You are almost contradicting yourself.. Plymouth/Penzance will not be getting 9 cars over a 10 splitting just because it takes a while to do it, not how railway operations work. Clearly, considering you work in the railway, you’d have a knowledge of the basics in diagramming.
When SWT overhauled their timetable in 2004 they reduced the amount of splitting and joining to aid reliability. When the IEP was in the early stages of being specified electric trains being hauled over non-wired lines by diesel locos were ruled out due to the time taken for coupling and uncoupling.

So clearly such things have been a factor in railway operations, at least in the recent past.

Exactly. When it suits they want to cut down delays but not when it's inconvenient. 1a79 13 late off Plymouth today after an on time arrival due to the need to couple up.

Not quite the whole story - it wasn’t an on time arrival, it was held outside waiting for the driver of the additional attachment to move the additional unit back to the London end of the platform....

It was diagrammed as 10 through from Penzance, I don’t know what happened to it’s partner as Long Rock had enough (and right 5/9 mix) units last night.

I’d take a late, full-length train over an ontime 5 vice 10; if the option to strengthen was on the table.

I have never once said I don't believe the Cotswold peaks should be anything except 9 cars. What I disagree with is the off peak use of 9 car sets to Hereford and the likes all the while delays are being accrued at Plymouth consistently due to trouble splitting and joining 5 car sets. How long before passengers down here say enough is enough with the frequent delays and abandon the railways? Forgive me for looking out for the customers who pay my wages ......

I understand that now but your posts for a long period have always been 'Cotswold Line, nine-car, this that and the other, all bad, all nine-cars should go to Cornwall, etc' with off-peak not being mentioned, while we have also had various things about the Cotswold Line just being a commuter route and that there is somehow something different between a three-hour journey to Plymouth and a three-hour journey to Hereford and so on.

And the fact of the matter is that once a set disappears off to Cornwall at the end of the morning peak, it ain't going to get back to London in time to work a peak service our of Paddington to anywhere - unlike one working an off-peak train goes to Oxford, Worcester or Hereford.

As I have noted in another thread, some of the equivalent services to off-peak Cotswold Line trains currently worked by nine-car trains will likely switch to five-car sets in December - and no one around here will start bleating about that, as some of us actually recognise that different sizes of train are appropriate at different point in the day/week/year.

The state of the track in Plymouth station when it comes to coupling problems has been questioned here and elsewhere - see the GW Passengers' Forum http://www.firstgreatwestern.info/coffeeshop/index.php?topic=18792.1680 - and problems of coupling related to uneven track at Reading affecting 387s and back in the early 1990s at Paddington affecting coupling of Turbos inter early days noted as well. Both of the latter cases were solved without resorting to using long, fixed-formation trains.

I'm touched by your concern for customers down there who play your wages - the customers elsewhere on GWR also help to pay them, but you have often dismissed those customers as mere commuters who don't count for some reason and should just expect to squeeze into five-car sets come what may.

Now now, we are all adults. I removed some heated exchanges but am sure we can move on.

Can I suggest that we look forward please. Digging out old claims isn't exactly going to be helpful to anyone and can only inflame matters.

It's a big topic many people feel passionate about. Let's keep it on the civil, take a step back if needed sometimes, and lower the need for further intervention. Thank you all.

Does anyone have a list of the GWR Class 800 diagrams for Monday to Saturday please? I have looked on other sites and can only get bits and pieces. Any help would be very much appreciated.

Class 800s do all services from Paddington to Bristol Temple Meads and Cardiff/Swansea. They also do services to Oxford(shared with a few Turbos), Cheltenham Spa, Worcester, Great Malvern and Hereford, but these may occasionally be operated by Turbos.

Not 100% sure, there maybe still a turbo diagram to Worcester/Great Malvern

Two turbos, but only one working to Paddington

2W10 0514 Oxford to Worcester Foregate Street
2E92 0651 Worcester Foregate Street to Didcot Parkway

2E20 0819 Reading to Moreton-in-Marsh
1P23 0950 Moreton-in-Marsh to London Paddington

On Bank Holidays this is a Turbo

1W31 1522 London Paddington to Great Malvern
1P44 1830 Great Malvern to London Paddington

This is an update to my previous post #1827. It is derived from weekday Thames Valley platform end notes and tiger, so it is not official. I apologise for only using headcodes, but as noted previously there are too many trains to type out in detail. The diagrams I show as 800 or 802 will be diagrammed one type or the other but in practice there is a lot of day to day variation (plus 9 vice 10 or 10 vice 9). Likewise the sets that go on to North Pole(NPO) during the day will have a booked next working but in practice maintenance and other operational requirements mean that there is no fixed pattern as to what they do next.

Just to repeat, this list is not official and so it may contain errors (especially West Country trains) but hopefully it may help you as a rough guide.

I have not attempted to do the same for Saturdays as there just seems to be too much week to week variation due to many reasons.

Don't know if it's appropriate for this topic, if not, please move to the correct one. GWR are running a test run up to Banbury tonight. Should be a 5 car 802.

5Z35 0105 London Paddington to Banbury
http://www.realtimetrains.co.uk/train/V05019/2019/07/03/advanced

5Z36 0419 Banbury to London Paddington
http://www.realtimetrains.co.uk/train/V05020/2019/07/03/advanced

Oh yes, that'd be wonderful if IET's ran regularly to Banbury. Hopefully Tackley and Heyford can take a 5-car IET. I presume Kings Sutton as Chiltern Railways make a few calls there still, don't they?

What is the reason for the test run?

It strikes me as odd that everything IEP wise still appears to run under an HST timing load.
Any ideas as to if an 800 / 802 timing loads exist? Or when the schedules may be updated?

Compatibility testing - platform stepping distances, stop marker positioning etc.

IET timing loads exist, but if you use them you have to use IET sectional running times. They’re so vastly different it’s effectively a wholesale timetable rewrite just to introduce IET timing loads.

Schedules will go over to new timing loads and SRTs with the timetable recast in December.

Thanks for that.

Is it possible to say, at this point in time, how much time is shed for a 80x timing load on a Paddington - Cardiff / Swansea compared to the HST?
(I assume a TOC or NR planner could enlighten us).

Correction, the test run will be TOMORROW night. My original post has been edited.

This is what working nights does, losing track of what day it is :D

Or they can be pathed (very smartly, might I say!) as an Electric locomotive, with a load of 802 tonnes, for example!

I’m not sure which part of the problem that solves?

If you change the timing load, you have to change the SRTs. New SRTs means new timetable. There’s no point rewriting the whole timetable in July, only for there to be another clean slate rewrite in December.

The train needs to be able to achieve the SRTs associated with the timing load. An IET can run quite happily on HST timings. The accelerated timings are required for the new timetable in December.

As far as I know, it’s only been used for the IET tests - 1Z77 ran as a “Diesel locomotive with a trailing load of 802 tonnes.”

Depends what you mean by regularly. There should be a limited number of IET services operating to and from Banbury on a regular basis from December, as extensions of some peak services between London and Oxford.

IETs have selective door opening, so the platforms at the intermediate stations along the Cherwell Valley pose no problems whatever and are all longer than Combe and Finstock on the Cotswold Line, where an IET, either five-car or nine-car, calls every weekday afternoon.

It was always intended to clear the Oxford-Banbury route for IET operation. It was shown on a map of routes that would be cleared that was issued by the Department for Transport back in 2011.

Platforms between Oxford and Banbury are only long enough to fit 2 and a half coaches of an IET, meaning only one bicycle storage area will be platformed. I don't know how GWR will safely manage the loading of bicycles, since if anyone's familiar with the peak time services on the line, lots of bikes come from those stations, certainly more than two.

The stepping distances on the stations are also close to being as bad as Shipton on the North Cotswold line.

IETs are not suitable for that line at all.

Two-and-a-half IET coaches is the same as fit at Shipton and Ascott-under-Wychwood and rather more than you get on at either Combe or Finstock, which are so short the cab ends of two-car Turbos are next to the ramps. No one is going to spend a penny piece on altering the platform heights in the Cherwell Valley or at Shipton any time soon.

I doubt the cycle/commuting types are likely to be affected, with any southbound IETs from Banbury fairly early in the morning (and which may not even make any intermediate calls) and well after most of those travelling with bikes will have gone home from Oxford in the other direction on 165s, which may now have nice bike racks but for so many years worked the Cherwell Valley stoppers with no bike spaces at all.

I was only mentioning the length of coaches platformed as some context to the next sentence regarding cycle storage areas. SDO working is fine, nothing wrong with that.

I am familiar with the passenger flow off the services that come in the morning from Banbury, and go back up there in the evening, and I can tell you that it will not be enough.

It's worked well over the years as it has become acceptable to store bikes in the vestibules on Turbos, however since even before IETs became a thing, it has been enforced that bikes need to be stored in specific areas. Are we now supposed to ignore that, due to certainly more than the allowed 2 bikes on platformed areas will be boarding? The vestibule areas will be full of cycles come December TT change on the Cherwell Valley line.

I am aware this is off-topic, so I apologise.

How many more times do I need to say this?

Any use of IETs between Oxford and Banbury from December will be extremely limited. Almost all GWR Cherwell Vally services will still be worked by Turbos.

The IET services are not going to be running at times when the bulk of the people commuting into Oxford from the north for work and back out again around the general 9 to 5 window are travelling, so they are not likely to see an IET unless it is at Oxford station working a service on another route.

I am have often observed a longstanding northbound GWR service leave Oxford at around the time an evening IET service is expected to be running and next to no one ever puts a bike on the Turbo set.

I am afraid you are just making a mountain out of a molehill about any Banbury IET services and bikes.

Now that all the GWR IETs have been delivered why are some services for which they were ordered still operated by Turbos? For example 1D30 14:50 Paddington-Oxford express is diagrammed for a 3-car "suburban" 165/1 or 166, which is often barely adequate for the crowds. We were led to believe that all such services would be IETs by now. Is there a shortage of IETs, perhaps availability issues or delays in commissioning? Just curious!

The 1450 is an in-service positioning move to cycle Turbos between Reading and Oxford; otherwise they’d get stuck in the Oxford area. The opposite-direction move is the 0931 Oxford to Padd; which goes empty back to Reading depot.
