed due to planned strike action.

Is there any idea if at all that the electrification in the Trent junction area will extend to the various freight sidings and yards such as ratcliffe on soar power station and the east Midlands gateway?

Theoretically Ratcliffe will be shut by 2024 but who knows if they keep it going beyond then but as imports come across from Immingham would be diesel anyhow. East Midlands Gateway certainly should be wired but hasn't been a policy to enable electric haulage of freight as nothing is electrically hauled in the Western but lets hope the likes of GBR and ROG with their new build electro diesels forces a change.

It’s not going to either, not least as Ratcliffe is due to close long before the wires get there.

Gateway - no point as the trains that use it will still have long stretches of unelectrified route to traverse to get there, so will remain diesel hauled.

Press release


This December, Network Rail is investing in the East Midlands’ railway to bring better stations, more reliable journeys and to power ahead with the Midland Main Line electrification scheme.

On Saturday 3 and Sunday 4 December, the brand-new second footbridge will be lifted in at St Albans station to make it easier for passengers to move around during busy times.


Over the next two weekends (3, 4, 10 and 11 December), engineers will also be making progress on the multi-million-pound Midland Main Line electrification scheme, which will see the train-powering overhead line equipment upgraded south of Bedford.


Major work is also taking place to lower the tracks through Main Street bridge in Market Harborough to clear the way for overhead electric wires to be installed in the future. The programme supports the Government’s ambitions for decarbonisation and will ultimately deliver a more reliable, greener railway.


This will mean changes to services between Luton and London St Pancras across both weekends, as well as replacement buses between Leicester and Kettering via Market Harborough on 10 and 11 December.

I assume that by "Main Street, Market Harborough" it means Main Street, Great Bowden.
