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

[Peter Sarf]

Having to, is probably not strictly correct.

If they are leasing them anyway, then they are choosing (rather than having to) not to use them and store them. In theory whilst they are on the books and available, they could keep using them and transfer the 450s to mainline work, or if they don't have crowded services that need strengthening store some 450s instead.

All plausible / reasonable.

At the moment SWR appear to be leasing, but not using about 220 coaches (170 class 701, and around 50 class 458). There is element of standardisation (and shoddy service ready condition of 701/5 so can't yet be used) but there is a financial cost of having this stock. And which is least worst cost, to store or return. There has been no takers to sub-lease them to another operator either.

Yes. I doubt the ROSCo for the 458/4s have an easy alternative use for the 458s.
(worse still for the 458/5s which are now definitely a "micro fleet").

I am not clear if a 458 or a 450 is cheaper to operate, both require maintenance at mileage intervals, but which is cheaper to use over next 12 months until lease expires is not obvious.

I remember way back it was said that the Desirios were expensive to lease (and buy) generally. I have always believed you get what you pay for and Siemens products do seem to be good quality. So I would assume 458/4s are most likely cheaper to lease than 450s. I also remember it was said that SWT (Stagecoach) were ending up paying extra for a higher availability of 450s to cover planned extra uses. There was a clause in the lease of 450s that allowed for above expected/agreed/contracted use (logical as Northam depot would have to work harder to attain higher availability / miles). How true this all is I cannot now be sure as I don't recall the source (probably Modern Railways).

I assume that could be logical for most leases with of course penalties if the original service level was not reached.

So I have always had at the back of my mind that SWR would desire to ease of on the 450s intensive use. Obviously Covid reduced that pressure so the 442s went and now the 458/4s (but is the idea that the 458/4s are going merely an assumption we are making). While 701s become standard on suburban duties.

Conjecture territory :-
You have made me think. These 458s could be a bargaining chip to get a better deal on 450 leases. If the allegedly high basic lease on 450s could be reduced that would be sensible. If not then does a small (not quite "micro") fleet of 458s become cheaper and we see a dozen or so 450s handed back to the ROSCO.

It might even be as simple as trying to free up maintenance space at Wimbledon so they can take on remaining 701s, whereas 450s are Northam's responsibility

On maintenance space I think Bournemouth is said to be the home for the 458s. But I am a bit puzzled as that is far from suburban land, but then the 458/4s were supposed to be batting up and down the Portsmouth direct by now !.
(certainly is home for the out of use 458/4s !).

There was a clause in the lease of 450s that allowed for above expected/agreed/contracted use (logical as Northam depot would have to work harder to attain higher availability / miles)

Can't comment on actual financial penalties paid out (if ever?), but for many years the Desiro's base plan diagrams kept mileage to within specific levels on an annual by unit basis to prevent hefty financial penalties resulting from breaching those contracts.
In addition both planned weekend engineering work, and Control VSTP changes, were required to take account of this, and on the approach to the end of each (Siemens) financial year, extra effort was put in to planning STP processes to ensure the agreed limits were not exceeded in the last couple of months of any given period.

It is my understanding that when FG/SWR took over the franchise, these (mileage) restrictions were done away with, but that comes second hand to me, so I don't know the detail.

On maintenance space I think Bournemouth is said to be the home for the 458s

That was the plan (with use on PDL etc - apparently?), but in truth I doubt it ever really got off the ground, but that is just an educated guess. The trip workings to/from Bournemouth may have been exam related, although from what I have seen on here they seem to have largely ceased now? Suspect Wimbledon are now doing whatever needs to be done until the axe finally falls.

How many 458s are still seemingly in the 'running pool'?

8. Full list in the first post on this thread.

Are there still two 458/5's at Wimbledon? Thought i caught a glimpse of them last week but I understood they were all off lease now, in which case I wonder why they are still there given space is apparently at a premium?

I saw them there on Friday

Yes, I could see both from the main line on Saturday... they're behind the East Wimbledon shed, outside, against the buffer stops.

Three pairs of 458/4 allocated to passenger services vice 701 today (Tuesday 18.08.26). All three are on Windsor diagrams although a chunk of the 2U10 diagram is missing from journeycheck for some reason.

Many thanks for this, I wonder whether the 458s will still be in service in September?

I initially thought that posting a list of 458s working vice 701 would be for a few days to document their final workings for SWR, but it does seem to have become a semi permanent arrangement.

Three pairs of 458/4 allocated to passenger services vice 701 today (Wednesday 19.08.26).

The allocation data passed to RTT for this last pair shows them to continue with the diagram working 2H93 1743 London Waterloo to Shepperton which they won't because the return 2H60 1836 Shepperton to London Waterloo is via the mainline.
