I’ve heard that the 458s have not been approved for 12 car running due to concerns on the signal sighting due to the long corridor nose. This could be nonsense, or it could be another nail in the 458 project.
If this is true and they are not permitted to work as 12 cars, so why have they been returned to their previous guise and to 100mph status when there are obviously now no plans to put them on the PDML, and just wasted money when they could have simply done an internal refresh and repaint and left them as 5-car units, able to work as 10-cars, as they have done since 2014

This has been answered several times on this thread, but obviously not expecting you to trawl back through 3000 posts.

The 458s were originally going to be withdrawn completely, being replaced by 701s. However, the 442s, which had been reinstated to work on the PDL, proved to be problematic and the solution was to withdraw them and replace them with 4-coach regeared 458s running in 12 coach formations instead. The 458s could not run faster than 75 mph as 5 car units so 10 car formations were out of the question.

Move forward to the current day and SWR / DfT appear to have concluded that the 458s are not required after all, presumably because of a lack of the predicted passenger growth. Add in the continued non-appearance of the 701s and we have the complete mess that is the current SWR rolling stock situation.

Also worth mentioning (unconfirmed) - that the 458s needed to be returned in the state they were delivered by the lessor? I.e. four car units, geared etc. Again, Alstom did do the work but you never know about devil being in the detail - Alston being paid for the work to extend to /5 but reminding them when they get returned they need to be in the condition delivered.

Alstom don’t own the units…

Just passed 5Q95 Wimbledon Park depot to Woking and back. Operated by a 458/4 but don't ask me which unit!
5Q95 and 5Q97 in RTT today, but not activated.

5Q51 1114 London Waterloo to Staines Up Loop has been activated, but presume will be a 701 test and not a 458/4 test?

The 458/5 and 458/4 modification programmes were done by owner Porterbrook after they had agreed contracts for the revised fleets with SWT/SWR/DfT. As such new leases were signed to reflect this.

I’ve no idea where you have got the idea from that they needed to re-formed for handback from.

IIRC Porterbrook proposed the 458/5 project as a way to make use of the Class 460 units.
I can only think the rumour stemmed from the fact that, had the units been returned to Porterbrook, their 75 mph limit would have hampered finding new homes. The only way to return them to 100 mph is indeed to remove a coach.

It was part of SWT's Grand Plan to make a fully 10-car railway - the fact that the class 460 vehicles were available was a way of acheiving this. The plan also involved leasing the 456s (to work with the 455s) and the new class 707s. The retractioning of the 455s was part of this, intended to reduce maintenance, thereby freeing up workshop capacity for the larger fleet. So was the extension of many platforms on the network, notably at Waterloo 1-4 (previously only platform 5 on the suburban side could take a ten-car train).

Then First Group came along with their shiny-shiny all-new proposal to get rid of the existing fleet. Well, the "getting rid" part is going well, at least - the 456s, half the 458/5s, and all but two of the 707s have gone, along with a few 455s. Also gone are the Hounslow roundabout services, now truncated to Twickenham, to the detriment of St Margarets, North Sheen and Mortlake in particular, who now have only 2tph calling.

These were mandated service cuts by the DfT which would have happened regardless of owning group.

Thank you my friend, really appreciate that someone knows what was what back then. For further clarity part of the reason there were still 3 x 8-450 diagrams on the Readings and a number of 8 car 455s still bouncing around at the end of said project, was that the order for 707's (which was 30 units/27 traffic) in the event, was the least expensive for 'The Department'. Plans for 36 and 40 x 707 were also submitted......I will say no more!

The 460 vehicles were part of the plan to get the first 5 car 458's up and running, before any of the existing diagrams (at that point) had to be reduced to 5 car to allow the rebuild cascade to work. IIRC there were four x 458/5 (essentially ex 460 vehicles) up and running before the first of the original 458/0's had to to be removed from service for the rebuild. The idea being that the whole plan could be delivered without any service train formation reductions.

Indeed. And imagine the chaos if those services were still running with SWR's rolling stock shortage.

Does SWR even have a rolling stock shortage ?

Did some crunching of ORR data Jan-Mar and compared it to 5 years ago (2019) pre pandemic

table 1243 : train km in 2019 was 9.9m, 2024 is 8.5m (down 14.1%)
table 1253 : vehicle km 2019 was 74.37m, 2024 is 62.47m (down 16%)
so trains have been shortened from average 7.51 carriages to 7.35

On passenger side
table 1223 : journeys, in 2019 was 55.1m 2024 is 38.7m (down 29.7%)
table 1233 : journey km, in 2019 was 1495m, 2024 is 1276m (down 24.6%)
average journey length was 27.15km, 2024 is 29.12km, so passengers travelling 7% further than 2019

Clearly if passenger km down 24.6% but train km is only down 16% (compared to 5 years ago) then could argue not shortage of stock. Alternatively could say if there is a shortage now, then there was bigger shortage 5 years ago.

On other hand if journey length has grown 7% could they need more trains suitable for longer journeys, and fewer short distance stock.

(all data from ORR spreadsheets, for SWR)

Crushed into a sweltering 4 car 455 at 17.10 from Wimbledon to Epsom yesterday, it definitely felt like there is a stock shortage. This service should be 8 and ideally 10 cars.
(I respect the statistics though, but an overall picture masks some of the specific problems).

Well of course it does.

The fatal flaw in your argument is that you're assuming that all trains have the same constant load factor and that passengers journeys and km have decreased proportionally on each train across the week with the reduction in train length and service frequency, and that train lengths can be constantly adjusted by one coach at a time.

Try telling people crammed into an 8 car train on a half-hourly frequency in the AM peak on a Wednesday that there is no rolling stock shortage, when they previously had 10 car train every 15 minutes. Or those on the 4-car 1633 Waterloo to Windsor (used to be 10 car).

It's obvious that some trains need to be longer and that there need to be additional services reintroduced, but SWR doesn't have enough trains to do so and barely has enough to keep the current service levels going. Hence why some 458/4s are being brought into use temporarily.

I think the main problem appearing now is that the revenue will not match the demand. Seems to me off peak is incredibly busy on many of my journeys. So without the season ticket revenue the railways can afford even less capacity per passenger-km that they could before Covid. Could this lead to a dilution of the difference between peak and off peak fares now that many commuters seem to be allowed to come and go on days and times that suit them ?.

With South Western seemingly losing an above average number of peak hour commuters maybe SWRs predicament is worse than for other commuter TOCs.

Would anybody have the slightest idea to whether during the refurbishment, the units received new PIS indicators internally and externally and have additional LCD TV Style displays at the end of the coaches akin to the GN Class 387s? Have their rather piercing door chimes been replaced with your typical RVAR chimes? Akin to Classes 455, 321, 317?
Also is it still anticipated for a certain number of refurbished units to enter service to Weybridge from this month? Or could we start seeing them complete longer distance diagrams alongside the Class 450s to destinations such as Alton and Basingstoke? Or for now will be they be concentrated on suburban services?

No changes to PIS or door chimes. They are only cleared to operate from Waterloo to Weybridge via Hounslow and there's no plans for them to run on longer distance routes. They're only being used as a stopgap to cover for the continuing unavailable 701s, and because of the 458/5s being withdrawn for the refurbishment project itself.

I'm surprised the PIS is even still compliant with current standards. It's a 30 year old design conceived before GPS came into general use. Stations can't be edited in or out in the event of disruption or engineering alterations. The system has to be switched off instead. Plus, on the 50% of occasions it's actually working it seems incredibly flaky, being based on wheel revolutions and gets out of sequence frequently.

Indeed, original PIS, Door Chimes and Toilets remain. This has been a carpet and new seats job, sadly not extending above the heater covers or dado rails. Even a lot of the cab stickers so far remain unchanged.

It’s a shame that PA system hasn’t been replaced yet, even with something as naff as Train FX. It didn’t take the PA system long to spin out of rotation due to wheel slip on the Reading line and you could often now be arriving into Reading when your actually leaving Wokingham, Winnersh or Earley.

Are they at least changing the PIS voice even if they are keeping the same PIS system? I know on the 158 159 444 450 455 they have very recently swapped Celia Drummond to Elinor Hamilton so i presume they will do the same with these? Although i would be happy if they kept the same voice. The old announcements sound a lot better.

It's probably just as well they aren't having a more thorough refurbishment given it appears there's no long-term use for these trains.

458s don’t have the axion system present on the other stock, so likely to be Celia announcements still

That is a good point. Maybe on the Axion system it is a simpler procedure than the Alsthom system. Although they did change the PIS from the Unknown Male to Celia Drummond during the 458/0 to 458/5 project. So it seems like changing the voice from Celia Drummond to Elinor Hamilton is possible if they wish to do it for the 458/5 to 458/4 project.

But i would certainly be happy if they kept the Celia Drummond announcements. The announcements on the 458s do have weird popping noises and incorrect inflections and are not as good as the Axion version but overall they still sound quite good and clear.

I also note the 701s have not had the voice changed either. I am not sure what system the 701s use but i think it is something different to any other SWR stock.

Unknown Male also known as Juniper Man. There was something vaguely sinister about his voice. :lol:
