But I have seen quite a few services using 466+465+465 this year, enough to make me believe South Eastern cannot cover all 10car diagrams with 376 and 707s. There are 30 class 707s which are new arrivals (making up 15 10car trains) so that would theoretically allow removal of 15 class 466s AND 30 class 465s assuming no service changes.
You also get 2 out of 5 Tunbridge Wells' allocations as 10-car Networkers (the other 3 being 8-car) Mon-Thu. 707s are not cleared to Tunbridge Wells, and I'm guessing 376s are not either. The two 10-car are allocated to the 17:26 and 17:56 departures from Charing X, which are rammed to Orpington, so goodness knows how bad they are if those extra 2 coaches are not there.

You have a point there, however I believe Tunbridge Wells services are eventually going to be 12 car 377s once they arrive. (Tunbridge Wells and Ashford are the main lines 377s will run on, I think).

Even then - if you are able to make 3 8-car trains per hour instead of 2 10-car trains (due to more 465s being freed up from mainline routes), it could work.

377 formations are restricted to 8 cars at Tunbridge Wells because 12 cars won't fit in the siding

I heard they are going onto the Gillingham and Ashford ones, not Tunbridge Wells due to the need for some 10-cars on the latter and their stabling locations not being Electrostar dominant. Unless SE have changed this.

Either way, 13x 4-car 377s is going to struggle to replace Tunbridge Wells and Ashford, as the former will need a minimum of 10, while the latter needs a minimum of 3-4. Gillingham services however only require 7 units to directly replace the current Networker provision, as a couple of 8-car 375/377 diagrams already exist. So the latter total would be 10-11, allowing 2 for maintenance/resilience.

377 formations are restricted to 8 cars at Tunbridge Wells because 12 cars won't fit in the siding
Technically trains don't have to turn round in the siding, but most of them do so yes that'll be an issue.

There’s been posters up at Tunbridge wells and high brooms stations, official ones from southeastern, saying “new trains coming soon” with pics of 377s. So they are, or were, planned for Tunbridge wells services

It was originally mentioned as including Tunbridge Wells line alongside Maidstone East, more recent output has focused on Maidstone East only. It's possible that was a communication mixup rather than intended, replacing 10-car Networkers always seemed a weird use of 377s.

SE need the extra 377s. Really.

Their existing electrostars are getting a lot worse. How do I know? Well, when I've looked around on their website, both today and yesterday (and also a couple days before yesterday), several Ashford and Gillingham services were short formed at 4 cars from 8. I know this is not the fault of 465s/466s as they are 6 car max down to Ashford, and the Gillingham diagrams were labeled as 377 on their FOI page. I bet that was cozy - trains are crowded enough as an 8 car let alone a 4...

Anyone know what's happening with SE's existing electrostars? They didn't used to have so many issues.

SE is getting the 377s from Southern as they are going to be replacing the networkers that run to Kent, and the networkers are only going to be doing the metro routes before the new trains are in customer service at the earliest October 2027. I am guessing that after that, the 377s will be going back to Southern railway including the 377/5s.

Nothing suggests that will happen. The 377s moving to Southeastern would appear to be all about reducing the size of the order needed for Networker replacement and ensuring it can be a 'proper metro train'.

There are certain routes though that could do with stock that has a comfy interior and high acceleration. These include Gillingham stoppers from Victoria, the Medway valley and Sheerness branches, and even the Maidstone East line services that are all stations Otford-Ashford. If the new Metro fleet to be ordered has a 90-100mph top speed across all units, all that would be needed is to refurbish a portion of them to do these longer but frequent calling point services, similar to how the 465/9s got put on these routes with a refurbed interior. 375s and 377s do not accelerate very well at low speeds, so are not as optimal for high calling patterns.

Official announcement from Southeastern

Here are the relevant bits for this thread:
  1. Sole Street line: London to the Medway towns, Sittingbourne, Sheerness, Faversham, Ramsgate, Canterbury East and Dover


Longer trains to increase capacity

  • The 05.46 Dover Priory to London Victoria and the 17.10 London Victoria to Dover Priory will be 12 carriages rather than eight.
  • The 07.02 Ramsgate to Cannon Street will be 12 carriages rather than eight.
  • The 06.45 Gillingham to London Victoria and the 18.12 London Victoria to Gillingham will be eight carriages rather than six.
3a Maidstone East line: London to Ashford International via Maidstone East

  • Eight more of the Class 377 Electrostars with air-conditioning and charging points are being introduced to replace the older Networker trains.
  • There will be additional trains for stations between Ashford International and Maidstone East to London Charing Cross.
  1. Hastings line: London and Sevenoaks to Tonbridge, Tunbridge Wells, Battle and Hastings
Longer trains to increase capacity

  • The 18.45 Charing Cross to Hastings (as far as Tunbridge Wells) service will be 12-carriages rather than eight.
  • All semi-fast services that run between Charing Cross and Tunbridge Wells will be lengthened to 10-carriages.

How do you know? I did a freedom of information request with SE railway and the reply I got is that they are going to order from 350 to 640 new carriages. So, even those, I am just guessing on my part. What is the evidence that suggest that will happen?

I don't. We are both guessing.

My suggestion in this speculation is that Southeastern, by taking in the extra 377s, will have a combined fleet of 375s and 377s which is right sized for its non-Metro operations for the next 15 to 20 years.

Your suggestion is that some additional rolling stock is ordered as part of the Networker replacement exercise which enables the 377s to go back to Southern in a few year's time once freed up.

It is quite possible that the Networker replacement fleet size could be quite tight if availability of finance is limited.

I did a freedom of information request with SE railway and the reply I got is that they are going to order from 350 to 640 new carriages.
350 carriages wouldn't be enough to directly replace the 388 BREL 465s carriages. We don't know what the 640 is designed to replace. There must be more than one permutation at play.

However, at the current time, the cascade is about increasing the size of the 377 fleet at Southeastern to a level which was first talked about in 2016.

Confirming that Tunbridge Wells' will remain Networker-dominated, with the all 10-car uplift being welcome and needed (there are definitely not enough 3-car 375s to form 5x 10 carriage trains and maintain the branch line workings). If 8/13 additional 377s are going to the Maidstone East line, this suggests the Gillingham stopper route won't be all Electrostar as I don't think 5 will be enough, particularly if not all 13 are used daily (looking at the summary I'm willing to bet the 06:45 and 18:12 services will be ones becoming 377 that are not currently).

It’s got to be at least a possibility. Presumably the size of the new fleet will depend on (i) what the train builders offer in terms of overall cost, and (ii) what the treasury is prepared to pay.

But if Networkers can be displaced off the outer-suburban routes (for which they were never built for anyway) then it increases the likelihood that it might be possible to procure a common fleet to replace all three metro fleets, which for the long-run is what SE ideally needs.

In any case, why would SE want to procure a metro fleet and then have to have a variation of it to suit outer-suburban runs where seating capacity is more valuable?

Do the 376s and especially the 707s really need to be replaced in the long term?

Absolutely they don’t *need* replacement. However I’m sure SE will at least be looking at options to standardise the metro fleet, even if it ends up not happening.
It would be a daft situation if SE then went another 20 years operating 3 types of metro trains, the 376s, 707s and "2027 stock", before in 2047 then replacing just the 376s and 707s with a new train, that operates alongside the 2027 stock!

But I can't see where the 376s AND 707s could go.

(I'll get my coat).

But yes, maybe 376s & 707s to bolster Southern as they have no "metro" units now their 455s have gone ?. There is not much choice really unless the 376s can gain panto-graphs or 707s (which can work with panto-graphs).

But we need to get away from big bang fleet replacements creating a boom and bust cycle for the train builders. So maybe it is prudent to replace one third of the SE metro fleet at a time ?.
Look how the mass roll out of 701s is going (currently down to a training log jam).

I do imagine a major issue is that the various types are so different, rather than variations of Mk1 EMUs or variations of Electrostars.

I can imagine Southern benefiting from one of the 376s and 707s, but they wouldn't need both. The 376s are cousins of their 377s, the 707s are even more similar to the Thameslink 700s.

I was more talking about their recent reliability issues. Sorry, I should have made that clearer.
I've definitely noticed more 4 cars over the past few weeks/months, and looking up SE's formation updates some days confirms it is not intentional and is due to faults with the trains.

Today, multiple 377s on Gillingham-Victoria are short formed at 4 from 8 today due to train faults, including during the rush hour. This is the case too often.

SE should really be worried about ironing out the issues with the existing 375/377 before they take on anything new, in my opinion. If they're already struggling to maintain the current fleet, adding more to maintain will just place a strain on their resources.

I could see this being an issue on their main line services - unlike the 465/466, the 375/377 will be around for a long while yet, and reliability issues only tend to get worse as trains age.

We can only hope SE find a way to fix them.

All of this surprises me - I knew the 465 (especially the BREL units) had a reputation for being unreliable, but the 375/377 have a reputation for being rather sturdy, so I'm not sure where these issues have come from.

I am not 100% sure but are the SE 377s not maintained by Selhurst despite changing operators ?.
That suggests Selhurst might be getting overloaded despite losing all their 455s !.

The short forms were formed of Networkers, not Electrostars.

On the diagram page, I checked, and all the services short formed except for the 21:15 to Victoria were diagrammed as 377s, so any Networkers on those runs were substitutes. The Ramsgate service was a 375.

Either way, this has been an issue for a number of weeks, and can often be seen affecting Ashford services, which frequently get short formed down to 4 from 8 coaches. It happens so often that one of my friends has seen Ashford commuters complaining on Facebook. These are definitely 375/377, as Networkers never run as an 8 car down to Ashford.

I take your point - while short forms definitely can still affect 465/466, they seem to really be affecting 375/377 right now, and severely. I'm unsure why, as they used to be so reliable. I find it hard to believe it is just aging as the deterioration is too sudden for that.

I am not 100% sure but are the SE 377s not maintained by Selhurst despite changing operators ?.

I'm not sure either.

Are all the units Southern and Southeastern due to be getting moving in May, or will it be more staggered?
The cascade needs 379s to be introduced into service, which isn't all by May.

Southeastern is meant to get its 13 units by December, as noted in message 21.

This is a bit OT but I suspect the knowledge exists in this thread's contributors:

Having now seen a few 387/1s running the West Coastway (e.g. 1N27 Southampton Brighton), I noticed their first class accommodation is at the inboard end of their DMC. On the 377 four car sets, first class is at the outer end of the DMCs

I know the 387/1 first class area is larger - but why locate it at the inboard end of the DMC? Surely that creates more risk of standard class people walking through it, from the DMC's outer end to the toilet?

It is correct that Bombardier designed the units this way. This setup has caused issues on GN for exactly the reasons you describe.

I have a suspicion that it’s a fallback from the 5-car units, which originally had first at the outer end, taking up over half of the driving car, as is also the case on the 379s. Somewhere along the line this seems to have been deemed too much for a 4-car, so rather than change the design it was just swapped round, which at some point was retrospectively applied to the 5-cars as well.
