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

[Siemens Staines]

On Thursday it looks like there could possibly be a planned swap of 458(s) in store at Strawberry Hill?

5Q97 1046 Strawberry Hill C.S.D. to Wimbledon Park Depot Sdgs
https://www.realtimetrains.co.uk/service/gb-nr:Q53406/2026-09-17/detailed
5Q98 1315 Wimbledon Park Depot Sdgs to Strawberry Hill C.S.D.
https://www.realtimetrains.co.uk/service/gb-nr:Q53407/2026-09-17/detailed

5Q97 has departed with 458414 and 5Q98 is allocated 458428.

Whether or not 458414 returns to passenger service remains to be seen.

Whether or not 458414 returns to passenger service remains to be seen.

Would I be right in thinking the 458/4s stored at Strawberry Hill are more likely to see action again than those way down in Bournemouth ?.

Also am l right to assume some rotation of 458/4s is likely so as to keep them healthy but also will have to happen if any in service have reached their deadline for a service/overhaul ?. (assuming here that SWR are not going to spend on unnecessary work).

One pair of 458/4 is allocated to passenger services today which is shown as vice 701 on journeycheck (Friday 18.09.26).

Three pairs of 458/4 are allocated to passenger services today, one of which is shown as vice 701 on journeycheck (Monday 21.09.26). This includes 458414 which is the first return to passenger service of a unit which had been in warm store.

458414 + 458415

The other two pairs are not shown as short-formed, so I assume are the aforementioned new booked diagrams for the class which were booked 2*450 until last week.

458402 + 458404
2C09 0618 London Waterloo to Reading
2C20 0809 Reading to London Waterloo
2C23 0948 London Waterloo to Reading
2C34 1139 Reading to London Waterloo
2S37 1322 London Waterloo to Weybridge
2S46 1503 Weybridge to London Waterloo
2V47 1637 London Waterloo to London Waterloo
2R53 1815 London Waterloo to London Waterloo
2S65 2022 London Waterloo to Weybridge
2S74 2203 Weybridge to London Waterloo

458412 + 458423
2Y03 0506 Clapham Junction to Weybridge
1S12 0632 Weybridge to London Waterloo
2V13 0807 London Waterloo to London Waterloo

Obviously there will be an evening peak leg to the 2Y03 diagram.

 

[SECR 65]

Will more pairs be needed in the 'short-term servicable pool' if there are now two booked diagrams plus the existing 1-2+ units of 701 cover?

 

[Siemens Staines]

Obviously there will be an evening peak leg to the 2Y03 diagram.

Well obviously I was wrong. The 458s worked in the morning peak only and a fresh pair of 450s off Wimbledon worked in the evening peak only. The 2C09 diagram that was 2*458 yesterday, is 2*450 today. It is possible that both diagrams yesterday, that I thought are booked 2*458, are in fact still booked 2*450? I am confused.

Two pairs of 458/4 are allocated to passenger services, one of which is shown as vice 701 on journeycheck today (Tuesday 22.09.26). 2Y03 may or may not be vice 2*450.

458414 + 458415
06:54 Windsor & Eton Riverside to London Waterloo due 07:54

Thank you. Do you know if the diagram starting 2Y03 is supposed to come out again in the evening peak, or is it a morning peak only diagram.

Is anyone able to provide an update on which units are currently stored at SH and Bournemouth please? This list is a little out of date, I fear, and I’d like to correct it…..

Thank you. Do you know if the diagram starting 2Y03 is supposed to come out again in the evening peak, or is it a morning peak only diagram.

Booked to come out for 2R45, the 1615 Hounslow Rounder, which was 8-450 yesterday.

I think the stored 458/4 locations are

Bournemouth 401,403,405-407,410,411,417-420,422,425
Strawberry Hill 408,409,413,416,424,427,428

plus I think that 426 is stored at Wimbledon because it has not been in service for over a month

Yes but SWR promised a lot of things, didn't they, from Portsmouth to Weymouth trains to exclusively Wessex Electrics on the Portsmouth fasts
I thought it was one of the many promises that ended up dead and buried.

To be fair it was probably the public objections that led to Portsmouth - Weymouth being binned. Minor stations to Weymouth would have lost their direct service to Waterloo, IIRC. That aspect was withdrawn during consultation.

And the whole Dec 2019 timetable proposal first got postponed due to the late arrival of the 701s, then shelved due to Covid.
