Besides 701023 moved to Farnham on 5Q93, preparing for service soon?
Not much happens to those at Farnham. If it moves back promptly that's usually a good sign otherwise it may be further down the queue.
That fits with my belief that the earlier ones built have suffered more in storage as they have been stored for longer.
Some of the not in passenger service units are used for training. Based on reports on this thread, 002, 015, 024 and 028 seem most likely to be in this category. Excluding those makes the not in passenger service split between 001-030 and 031-060 roughly even.

If we ignore the training units and those still stored then the difference is less dramatic, but still a difference.

701001 - 701030
In service 16 so just over 50%
Training 701002, 701015, 701024 & 701028 (total 4)
Stored 701003 (Derby), 701014 (Eastleigh), 701016 (Eastleigh) & 701027 (Eastlaigh) (total 4)
Being prepared 701003 (Derby), 701004, 701008, 701019, 701023, 701024 & 701029 (total 6)

701031 - 707060
In service 26 so not far off 100%
Training none
Stored none
Being prepared 701032, 701040, 701045 & 701055 (total 4)

Half as many again still being prepared for service in the first half of the 701/0 fleet compared to the second half which is reasonably even.
With a further eight 701/0s in the first half also not in service compared to none in the second half is the significant difference.

Note I count 701028 as training as it only had a very brief stint in service but can at least be argued t be "alive".

Now if I knew which ones were being used for any tests some of the differences might be nearer to even.

The first service ran 15 months ago, and of course some were trained before that date.

Anyone know how much longer a good number of units are needed for training (and I mean training existing staff), there will always be smaller amount of ongoing training of new staff.

I am guessing some training will switch to 5car units, but sounds more like coupling and uncoupling is required training still to learn, the 10car units are virtually pairs of 5cars permanently coupled without the intermediate cabs so rest of train unlikely to need any further training / familiarisation.

5s have an additional compressor on each which the half units on a 10 don't. Aswell as stuff to do with the CCTV which differs on a 5 vs a 10.

Now. I am wondering what the next class 701 deliveries will be.

My feeling is that it is likely that at best one 701/0 per week from Eastleigh (701014, 701016 & 701027).
BUT will they be replaced at Eastleigh by 701/5s from Bicester (15 there). ?

Or maybe pairs of 701/5s straight from Bicester to Wimbledon.
Depends when SWR feel the need for 5car 701/5s OR if the last of the 701/0s get harder and harder.

Cannot forget the few at Derby of course.

But worth keeping an eye out for movements from Bicester.

A recent newsletter said the 10 cars will be pushed into service before the 5 cars begin. I'd have a guess there might be a little overlap once things get to the 55/60 10 car in service mark. Don't forget all crew need further training on the 5s before they are rolled out.

Makes sense.

Diverting resources to the 701/5s while trying to get the remaining 15-odd 701/0s into service would just stretch resources and slow everything down, I'd have thought.

I suppose it depends if there are difficulties with getting the last few 701s into service (which I think is possible) and whether there is a need for five car 701s sooner rather than later (which I am doubtful of).

Just an educated guess, but the /5 roll out will likely revolve to some degree around available stabling space, or lack of, for remaining /0 units, and therefore (I would guess?) the likes of WD, WA, SN, VZ and Feltham driver depots may well take priority in /5 knowledge, although every depot involved in same would need to be covered eventually.

My edit: not forgetting of course any depot that becomes involved in /5 detach/attach, which will likely be mostly at Waterloo, so as you say, better to have all relevant depots up to speed before whole sale roll out.

I’ve noticed the Cobham service gets considerably fewer 701 services / is more 450 heavy than any other SWR Metro route. Is there a reason for this?

That may be your perception but I've just checked RTT. In a 6.5 hour cycle before they started to repeat, both the Chessington and Cobham services had five 701s and eight 450 pairs.

The latest ORR quarterly report (Oct-Dec 2025) has SWR at 43.16m passenger km. Pre-pandemic (Oct-Dec 2019) was 52.69m km, so now at 81.9% of pre pandemic.

There has definitely been a shift from 5 days per week commuting by some, but clearly if now over 80% of pre-pandemic then reasonable chance many doing at least 4 days. Actually Oct-Dec 2025 had cuts on SWR west of England line, so possibly commuting is back more than raw figures suggest. Of course if most of these commuters are doing Monday-Thursday, then likely to need the whole 701 fleet as ordered in 2017 to cope with these 4 busy days.


I am intrigued why on basis of these numbers you suggest might not need the 5car 701s soon.

Don't quote me entirely on this, but just an educated guess would be due to crewing and traction knowledge at Guildford depot. Most of the Cobham services interwork with the Chessington/Woking circuit, and many of these berth overnight (and begin service) at Guildford, and as such are crewed by Guildford depot who are behind the other depots in terms of 701 competency.

That is the exact reason yes, Chessington/Woking/Guildford via Cobham services generally speaking interwork and form the vast majority of their diagrammed work, and Guildford still has more guards/drivers that don’t sign 701 then those that are trained. You can also throw in Woking depot which, along with Guildford, is not as advanced as the other metro depots with regards to 701 competency. The latter two are 100% trained on 701 now I believe (Waterloo, Wimbledon, Strawberry Hill and Staines).

I’ll also add this for info - Farnham is even further behind than Woking and Guildford, but it’s less of a priority since they only have a couple of peak services in the morning/evening peak, and generally speaking don’t do much metro work (although they do work Reading, Woking via Weybridge and Guildford via Cobham services IIRC).

It may also be that the other routes were prioritised because the trains are busier. I would guess that the Chessington line in particular is relatively quiet. Kingston Loop services in particular spend mopre of their time in the inner suburbs than other services because both ends of the route are at Waterloo.

A (declassified) first class compartment on a 450 was a nice bonus recently when we went to Surbiton recently because our Kingston train was cancelled because of a Six Nations match

Thanks for clarifying. With regards to Woking depot, whilst we're still not 100% with 701 competency yet, we're still significantly ahead of Guildford (and of course Farnham) I would think - almost all of our weekday guards diagrams now include a 701 in some form, and being a former Guildford guard, I'm surprised by how many ex-colleagues I've spoken to who still don't sign 701s.

More than “a couple of peak services”. From memory, around/approaching a quarter of Farnham’s 31 weekday driver duties now have 701 trips booked on them, which will increase further as more of their still booked 450s on the Cobham and Reading line switch to 701. Admittedly that’s probably a much lower percentage than the more suburban orientated duties at Guildford and Woking, but it’s not an entirely insignificant percentage of their duties.

A key question - how many services do SWR have the staff to operate and how many are they recruiting to fill the gap? (a slightly different question to #units as lots of current 8car 450 would get replaced by 10car 701 and the 450s would go to lengthen long distance 450 services and potential reinstate some too).

The general feeling year ago (and before) in the First group controlled era was that SWR had a significant staffing gap to be able to use all the 701s, has this changed under more direct DfT control?

Good question. And it will take an age for any new drivers to come through.

On the subject of drivers trained on 701s. SWR could be a long way short. After all we now have 43 x 701/0s available for service. That is 43 out of 75 10car equivalents (60 x10 car + 15 x 5car pairs) - that is just short of 60% of the 701 fleet available. I am not saying 40% of drivers who will end up driving 701s are not trained yet but assuming half that means diagramming still has to be done a little carefully.

It will be interesting to see how many 701/os are yet to enter service (if any) when 701/5s start entering service. And when 701/5s might start to enter service - another learning curve.

Based on the previously reported pace of training if SWR are still a long way short then surely something has gone very wrong.

Anything other than 701s on Reading services is getting increasingly rarer. Given the number of depots involved in running that line I doubt if SWR could be both a long way short of trained drivers and at the same time routinely crew the predominant 701 diagrams.

I could have worded that first sentence a bit better - a long way short at some depots. My next sentences highlight how diagramming units vs staff might still feel a long way short of ideal. I feel 20% (a very rough figure) not yet trained might be a long way short. It really depends how many are actually trained and I do not know that.

The point is only just over half the 701 fleet are in service - so far. So plenty of room for untrained drivers to exist and be fully occupied on other classes - but still present a diagramming challenge.

I wonder how close the 701 roll out is to the stage where the number of drivers not yet trained becomes nil - thus a hurdle removed. Now 701s are coming on stream quite regularly there must be less concern at having trained drivers whose experience expires (after six months iirc ?). A tipping point reached ?.

Regarding the "cab modifications", have ANY actually had cab modifications ? I think this was discussed much earlier in this thread and was denounced as a complete red herring, ie: not true ! (But, I am open to be corrected).
As far as I can tell from before and after photos the driver's desk has been changed from the standard Aventra dark grey to non-standard white and maybe one or two buttons relocated.

From my observations, trains towards Epsom, and trains which stop at New Malden are rammed in the peaks. The Woking and Guildford via Cobham trains are less busy.

If you zoom in and click on stations like New Malden on the Tim Jupp map that came out after the station usage figures late 2025, it is fairly obvious the passenger numbers growth path is much steeper than some stations on Cobham line.
The figures are now a year out of date so may well have climbed above the pre pandemic usage levels assuming recent trend has continued.


It does appear 701s have been introduced quickest for operational conveinience, (leave training at depots like Guildford and Woking to near end), rather than targeting routes with passenger numbers regrowing fastest.

Trying to work this out: Have we now reached a point where sufficient amounts of trained drivers are the limiting factor with regards to further diagram introduction, rather than available units?

It's not as acute a problem as before though, as all units planned to be off leased are now off leased (not sure of the timescale for releasing the 458/4s)

Given the complexity of crew and unit diagramming then operational convenience would have to come to the fore.

Perhaps if the roll out had gone smoother earlier then the side effects would not be so bad.

This is what I am wondering. Made worse perhaps if many drivers are already doing overtime as more or less standard. So no options to throw last minute overtime at a rostering problem that appears at the last minute.
