I’m under no illusion that the Pompey Direct is special, this problem exists all over the network. My big concern is that by the time you introduce the 701/5s, bring the suburban service back to pre-Covid levels, you won’t have any spare stock to displace, say, a 8x450 off an Alton, Basingstoke or Haslemere service onto a longer distance service.
I can't see suburban services being restored to pre-Covid levels. I very much doubt Reading services will go back to 4tph for four hours across each peak. We'll be lucky to see one additional service in each peak. I also doubt, unfortunately, that Hounslow loop services will be restored in the off-peak.

There is an additional service each way in the peak for the Pompey Direct from December which should help a little. An extra arrival between 0800 and 0900 at Waterloo, and the 1615 to Haslemere will run again.

So, the latest DfT figures include 2 Pompey Direct services and 1 Alton line service in the top 10 most crowded services yet SWR management deny there is a need to strengthen services. These services are booked 10x444, 10x444 and 12x450 so maximum formations.

When have they denied there is a need to strengthen services?

From the December timetable change there is an additional peak time arrival (in the 08.00 hour) into Waterloo from the Portsmouth Direct.

There was a pre timetable consultation opportunity to discuss with managers, and when put to them about the crowding on the Pompey Direct, their comment was that they’d consider it but the Pompey Direct was still so down on passengers that it likely couldn’t be justified - that was in the last 3 months!

In simple terms, if the timetable reverted to how it was at the handover from SWT to SWR (so pre covid in essence), with the suburban entirely covered by 701's, including Readings, there would be adequate stock (450/444) to cover everything else, elecy wise, with all main line trains at maximum (10 or 12 car length) in the peaks. The only limiting factor being certain platforms at Waterloo (5,6 & 7 primarily).

With the apparent removal (so I was informed off record) of unit mileage restrictions(?) for Desiro's, many off peak trains could also remain maximum length theoretically.

The 52,000 seat uplift as mentioned, I am presuming was about the enhanced service proposed, plus reconfiguring of seating in 444/450 in the latest refurb, plus (possibly?) the manner in which the seating vs standing room calculations for 701's were 'spun' for the benefit of public consumption? I might be in cynical mode in that last point..:lol:

OK, I just took a look at the current fleet diagrams.

In my very simplistic uneducated view, the published fleet diagrams show 30 450s being used for suburban work. If we presume these get covered by the 701s, the spare 30 units then are the uplift available across the entire network. Running as pairs, that’s an additional 15 services at any time.

Maybe there is an option for tighter turnarounds. Do units layover longer than they used to?

Anything additional is of course welcomed. The elephant in the room (in relation to the Pompey Direct) has always been that some commentators refuse to accept that the nature of the SW network is such, that most services on all the longer routes, PDL included, have to form a part of the overall integral service pattern, just to keep up with demand, as the infrastructure from Woking Junction inwards will not permit any one route being given cart blanche to run everything for the sole benefit of those who travel from/to the outer reaches of those routes.

Whilst some within the industry have allegedly (I have heard) used (abused?) their position to enhance service levels at certain station(s) over the years, Moley having highlighted one specific example of recent times which was also mentioned to me by someone (no name, no pack drill), the industry in general has to take a wider collective view of the overall situation, whereupon the word 'compromise', is something that the users of all routes must accept at some point or other.

As HamworthyGoods has replied, end of !

To explain turnrounds in timetabling planning in simple terms;

The SW timetable is driven by the capacity, platform occupation and track layout/signalling at Waterloo. Once you have got your head around that and accept same, the rest falls in to place. Plan Waterloo to it's optimum, but legally (by the rules Networkrail have in place) plus a number of small 'firebreaks' (to use the phrase of a-another above I seem to recall?), you will have a fair base for the overall timetable.

Each group of routes (at Waterloo) had its own guidelines/rules, ie, Windsor lines, main lines, main suburban lines.

These rules included such things as minimal turn round times, line of route operation (ie: Weymouth in, formed Weymouth out etc), crew related matters (which I won't go in to here) etc.

After that, connectional opportunities, stopping patterns, frequency, single line sections, junction conflicts (I could go on) need to be planned, and accounted for along the various routes. The last thing that would emerge from all this, would be the turnround times at the country end termini.

Sometimes these would work out OK by chance, but at certain places, Portsmouth Harbour being the most notable in my time, one was met with similar headaches to get around, albeit on a smaller scale in one sense, but also added to by the presence of trains from two other operators, and their associated wishes for their own timetables.

To sum up, turn round times at some outer location may seem excessive to the layman, eg at Alton perhaps, but that is a result of the overall plan as above.

But that does also allow for late running on the DOWN, and also allows for any train (on that route) to be maximum formation (ie: 12 car 450).

I was informed many years ago that the South Western Timetable starting point was the critical flat junction at Woking. Obviously, capacity at Waterloo is critical as well. Is my recollection correct or was correct 40 years ago? Thank you.

Depends to a degree to whom you spoke to, but I and one other in particular (whom has a lot of respect even in retirement) from our time in planning (both 1970's entrants) have always understood Waterloo to be the main focus. Going back to steam days and a timetable that was somewhat less intensive (at Waterloo) within the Main line group of platforms, Woking Junction may well have been perhaps on a more equal footing with Waterloo at that time?

I worked with people who were involved in such planning in steam days, and one listens and learns, as I did.

As regards Woking Junction, a major part of the 2004 timetable revision, was designed around UP and DOWN Portsmouth line trains being timed (where possible in relation to other constraints - eg at Waterloo) to pass one another at Woking Junction, on every half hour (1Pxx) so effectively two trains, one UP and one DOWN, making use of the same timetable slot across what was/is a very busy junction every half hour. As such this might throw up additional pathway slots across the junction at other times 'past the hour' if that makes sense?

The main difference with new timetable is that the performance of the trains can be factored in. Gone are the 442s with their weaker acceleration lower to mid speed.

If it is all 701s on slow lines into Waterloo and all desiros on fast lines then the timetable can be optimised around their performance, even to nearest quarter minute on critical section if trying to squeeze max capacity.

Alas the 159s rather get in the way, and have to optimise allowing for the slowest. In a sensible world would have replaced them with something that can match perfirmance of the electrics. I guess it would be going off topic to query if a 185 could keep up, instead of having to degrade a maximised timetable to accomodate 159s.

It's a bit moot I suppose, but if the infrastructure allowed 444/450 units to run with unrestricted power, could that help deliver meaningful timetable enhancements? It's really striking traveling on a 350 on AC power compared to a 450, the latter feels like snail's pace in comparison. It must hurt when hitting congestion, with these trains taking so long to get back up to running speed.

Without going in to details, the SW has, since the introduction of Desiro's, suffered from power (for traction) restrictions at odd places/times over the years, so AFAIK there has never been any period of timetable when all services have been unrestricted in draw power. I will stand corrected, as such matters were - to my knowledge - never fed down anyone in planning other than (perhaps?) the Head of. Blind leading the blind comes to mind.

I only got to hear about such matters post retirement, as one does...;)

The main difference with new timetable is that the performance of the trains can be factored in.
The 2004 revamp was based on the old 400 stock (VEP/CIG days) schedules, because that was the only TT info in place at the time. Only later could schedules be modified to take account of Desiro capabilities.

4. Lack of 2tph fast to Waterloo at Farnborough (Main) and Fleet

5. Lack of 2tph in the evening Waterloo-Alton, lack of evening peak fast trains from Waterloo-Alton, and generally lack of 1tph fast Waterloo-Alton

6. Slow service into London for major stations Poole, Bournemouth, Southampton Central and Basingstoke
IMHO, all long-haul services should stop at Woking and Basingstoke - naturally, I put in my claim for more stops at Farnborough!

Skipping Woking is not a great idea (IMHO) - it is where the stopper services terminate, so is an obvious interchange. Especially if Southern Rail Access becomes reality...

For Alton and Basingstoke stoppers, I'd have them run non-stop to Woking (possibly stoping at Surbiton) then all-stops to their destination... once Crossrail2 is resurrected, Wimbledon becomes an important interchange

In addition to the rather slow Woking stopper, most stations served by the service also have a faster train into London provided by a longer-distance service. Basingstoke trains serve Weybridge and Walton, with Alton trains picking up the West Byfleet stop. I presume users of both the Alton/Aldershot service and the Basingstoke stopper would prefer if the train ran somewhat faster. But then which service would you stop at West Byfleet, Weybridge, Walton and Surbiton?

Either you double up the Woking stopper (no capacity for that), or perhaps you transfer the calls to the Portsmouth/Haslemere slow trains - but then passengers at Guildford, Godalming, Farncombe and Haslemere complain. The nature of the SWML, with 4 or 5 different speed tiers for services out of Waterloo, but only 4 tracks, means that some compromises have to be made, such as slowing down semifast services.

The Alton to Waterloo service is 2tph
The Basingstoke Stopper to Waterloo is 2tph
The Woking Stopper to Waterloo is 2tph

Why do the sleepy hollows of West Byfleet, Weybridge, or Walton-on-Thames justify 4tph

Is it really 4tph though, or effective 2tph to Waterloo plus a 2tph stopper? I'm not sure what other service would be specified? Just the stopping train?

Is 4tph into Woking bay, and everything else losing stops feasible? Seems like it would cause too many conflicts.

Sleepy hollows? Walton and Weybridge both have passenger figures of around 2.5 million (including people changing at Weybridge), which if anything is enough to justify more than the 4tph they currently have.

They're not sleepy hollows at all - busy commuter towns, with station usage ranging from 1.2M to 2.4M per year. Furthermore, Weybridge is the main interchange for Chertsey and Addlestone, another 500k or so. The Woking stopper can't handle all those passengers, particularly at peak times, and it's anyway 10-15 mins slower than the semifasts. Realistically, Esher, Hersham and Byfleet&NewHaw probably justify 4tph too, the stations aren't as well located but there's surely some suppression of demand by the relatively infrequent service.

Presumably this would only work if the Alton/Basingstoke services were diverted onto the fast lines, but I'm not sure you could fit them in.

Drifting into speculative territory here, but I wonder if it would be worthwhile sending the fast Portsmouth trains via the New Guildford Line, so that the paths via Woking can be used for an additional half-hourly Waterloo - Woking stopper which extends to Guildford. No direct links would be lost as the slow Portsmouth train would provide the link between Woking and all stations south of Haslemere. The Haslemere stopper would scale this up to 2tph from there to Woking.

I don't think that is correct, these aren't sleepy.

However if look at annual station usage, and compare to service frequency of each station, there are some serious mismatches (some with more calls than really deserve, and some skipped disproportionately)

Along SW mainline, station usage is (* served by others too)
Earlsfield 5,569,216
Wimbledon 13,244,236 *
Raynes Park 3,497,682
New Malden 3,077,144
Berrylands 363,954
Surbiton 7,589,564
Esher 877,074
Hersham 722,278
Walton on Thames 2,425,866
Weybridge 1,987,922
Byfleet and New Haw 408,252
West Byfleet 1,172,146
Woking 6,522,202
Brookwood 874,760
Farnborough (main) 2,235,212
Fleet 1,400,680
Winchfield 229,000
Hook 487,728
Basingstoke 4,793,820 *
Micheldever 131,552
Winchester 4,593,936 *
Shawford 140,042
Eastleigh 1,191,848
Southampton Airport Parkway 1,444,254 *
Swaythling 74,572
St Denys 232,936
Southampton Central 6,172,960 *

I am not going to do this for every station, but can soon find oddities, eg Andover 1,141,120 is similar numbers to Eastleigh or West Byfleet, but gets much more sparse service.
IMHO, all long-haul services should stop at Woking and Basingstoke - naturally, I put in my claim for more stops at Farnborough!
Norbiton is busier than Farnborough, so if Farnborough deserves non stop trains, so does Norbiton. Actually Norbiton and Kingston together are over 6600k (more than the total of all stations Brookwood to Hook). But this sort of analysis does question where the fast flights should start to call, operational convenience or where passenger numbers justify it.

Before the current or at least pre COVID timetable came in these stations were served by a 2tph Woking to Waterloo stopper and 2tph Guildford to Waterloo stopper. Worplesdon was generally only served by the Guildford stopper. For some reason SWT withdrew the Guildford stopper and extra calls got added to the Basingstoke and Alton trains as a result. So I suspect the answer is no 4tph to Woking bay is not feasible but routing to of them to Guildford probably would be.

This is fine until a delay at the country end of the Pompey fast means that the fast service gets routed behind the new line stopper, or the new line stopper is delayed and then joins the mainline late and misses its turnaround at Waterloo.

The best answer would be capital investment to build the flyover at Woking.

== Doublepost prevention - post automatically merged: ==

Also the down services to Pompey often picked up delays when there were 4 (off peak) or 6 trains (peak) an hour between Effingham Junction and Guildford.

What was the reason for withdrawal? Were the paths eventually used for something else?

Withdrawn prior to the 2004 change for performance reasons as 6tph crossing at Woking Jn wasn’t reliably deliverable.

When was there 6tph between Effingham Junction and Guildford?

It probably makes sense for the Guildford via Epsom services to skip Horsley and Clandon, which would reduce the chance of knock-on delays to Portsmouth services if they were rerouted this way.

You’d have to send 2tph stoppers to Guildford as there isn’t much capacity for stuff leaving the bay I’d say. Too many conflicts

southern used to run peak time services to Guildford plus the 2tph via Epsom and cobham
