SWR Class 458/4s: fleet status and withdrawal updates

Rumour at the depots is that the 458/4 will be history by July. Seems a bit soon but that's the latest.
Given that SWR hope to get 55 701s diagrammed by "late summer" (currently 39 diagrams ) and if SWR decide to displace the 458s before sending the 450s to strengthen mainline services (the latter of which was the plan at least until a month or so ago) then that would seem feasible.

Waterloo to Reading, Windsor, Weybridge and Hounslow loop.
What routes are the 458s on? Never been on one so would be good to try one before they go!
Worth noting that they can only get to Weybridge via Staines and Chertsey in passenger service.

On Sundays they also work Woking to Waterloo via Chertsey, Staines and Hounslow (and indeed Saturdays too if, like the last two weekends, mainline trains have also diverted via that route).

The externally published target is 50 701 diagrams. The number of required 701 diagrams to cover the 458s with the mainline strengthening in the current timetable long term plans is 52. That includes a stabled pair of 450s at Wimbledon Park meaning 51 would probably do. I'd expect the internal goal is more ambitious than the external one. If after this week a new 701 diagram is added each week that would hit 52 at the end of June. (Edited to reduce required counts by 1)

On a more positive note for the 458/4s, Friday was the first time in a month that hit the availability target with 22 all out at once. Today might not have had any substitutions either but harder to tell as some of the diagrams are altered due to the engineering work at the weekend.

Thanks. When I last quoted 50 I was "corrected" and told it was 55!

So if 53 701s are required to cater for 450 mainline strengthening and getting shot of the 458/4s that sounds comfortably achievable by the end of the summer. Bad news then for the 458/4s - and the 701/5s.

The 50 is from the bottom of this press release. That figure is probably a pessimistic scenario on the basis of 701/5s not being ready and some 701/0s needing serious work to get into service.

Revisiting the numbers realised I counted 12 not 11 458/4 diagrams in the plan so the required number is actually 52 or 51 if the stabled pair of 450s at Wimbledon Park replace a pair of 458/4s. The 701/5s are a separate conversation, while not needed immediately, they increase peak passenger capacity at little additional cost (as rolled into the 701/0 contract) and allows service expansion or strengthening which will happen at some point.

No idea if we will get a new 701 diagram in Easter week. But on the basis of what’s set out above can we now assume that all new 701 diagrams over the coming months will displace 458/4s until they’re all gone?

MD of SWR has said that retirement of these units will begin shortly.

Modern Railways is the source

I guess they need the depot space with the remaining 701s slowly but surely arriving.

Such a waste of money. Just like the refurb of the 442’s. Though I think Covid was also a bit of a nail in that coffin.

Given the 458 refurb was a replacement of the 442s after their pointless refurb, I don't hold much hope for what technically replaces the 458s.

Last Sunday they also reached Kingston on a shuttle to Barnes. (Maintenance work in the Putney area was preventing a completen loop service working, and the Windsor and Reading srevics were diverted via Wimbledon) Unlike the 701s, they fit in the bay at Kingston.

That's the thing. Passenger numbers haven't recovered and probably never will within the remaining useful life of the 458s. Plus they're non-standard and troublesome so if anything is surplus to requirements it's them.

It's a moot point between 458/4s, 442s and 769/9s as to which had the most amount of money wasted on a completely pointless rebuild. The 458/4s possibly score extra points for the rebuild actually making them less suitable for the work they've done since, and for management apparently not understanding that they couldn't be used for the work they were intended to move to.

Passenger numbers are kept down by SWR still running a half-baked Covid "emergency" timetable. Either the missing trains should be reinstated, or the timetable rewritten to suit the reduced numbers of services (and thereby wiping out most or all of the improvements that SWT eventually achieved).

We are getting to the point now with no TOC franchises, where short term leases will be replaced by longer term leases.
Porterbrook now will have several units, like the 350s and 485s, with say 10 years potential life left, in storage.
I expect Porterbrook would like to see the problems using the 458s on the PDL overcome and batteries retrofitted to the 350s?
Now wondering into speculation territory as to whether roles can be found for them or do they just get scrapped?

At least 20 years for 350/2, I’d have thought, going by the expected 35-40 yr life of a modern EMU.
(Drifting off-topic however.)

As has been said countless times, the physical space on the ground at both ends of the route (let alone the astronomical costs that would ensue to modify same) prevent meaningful adjustments being made to provide adequate resilience within the overall plan, including, critically, during disruption, particularly if infrastructure failure at either terminal is the route cause of said problems. The cost of such alterations is beyond reason, given the current Desiro fleet can cover the service more than adequately in both fleet size and infrastructure usage flexibility.

Just for point of reference, the cost of the Class 458 refurb was covered by the RoSCo with higher leasing charged in return. So a big tactical shot in the foot for Porterbrook

The bigger question perhaps is who proposed/sanctioned the refurb on either ill founded information or purely on an assumption, that 12 car 458 would work?

It definitely wouldn't have been ill founded at the time. The problem was Covid and after covid just remove all incentive of completing the 458 Portsmouth program, the delayed 701 introduction also contributed in adding to that too as the 458s were more suitable than the Desiro and 455 on the windsor side routes. The question really would be how long would 458s stay on portsmouth routes had the plans gone through and then the 701s still been introduced, displacing the several desiros that served on those routes.

I'd like to know this..is it another blot on the First/ MTR copybook or some genius pen pusher at the DfT?

I can't imagine a civil servant being the person who would have signed off that there were no platform length / signal sighting issues....

Would surely have been a combination of SWR and NR.

You do wonder on NR involvement - presumably they would have needed to know the exact train length before saying yes or no, so we're they even consulted or were they given incorrect info?

They’re only “troublesome” because SWR see them in that way. SWT didn’t have the same attitude problem back in the day…
