As of today, after the AM peak it looks like Reading services are down to just 1 pair of 458s, with 2 pairs of 450s and 4 pairs of 455s.

If journeycheck is to be believed then that arrangement could be for today only with a pair of 455s vice a pair of 458s

05:50 London Waterloo to Reading due 07:11
07:39 Reading to London Waterloo due 09:07
09:20 London Waterloo to Reading due 10:43
11:09 Reading to London Waterloo due 12:35
12:50 London Waterloo to Reading due 14:13
14:39 Reading to London Waterloo due 16:07
16:20 London Waterloo to Reading due 17:42
18:09 Reading to London Waterloo due 19:34
19:50 London Waterloo to Reading due 21:13
21:39 Reading to London Waterloo due 23:07
23:30 London Waterloo to Kingston due 00:15
Will be formed of 8 coaches instead of 10.

This diagram only reverted from 2*455 back to 2*458 last week, and these temporary changes have a habit of becoming permanent so you may be correct.

Looking at Journey Check it says for some services that
Disabled toilet facilities are reduced.

Will that solely be on the 458 and 450 services or will it be or include the 455 services which have no loos at all?

You have just answers by question.

It seems when they switch to use a 455, they report if different aml my of coaches are used but don't told tell you that there will be no toilets on board.

Would they make extra allowances for this with a stop somewhere on route?

Not from my experience. If the diagrammed train has no toilets then there's nothing to be reduced.

Anyway, the info I got is from RTT, not Journey Check.

That diagram is booked 455 in the long term plan, but 458 in the short term plan this week, and I assume last. So yes, it is likely to become permanent at some point.

At least all the diagrams are 8 car, they seem to have sorted out the shortform problem on the Readings, at least for now
Let's not forget the evening 455 diagram though, which would increase the total number of 455s on the line to 5

Yes, from the unlimited supply of 455s that SWR seem to have!

Indeed. This mornings peak is the first that SWR have had 70 455s in passenger use from the fleet of 80(+2). SWR must be about hitting the buffer stops of how many 458 diagrams can be absorbed by the 40 year old 455s.

I’m hearing that the 458/4s now have a whole range of route and gauge restrictions and must only go on the dedicated diagrams that will be created for them. I don’t know if it’s just a paperwork exercise or whether something substantial has changed with the physics of the units. It would explain why the moves to and from Wembley run as X-paths yet the C4 move (5B39) runs without any such restrictions. The moves of the barrier coaches run as Q-paths which suggest the out of gauge vehicles are the 458/4 themselves.

I was thinking more from trains being switched from diagrams with loos to those without but I realise now that in this case it is trains without loos going to ones with loos. I.E. 455s to 458s.

And maybe building up to tell the world how it makes it all too difficult to introduce the 458/4s in the short term to cover for the lack of 701s. How very convenient!

The 458/4s will only go on a series of set diagrams on Weybridge and Windsor services, they won’t be able to do mainline suburban or Readings from what I understand.

At the risk of asking a stupid question... why?

They are going back to 4 car units (that's progress for you), they haven't received any significant ride height modifications or anything AFAIK, so what is the problem?

Yes, because 12 carriages is more capacious than 10…

The only thing I can see is that the yaw dampers have been refitted as maximum speed is back to 100mph. But they were present on the 458/0s.

I don’t know I’m afraid, like I said earlier it could just be paperwork that’s yet to be filed, or the works could have affected their kinetic envelope or it could be a mixture of the two.

Very good plenty of life left in them yet and pretty prescient of Stagecoach to retraction them

These units are now (apparently) replacing 10 carriage trains on Weybridge and Windsor services. There won't be any 12 carriage formations.
Which is down to the failed introduction of 701s, meaning these trains, converted with the original intent to operate as 12 carriages on mainline services, are deputising as a stopgap.

Even though in previous 4 car format they were literally the only units on Reading services for several years.

So 458422 is on its way back south (I'd missed this one going north :lol: )

My records have 458520 & 458528 as being at Widnes still - is this still the case please?

458420 was released from conversion on 26 February. 458428 came out on 7 November last year.

458521 is the only set at Widnes currently, until 501 comes north to join it.

458428 was delivered to SWR 07.11.23 and I believe is now stored at Eastleigh
458420 was delivered to SWR 27.02.24

458521/421 is the only one at Widnes tonight
