Title: Swindon to Oxford - 26/11 27/11
Post by: tomL on November 27, 2014, 16:25:07
Yesterday evening I was at an event in Oxford, I took the 17:59 from Swindon to Didcot, changing for Oxford. Some thoughts:

- After just missing the 17:35 there seems to be quite a gap (especially when the 17:29, albeit late, and 17:41 come and go, both avoiding Didcot)
- The changes at Didcot going TO Oxford aren't that bad. The short hop between platform 2 and 3 help greatly here.
- Coming back on the late evening services from Oxford are mediocre at best. It was by luck that the 23:12 (I think?) to Bristol Temple Meads was late enough for me to make the connection. I suspect this won't last forever when all the works are finished.

Side note: while waiting at Swindon I happened to witness a passenger appear at one of the doors of the 17:29 after locking and trying to get off:

Dispatch:"too late doors are looked, sir"
Passenger: "I'll climb out the window then"

He eventually saw sense to not bother, but really?!  ???

I'll be making the same journey tonight although I fear it may be hampered by the relief line block at Ealing. Will update later.

On the way home tonight I was just able to see the 23:13 depart Didcot as many of us arrived from Oxford. Some better connections would be lovely.  ;D

From which direction though?

How many different options are there at Didcot? Six, I think. You just can't timetable well enough to provide connections for all directions....

There are four connecting route flows which create a pretty healthy flow of passengers:

1) Oxford to Swindon/Bath/Bristol
2) Oxford to Swindon/Cardiff
3) Cardiff/Swindon to Oxford
4) Bristol/Bath/Swindon to Oxford

Looking at the current off-peak timetable and you have the following typical gaps (bearing in mind the 30-minute frequency means that will be the longest ever wait).

Flow 1:  22-24 minutes
Flow 2:  7-9 minutes
Flow 3:  9 minutes
Flow 4:  Generally alternates between 27 minutes one hour and 10 minutes the other

So, generally the connections to/from the Cardiff trains work very well, perfectly in fact, but the connections to/from the Bristol trains (which is the larger of the two route flows) is usually pretty poor.  Shame it's not the other way round, but that would mean the timetable being completely recast, and there's nowhere near enough people travelling on that route to justify that.  It's especially annoying to see the arrival from Bristol at xx:28 coming in a minute or two early (as it often does), just as the xx:25 to Oxford pulls out though!

Two ways of it becoming better; 1) You see how the toss of the coin comes out after the new IEP timetables start in 2017, or 2) You provide a nice handy hourly through service between Bristol and Oxford (and beyond to Bedford at the end of the decade when the East-West Rail service commences) using 110mph 4-car Class 387 EMUs which could also provide the catalyst for opening several new stations including Wantage Road, Wootton Bassett and Corsham.

I know which of those options I favour!  ;)

Not much in the Western Route Study about option 2, so option 1 is most likely.

*Except* the suggested IEP TT only allows for fast extra trains that won't be stopping at Didcot (fast to BPW), so whatever the recast timetable, connections won't get much better and could easily get worse.

Until both Oxford - Didcot *and* Didcot-Swindon get 4-tracked, there's little option until East-WEst comes in, and that might well take the West curve owing to lack of capacity around Didcot.

Yes, I agree.  Though there are at least a couple of mentions in the Western Route Study which is better than nothing, and schemes can very quickly climb or fall down the list depending on a range of things such as cost and political will.  For example, the current 'Electric Spine' programme pretty much came out of nowhere.

I'd be pretty happy with a Swindon<>Oxford service that avoided Didcot and went round the west curve if capacity was an issue.  Would help journey times.

I was making this connection a few months ago.  Just as we were entering Didcot Parkway, our on the ball Train Manager announced that the 2025 train to Oxford was running late and if we made our way quickly to Platform 3 we would see it pulling in.  We duly arrived at Oxford almost 30 minutes early.

Interesting thing is that if the were to extend the Cheltenham Spa service that sits in the bay at Swindon for 74 minutes in every 2 hours to Oxford (running time about 30 minutes from Swindon) you even have the stock to make an occasional trip.  If the timing's not robust enough, note that these services also have a 33 minute turn around at Cheltenham Spa, and the northbound could be moved a few minutes later / southbound a few minutes earlier now that the two units on the service can pass each other south of Kemble on what was previously a single line.

This would definitely be interesting. Although would the 15x be fast enough to go between Swindon and Didcot without holding too much up?

At least one of the two units on Cheltenham Spa to Swindon is routinely a class 158, which is 90 m.p.h. capable.  Leaving Swindon just after a London train, Foxcote junction should be reached before the next London train - 15 minutes later - catches up.   

The danger of my suggestion, though, is that it's only an interim as the local units on the Stroud Valley become IEPs to London in 2017.  And there's the fact that it's only going to be two-hourly.   A far better solution is running something that comes up via Chippenham on an hourly basis up to Oxford ... from 2017 that would be electric.

Another consideration on the Didcot-Oxford train timings is the connection to/from cross country services at Oxford. These were supposed to be 'improved' after the Didcot stops were eliminated from CC but I never noticed much. Ultimately an increase of the frequency to 3 an hour ought to be able to improve things all round.

Hope I'm not quoting too much out of context here ... Wantage Road again ( a.k.a. Grove) From the Oxford Mail (https://www.oxfordmail.co.uk/news/17479385.grove-oxford-heathrow-rail-link-proposed-in-new-station-talks/)

Quote
A NEW train link could take passengers from the village of Grove, through Oxford to Heathrow Airport.

That is the latest vision of Wantage MP Ed Vaizey, who recently met with a minister to discuss the proposal.

The idea is part of Mr Vaizey's campaign to get the old Grove railway station reopened.

The saga has run for years, but in July he said the station's reopening was becoming a ‘considerably more positive prospect’.

Last week he met Parliamentary Undersecretary of State Andrew Jones to discuss the issue and raised the idea of a Western Rail link to Heathrow.

Land has already been set aside for building a new station on the railway at Grove on both sides of the A338, north of the Williams F1 headquarters.

Mr Vaizey said there was a 'wide-ranging discussion' about the county's provision of rail services.

'Developing a strategic case' for the reopening of Grove Station was mooted as part of a broader project to improve commuter services between Oxford and Bristol, while 'strategic improvements' to Oxford Station and the Oxford-Didcot line were also covered.

Various rail and department for transport officials also attended.

Mr Vaizey said: “I am delighted that the Minister took the time to meet me and local colleagues to discuss these important projects.

"We will continue to work with the Department and local rail partners to develop strategic schemes to improve services.

"On guidance from the Department and Network Rail I will be looking at the East West Rail scheme and the Cotswold Line Promotion Group for inspiration in how to build a business case for improvements to commuter services between Oxford & Bristol and hope that colleagues in Parliament with stations along that route might join me.”

Wantage's nearest rail station is currently Didcot Parkway.

yeah, right. Delete Oxford & he might be getting close(r)!!

Journalists - all he had to do was look at the map....

The does seem to be an increasing amount of 'noise' regarding Bristol to Oxford and, by association, Swindon to Oxford in the recent past.  Hopefully that will come to something - perhaps as part of East-West Rail as I and others have suggested many times.

East West Rail is the obvious service to extend west of Oxford - assuming 2tph on EWR, that'll be one to Reading / Heathrow? and one to maybe Bristol?

But Grove station was the immediate posts above mine, and until it's 4-tracked, I can't see that there's any capacity. Especially as the suburban electrics will be starting back from Swindon in the not to distant future.

Grove is in the middle of a 4-track section that goes from the proposed station site (former Wantage Road Station) to the site of the former Challow Station.

oh, ok, i thought it was 2-track with a long 'siding' used by the old Didcot power station. thanks.

I'm somewhat surprised then that a Grip1 study / business case hasn't been done by now.

It is in a 4-track section, but two of the four tracks are basically used as extended freight loops, where slower trains (two or three at a time on occasions) can recess and await the passage of faster trains.  I'm not sure opening a station on those loops would be a good idea, unless you provided additional crossovers within them, so there would still be capacity for parking up a freight and stopping a passenger train.  Either that, or more provision for recessing slower trains, especially towards the Swindon direction.  A similar lengthy four track section somewhere west of Uffington and then you might be talking. 

I can't see the whole route as far as Swindon being four-tracked as some have suggested as there would be quite significant civil engineering needed.

From a few minutes ago:

(http://www.firstgreatwestern.info/openwantage.png)

Noting passenger train overtaking (or is it undertaking) a freight.

Suggested crossovers from 992 to 988 and from 987 to 993 would not be cheap, but they would be as but single pebbles on a beach compared to full 4 tracking, and would retain two eastbound and two westbound overtaking sections even when the Weymouth to Great Yarmouth train ;D was calling.

Two 4 track sections were put in by GWR in the 1930's. Both were taken out in 1960's, but the Wantage to Challow section was requadrified in the 1990's.  The other section was an extended section around Shrivenham.

From memory, there is some scope to extend the 4 track west of Challow without too much civil engineering, but major earthworks would be required just east of Uffington.  The Shrivenham 4 track started not far west of Uffington and went on nearly until Bourton.

The major barriers to full 4 track would be Steventon just west of Didcot (where there are houses quite close on both sides) and Stratton on the eastern approach to Swindon where there is a deep cutting. Both these section also have major trunk road bridges over the tracks. There are also some significant embankments between Steventon and Wantage/Grove.

I suppose the question is how much do you have to do to make a difference?
