Honestly i really would not be surprised if the entire 458 project is cancelled and the whole lot of them are sent to the scrapyard just like what happened to the 442 trains a few years ago. Services on SWR have been massively reduced compared to before the Corona Virus so once all of the 701s are in service (if that ever even happens) then the 444s and 450s will probably be enough and the 458s will not be needed.

Not unless there are calls for increased frequencies in the future, in which case additional rolling stock will be required. I seriously doubt SWR would get away with the current timetable, but the question is, when will there be a time that frequencies will increase? If it comes in a few years, then SWR would only shoot themselves in the foot for scrapping rolling stock once again.

SWR is barely getting away with the current timetable now and what was really needed was implementation of the proposed Dec 2022 timetable.

It would be the DfT not SWR that would make any decision to send the 458s for scrap. The units are 23 years old and very non-standard. It must be quite an attractive proposition.

Non-standard is not a big problem if they stay at one depot, and that depot learns how to maintain them properly. It is even easier if you have a few spares (withdrawn units) that they own to strip parts from.

As for standardisation there are more 458 vehicles than 159s at Salisbury, so not the least standard train on SWR

Ultimately it will be financial, cost of lease and any upgrades/modifications vs cost of alternative fleets. This rule will apply whilst there is an excess of units, but if need more for a busier timetable then another rule (what is available) becomes the lead parameter in short term

If it is decided to retain all 458s then these could possibly get divided into 60-70% Cl 450 style with 3+2 for anywhere on non-diesel SWR tracks with 30-40% as dedicated pool of Cl 350 style with 2+2 for Portsmouth/Bournemouth workings?

Dividing a small subfleet into two even smaller subfleet a really doesn’t make sense.

I'll never understand as to why rolling stock would have to be cast aside because it is non-standard, as I get the impression reading from this thread. Non-standards shouldn't have the shunning it gets, and the 458s have proved that (supposedly) non-standard units can operate successfully because they have been able to work the Waterloo-Reading line to meet the fluctuating demand (Ascot Races, Twickenham Rugby, Reading Football), often alongside the 707s and 450s. They can also meet future needs as this has been the case with their upgrade to 5 coach units. If they can operate without a hitch on the Waterloo-Reading line, they won't have a problem elsewhere on the SWR network. Talk about a throw-away society in the UK!

All very well in a growing market, but where there is decline, ditching the non-standard stock is an obvious step. As has been pointed out, there is a huge surplus of 701s on order, because they were specified against very different passenger expectations.

Somewhere something would appear to need to drop out of the bottom, whether it is 458s at SWR because there is a surplus of 701s and 450s, or Networkers at Southeastern, because some of the 701 fleet is used to displace the worst examples of that fleet.

We could argue that binning 455s is symbolic of a throw-away society. It is only really an issue if we throw away and then have new build a few years later. If the long-term size of the rail fleet is smaller, throwing away the 458s is no issue.

By the time the 701s are all in service it is going to be at least two years or so - i.e. end of 2024/start of 2025. The Section 54 agreement on the 444s and 450s ends at that point and they will be more expensive to lease than the 458s. If anything is to leave the fleet (other than what is already planned) I would suggest it is going to be either 701s (to SouthEastern as part of Networker replacement) or 450s.

That is an interesting theory. Why are they only converting 28 of the 458s if there is the possibility of taking some 450s (or indeed 444s) out of the franchise?

I believe it’s 28 because in 12 car form it’s broadly equivalent in capacity to the originally planned 18 x 442. But that may not be what they really need now. But I also think the odds of any 444/450 going off lease are vanishingly small.

I would have to agree with your comment. Withdrawing the class 455 units, once the class 701 units have started in passenger service I think would in the short term be the case rather than being rid of the class 458 units.

Longer term, I can see whatever replaces the class 159/158 units also possibly replacing the class 458 units with possibly being a bi-mode units in some form with the ability to swap any diesel engines for battery units at a later date.

I have to agree with the speculation that if capacity increases are need, it’ll come from putting 701s on some Basingstoke and Alton workings to free up Desiro stock.

I would say the same. They are the mainstay of the fleet, and the thought of taking them off lease after years of reliable service and a recent refurbishment, just to be replaced by the troublesome 458s seems ludicrous. I can't see anyone wanting to lease them other than SWR either.

years of reliable service

Being a bit pedantic but fleet an availability looks at the minute is shocking. A quick browse on journey check shows lots of short forms. I was told recently 122 450s a day are required, leaving 3 for maintenance and 2 for repaint.

To be fair 122/127 doesn't leave many spare, 96% availability is very high.

They have an option on the remaining 8 458s - as part of the announcement about the 28 sets for the Portsmouth line it was stated that the remaining sets would be stored by Porterbrook as an option should SWR need it.

In terms of the leases, this, taken from SWR's DfT contract (https://assets.publishing.service.g...tr-south-western-trains-ltd-rail-contract.pdf) shows why I have said what I did. Note in particular the lease expiry dates. I am not saying it will happen, but it is an option should SWR not need all the capacity after full Aventra deployment.

Availability for the 450s is planned as 120/127
As was the contract between SWT and Siemens prior to 2017. This matched the long standing 95% availability, which even in my time (400 days) was the general rule. However on the 450 front this was generally pegged back to 118/127 (93%), without detriment to the peak train plan, on a booked diagram basis, as during those times numerous modification initiatives (eg: 450/5 conversion), and in some cases other issues, such as fallen tree damage (444037) were easily overcome with the additional buffer of individual 450 diagrams 119 & 120 being available to cover short falls, without interfering with the planned maintenance, cleaning etc, etc, that the seven units (diagrams 121-127) were required for under the contract.

I live in Farnham and would say that 10-701s would be very suitable as a replacement for any of the current services not diagrammed as 12-450, as these can be very busy indeed. I would miss the use of seatback tables, but this is compensated with the mini tables on the bays, which 450s currently lack. 10-701 would be a good increase in capacity on 8-450 (and 5-444)

I’ve just seen reports that the first two 458s will be ready Q1 of 2023, and will then be bedded in with the whole program still expected to proceed and be in traffic within 1 year, this was on an all staff video bulletin.

I wonder if they’ve considered using the eventual spare 701s instead of the 458s?
This would work by replacing the current 8 carriage 450 and 5 carriage 444s formations on the Alton - Waterloo - Basingstoke (semi) - Waterloo - Alton circuit with 10 carriage 701s, and then cascading the Desiros to the Portsmouth route.

I wonder if anyone on this forum ever considers that there are contracts in place that might stop “fantasy fleets” happening?

Didn't stop the 442s going for scrap part-way through the retractioning contract.

Yes, but I suspect that given the age of the vehicles and the complications of the retractioning exercise, that Angel and SWR would have settled.
