Laura Trott (MP for Sevenoaks) has posted on Facebook that from the December 2026 timetable change, Sevenoaks will return to 6 fast tph to London all day (presumably meaning the Charing X - Tunbridge Wells trains will go back to running all day, as they did pre-COVID). At the same time, air-conditioned trains are to be introduced on (at least some of) the Tunbridge Wells trains (i.e. not Networkers), so presumably there'll be another shift around.

Quite where this stock is coming from is a mystery - perhaps the 375s and 377s which berth at Grove Park between the peaks will be used, with the Networkers relegated to peak time only?
i think the truth has been stretched there a bit, i reckon its the Hastings services that run as 12 car are splitting portions at Tunbridge Wells and they are running some of the off peak returning 2H services as 4 car 375s to then be joined up again to the Hastings services in the PM.

The Networkers that operate early are probably swapping out to Slade Green for maintenance between the peaks
It’ll most likely be a return to the pre-Covid setup where a peak Hastings to Cannon Street service would then form a Tunbridge Wells from there, spend the day doing Tunbridge Wells to Charing Cross before going to form an evening Cannon Street to Hastings working.

Do we know if the all-day Tunbridge Wells-Charing X services will return on Saturdays as well? At the moment they only run in the morning, and as it's off peak all day I'm sure Southeastern could put more 375s on this route on Saturdays if needed.

Apologies if I am repeating information posted elsewhere but noted 2 April 2026 that 466016 is no longer at its long-term resting place at Doncaster Works, where it has been clearly visible from passing trains for many years, as oft-reported here.

More importantly, does anyone know what is happening with the tender for the new trains?
There were unconfirmed rumours few months back that an award could happen this summer, but all gone quiet.

Of course there is a finite train building capacity depending on which company gets the contract. Scotrail were expected to award their EMU/BEMU order about May, Northern's order seems to now be early 2027. But in meantime have been massive rolling stock orders in Portugal, Berlin, etc and various European countries already in 2026. Ireland announced an Alstom order just before Christmas to replace all its original Dart trains too.

Tenders and bids and indications might have gone in before these other orders around Europe were confirmed, so high chance some prices and/or timescales have moved.

What is no longer clear is how all these other European orders have blocked component factory capacity for months/years. If there are hold ups on parts (and could be anything from wheel bearing to door mechanism etc) then could be big production delay. And of course the longer it takes to order, the more the chance that others have got ahead in queue for factory production slots to build vital components.

If I was asked to guess, if the order is adapted Euro design, think it will be minimum 4 years to enter service, if new untried design, at least another 6 years before enters service. So sometime around year 2031-2033 when passengers can use them.

You are probably tad optimistic, especially looking at recent fleet introductions in the UK. The way things are going many more Networkers will go to junk before we see the new fleet.

Personally I’d like to see the 458/4 move to Southeastern eventually. This should see off the remaining 465/9s and 466s. The could replace them on Gillingham/Tunbridge Wells stoppers. Plus Soitheastern already have maintenance contracts with Alstom.

If they are not good enough to stay with SWR due to reliability problems, Southeastern will want to stay clear of them. They were fine with 707s as they were relatively new, but even then they were kind of dumped on SE, but another fleet that brings a load of new training, maintenance and platform testing requirements that is different to others, as well as being older, won't help them. It's more likely that they try and get more 377s off of Southern if they need to get rid of more Networkers before a new fleet does, as at least there is already compatibility here.

Another case of our dithering combined with no longer having sufficient home-grown factories is costing us more overall.

Spot on. We should be self sufficient in this country when it comes to rolling stock, buses etc. Its pretty criminal. It should be one of the first things this labour govt shouldve looked into especially with nationalisation on the horizon. The country needs 3 types of train. With long term build strategy (IMO mk3s should still be being built, updated as required).

... 2nd generation DMUs need replacing very soon. Get ordering and get building. Cascades Will work well as new stock comes on stream.

I’m not entirely sure where SE are heading with the Networkers.

If the strategy is simply to get rid of as many Networkers as possible, as is seemingly the case, then what is going to keep the service moving until the new trains come? So each pair of 707s replaces 2x465 and 1x466x so that’s 30x465 and 15x466. I’ve lost track of how many Networkers have been scrapped, but it must be starting to approach that number now, and on top of that there seem to be a number of units stored out of service as well.

Then there’s the 377s from Southern, however I thought this was for additional capacity, not as a Networker replacement. It’s a bit cheeky taking units off GTR, who themselves lost over 80 units off the back of Covid, gained 30 (not yet all in service), lost 377s to SE, only to allow further scrapping of mid-life trains.

If feels like the end-user is some way down the priority list in all this. Meanwhile the 465 fleet feels like it has been unloved for its entire working life, bare minimum done to it, and seemingly binned off at the earliest possible opportunity well before a replacement fleet has even been chosen let alone built. The malaise which seems to have hovered over Southeastern metro pretty much throughout privatisation seems to be showing no sign of disappearing.

Surely it was to get Networkers off the mid distance services, which means they are then predominantly used for Metro services. The GTR business case for using all 30 379s has been justified in part by being able to send on the 13 377s to Southeastern for further Networker replacement. There is nothing particularly wrong with that approach in a time of limited availability of funding.

It must be the case that the smaller the Networker replacement fleet needs to be, the easier it will be to get approval when it actually comes.

I think around 30 x 465 have gone but there are only 16 x 466 left in service, out of 43. This has drastically reduced the scope for 10 car Networkers. Currently 11 are diagrammed.

Southeastern have offloaded 25x 465s and 27x 466s from the MetCam side, which is 154 carriages. 30x 707s brought in 150 carriages, then 13x 377s added another 52 carriages, so this gave SE an additional 48 carriages, equal to 12x 4-car units, vs their pre-covid fleet size.

However, this is not accounting for the first BREL units going to scrap and some in de facto storage, so at the moment the total is probably close to zero net change. At the moment this is not a problem, however, a new fleet order needs to get a move on as Southeastern will need it ASAP, especially with improvements to the timetable from December increasing demand, and in turn maintenance costs, on the fleet they do have. The additional 377s haven't actually replaced many Networkers, as the Maidstone East line since 2022 has seen a major capacity uplift with the Charing X services, and looks set for evermore increases in December too, with the line returning to at least 3-4tph all day west of Maidstone, something not seen since pre-HS1, an unlike then, almost all services are 8-car, not 4-6 car.

What is the general consensus from a SE metro user when a 707 turns up on a service instead of a 465/466?

Do we anticipate the longer distance electrostar (375/377) fleet being used on metro services at some point?

depends on the season. In the summer a 707 is preferred due to aircon, but 707 or networker over 376 every time. I time my commute to avoid 376 wherever possible

It would be nice to know what the strategy actually is, when it comes to scrapping Networkers. Is it literally on a like for like basis, so that an equal number of Networkers carriages are removed as SE gain 707 and 377 carriages, will SE have a net increase in carriages or indeed will there be a net reduction?

And as a mixture of units have been withdrawn, it's not as if just the GEC ones are being withdrawn.

I would imagine that units will be and have been scrapped for primarily one of two reasons:
1) The unit is beyond economical repair
2) There is not the space to store said unit as new stock comes on stream.
They may have scrapped the full quota of units whenever a new fleet has arrived (707, 377) and then also scrapped further units as they become beyond economic repair. But, they might have left some 'extra' units so that when units failed later on, they could scrap the worst ones as required and still have enough.

1) might be beyond economic repair, but why did their maintenance regime allow just certain units to deteriorate and become uneconomic whilst others are still economic to repair. If economic to maintain, why not look after all of them.
2) No operator should ever cut the sidings to a point where any disruption or an extra train means can't accommodate it.
Doesn't make any rational sense to have extra units then plan to fail some later. Cheaper just to get correct number and ensure have stock of spares.

I imagine the withdrawn units will have suffered a severe fault i.e. failure of main motor / traction equipment. Obviously minor faults would be sorted as required.
Cheaper just to get correct number and ensure have stock of spares.
Because the Networkers are old trains, spares will be hard to come by. Therefore another reason to abandon certain units to keep the rest going.

There were unconfirmed rumours few months back that an award could happen this summer, but all gone quiet.
Steve White in February when asked stated "with a view to creating the business case for the Treasury and DfT this summer". That is the final step and once approved the various already agreed (by that point) contracts can be signed.
Of course there is a finite train building capacity depending on which company gets the contract. Scotrail were expected to award their EMU/BEMU order about May, Northern's order seems to now be early 2027. But in meantime have been massive rolling stock orders in Portugal, Berlin, etc and various European countries already in 2026. Ireland announced an Alstom order just before Christmas to replace all its original Dart trains too.
The ScotRail financing competition is still open for registrations of interest. If they've said May they probably meant 2027 or 2028, their expected dispatch of invitation to negotiate/tender is July this year.
Southeastern have offloaded 25x 465s and 27x 466s from the MetCam side, which is 154 carriages. 30x 707s brought in 150 carriages, then 13x 377s added another 52 carriages, so this gave SE an additional 48 carriages, equal to 12x 4-car units, vs their pre-covid fleet size.

The Electrostars/707s and Networkers have rather different availability targets. If the new fleet merely replaced Networkers vehicle for vehicle that would still be an increase on number of vehicles in traffic each day. While perceived as big changes looking at some of the existing gaps the additional running isn't as extensive as one might first expect in terms of extra mileage.

The December changes for Maidstone East reported so far can all be achieved by running existing electrostars around all day. The May extra Blackfriars services would require more units than before or changing formations somewhere to make it work.

Think of it like a car. If the engine's been smashed to bits somehow that'll obviously not run and needs reparation. In some cases repairs can be more expensive and/or financially burdening for the owner and so there's no use repairing it and off to scrap it goes. However if it's something less major like the check engine lights being on, that can be fixed easily, and in the context of railways, it should be done ASAP while maintaining safety, especially when SE needs all the stock they can get.

Of course the maintenance regime isn't 'allowing just certain units to deteriorate' on purpose. It's whether or not they can keep it from deteriorating. Take 465184 and 465005 as an example: 184 was stuck at Victoria shed for five months before it re-entered service whilst 005 had been sitting there for over a year and never carried passengers again.
Why could this have happened? The simple, common sense and possibly even naive answer is that 465005 had a bigger, more expensive problem than 465184. And considering both are more or less the same train from a basic point of view, anyone would obviously choose the cheaper option and fix 465184. Either way you'd get one train back in service.

The maintenance regime does not want to jeopardise the running of the railways, and when put together with the finite amount of money they have, sacrifices do have to be made. And such sacrifices might include stealing parts from a borked unit, like 465005!
