Is this strictly necessary, or is there a risk of getting lost inside?

If these are the stickers Mr Hopwood has been negotiating with Hitachi over then he should have had a go at the Brexit negotiations.

1K04/1K11 Paddington to Newbury and return (just leaving Newbury now on time at 0923) looks to be a (5-car) IET for the first time (that I have seen) today. It's usually an HST.

I use this service on an irregular basis into Paddington from Thatcham and it is usually very lightly loaded west of Reading. 5 cars should be fine for this one.

Not long now till 5-car IET's on all the Bedwyn semi-fasts aswell (hopefully!)

Yes, that diagram was usually a colossal waste of a HST.

Reading drivers are currently going through the training to support introduction of Bedwynís as and when.

Is it a tactile sign?  If so I assume it is so vision-impaired people know where to find the loo and the sink.

19:48 London Paddington to Worcester Shrub Hill due 22:22 will no longer call at Maidenhead.
This is due to a fault on this train.

23:01 Oxford to London Paddington due 00:21 will no longer call at Maidenhead.

Problems with IETs calling at Maidenhead?

Yes, nothing over 5-car can call until an SDO database update which is expected soon.  New diagrams today with more 9-cars on (that stop at Maidenhead) obviously slipped through in error.

19:48 went over to IET for the first time finishing off the last LTP Diagrams for Cheltenham. Some STP until 12 December, after that it would be unlikely to hear the slams on the Golden Valley.

I donít know the issue but I thought drivers can manually release doors. Iíve seen signs up at Westbury that tells drivers how many doors to release.

Iím confused. Are you saying that Maidenhead canít accept >5 cars of any persuasion or just IETs >5 cars?
In either case how soon is Ďsooní for the upgrade?

I ask because the 7.06 MaidenheadPaddington from Worcester is running as a 5 car IET rather than HST for the first time this week (and is Grossly undersized). I had put this down to the Worcester engineering works for the week, but is this a long term change?  If so itís a disaster.

Next month I think the SDO changes, though this might be brought forward if itís creating too many issues?  Not sure why manual door release isnít allowed there but it currently isnít.  Again perhaps thatíll change on a temporary basis if it causes too many issues - thereís no reason in principle why it canít other than signage and driver briefings, although obviously risks increase every time manual door selection is used at a station.  There is also currently a limit of 5-car for DOO operation as well but I donít think any of these trains is DOO.

Iíd suggest everyone makes GWR fully aware how theyíre letting people down.

When is a 5 car train better than a 9 car?  Smiley

For those interested, the Rail Performance Society have provided some freely downloadable IET performance data here: http://www.railperf.org.uk/index/iet  Makes for some interesting reading.

Health Warning: Some files are in EXCEL file format, others in PDF format

An RPS analysis:

If we are talking about net running times - excluding recovery, pathing and performance allowances - the evidence suggests 800's won't..but 802's with that extra bit of power look like they can in some but not all cases.  It depends on a number of factors:
Linespeeds of 125mph - forget it.
Linespeeds of 100mph - HST is generally faster.
Linespeeds of 70 to 90mph - as long as there are no long climbs up adverse gradients.

From what I've observed 1K04/1K11 has been back on an HST this week.

Is this due to the issues with cameras on IET's (mentioned on the "IET's to Bedwyn delayed" thread) and their use for DOO ops?

It shouldnít be - it obviously doesnít run DOO when itís a HST, so no reason why the TM wouldnít be able to dispatch it as an IET.

Understood, was just wondering if the TM would be dispatched with when run by an IET (as is the intention for the Bedwyn's) but obviously not.
