Totally agree on the reservation system. I had it work properly once between Newton Abbot and Taunton a couple of months ago, and it's brilliant.
The cheapest internal fitment on the 800s to me seemed the window blinds. I wonder if they plan to do anything about them...
It would be great for marketing if they could get it down to 100 minutes. (The M4 could sure do with less traffic). I have been assuming that the new faster schedules would be introduced at the start of the summer 2019 timetable - but perhaps I am wrong?
May just be that both drivers aren't signed to drive 802s on electric traction yet.Are class 802s prohibited from running in electric mode? I was on a pair of Class 802 departures from London Paddington earlier and they were on diesel. I also passed an inbound pair of 802s at Slough and they were also on diesel.

No, no blanket prohibition for running in electric however a number of 80x (including several 802s) do have a diesel only restriction for varying reasons. It's likely these you saw.
The RPS archive shows a 1985 special run with a 2+5 formation doing said journey in 80m 45s - speeds up to 130. The same run, on the same day, shows as 80m 39s - in such situations the RPS takes the higher of the times as being correct. With AC to Cardiff a headline time of 100 minutes with stops at Reading, Swindon, B.Parkway and Newport should be alright - just. There must be somebody on the forum who has access to the SRTs for the full AC service?100 minutes to Cardiff would only match what was possible with HST's in 1987!! You would hope it could be nearer 90 mins or even 95...but that seems unlikely to happen.

The short term benefit of HS2 is as a very expensive WCML capacity enhancement programme
When the first IEP’s were delivered, they had a different strip, it was changed to that green before delivery.Or it’s been adopted by GWR due to its presence on IETs
Are 800001/2 now in service?

That would need ETCS fitment to the Western route, which has been descoped on cost grounds as far as I know.Is the intention to run the Inter City Express Trains up to their maximum 140mph
\I don't know the full facts, but my understanding is that due to increased brekaing distance you essentially need a fifth aspect (unless oyou move the signals), which experimentally was the flashing green on the ECML. My impression is that this isn't all that easy to distinguish from a static green in reality. As far as I can find signal spacing for 125mph is 2054m on flat track- but that's the distance from the double yellow to the red; so the actual signals are passing approximately every 18 seconds at 125mph, every 16 seconds at 140mph.Is it really that difficult to read signals at 140mph? I can't see how 15mph over the existing maximum can make such a huge difference. Sure in some places sighting won't allow it, but a blanket ban seems excessive.
The section of the ECML north of York for example, it must be possible to sight signals from several miles away.
Remember too that driver's get an audible signal to warn them of either a caution or clear aspect. It isn't only visual. I guess in respect of signal aspects there were other options other than flashing green. In Italy for example they use various combinations of red and green and green and yellow. So it is conceivable that a fifth aspect could have worked along with a combination of Speed protection such as the French kvb system.\I don't know the full facts, but my understanding is that due to increased brekaing distance you essentially need a fifth aspect (unless oyou move the signals), which experimentally was the flashing green on the ECML.

There are other issues that concern me, but I listed only the most important three.There's plenty more - try post 9125 on page 305 for a flavour.
Perhaps broadgage is getting tired of typing the same things out over and over after so many years. But probably not.
Interesting that list you attached. I also noticed that there were no WCML times ?. Then I realised it was a 100mph railway then so I hope that means it would now exhibit a faster journey - does it ?. And if it does then it suggests to me that for many decades 125mph has been a threshold that we are not getting past .
As I understand it the issue wasn't recognising the flashing green but the risk of a steady green being misinterpreted as a flashing green particularly in wet weather when viewed through an area cleared by a window wiper with the subsequent risk of an overspeed with insufficient braking distance.\I don't know the full facts, but my understanding is that due to increased brekaing distance you essentially need a fifth aspect (unless oyou move the signals), which experimentally was the flashing green on the ECML.

Using contracted units for crew training sounds expensive. But how else were the crew ever supposed to get trained? Surely this isn't unexpected.The planned requirement on the GWR 800 sets has been contracted by the DfT. It’s not an option for GWR to “wind it down”.
GWR have to pay, in the case of the 5 car units, for 32 diagrams a day, seven days a week at a cost of five figures per unit, per day. Even having two of these units at the moment on train crew diagrams is hideously expensive.
If one of those 32 units are not available for a whole day and that non-availability is the fault of Hitachi, GWR only get half that daily payment back, as there is a % “bedding in factor” for the first few years of service. Again that was decided by the DfT.
With the Scottish requirement, there has been no contingency on offer to GWR. The early plans that did have such a contingency (I know they did - I wrote them) were junked when the delays to the Hitachi delivery schedules occurred and no-one was going to move on the HST release dates. Since that point it has been hand to mouth, week to week, trying to get to the next stage of the Cascade plan without having to rewrite it again.
It really is utterly astonishing that Hitachi still get paid even if they don't provide a train. In theory that means they could have the entire fleet sat on depot all day and still get paid 50%. Far better would have been a "no train, no pay" from the outset, with this ratcheting up to a penalty payment from Hitachi for non-delivery in future years once initial reliability has been sorted out. That might have focused a few minds with the supplier.Using contracted units for crew training sounds expensive. But how else were the crew ever supposed to get trained? Surely this isn't unexpected.
If you are only contracting for units produced then we are back at Hitachi charging for something they can't / aren't going to deliver, it is all their fault. At which point you can plan some diagrams around a reduced number of units like with subtracting the two non traffic sets or spend some of the money paid in damages renting something to fill the gaps. The quoted fee of £75,000 per vehicle month works out around £12,500 per day for each 5 car train or perhaps half that if it doesn't make it out of the depot.
Do you really have to pay the other 50% even if the unit is not produced at all? That sounds like money, literally for nothing? Often it has been noted here they are made available but only for the latter part of the day.
The large number of HSTs still around so close now to what was to have been the all IET timetable suggests the whole cascade - new trains in and old trains out - has slipped by a very long way indeed.
No doubt "jimm" will be along shortly to tell us all how the deal is wonderful and in the best interests of those pay (i.e. passengers and taxpayers).
