With thanks to
@winsaw for posting the diagrams I probably had my final rides on a HST, at least on the mainline.
Initially planned for yesterday but when at 09:00 I checked on
https://www.realtimetrains.co.uk/ I found the 2U14 was cancelled.
Today at 09:15 running on time and the 2C69 had left Cardiff on time.
As staying in Torbay with a Devon Day Ranger my plan was 2U14 Newton Abott to Tiverton Parkway timetabled arrival 10:58 then 2C69 timetabled arrival 11:08 to Plymouth. The 2U14 was 3 minutes down at Newton Abott but with 6 minutes allowed at Exeter departed on schedule. The 2C69 was on schedule.
Looking now at
https://www.realtimetrains.co.uk/ to get the numbers I see the 2U14 did get to 5 minutes down between Hemerdon and Ivybridge then was terminated at Bristol with a train fault (M8). Other than into Bristol it kept to time. Following on the 2C79 started at Exeter, the reason given an issue with the train crew (TG). 2U14 shows as 43040 and 43098 while 2C79 as 43172 and 43192 so the set swapped.
2C69 was 43194 and 43027.
Aside from the big banks e.g. Hemerdon can the Castle sets keep to time on one power car?
The sets are tired although both carriages and seats I was in were tidy. Similarly even with the power car upgrades they are neither fuel efficient or environmentally friendly. To me a more pleasent experience than the IET I returned from Plymouth on. The current seats are comfortable just large combined with most seating being airline. I understand the safety issues with the original seats but if as the Chiltern hauled stock I prefer the more open environment.
I could not get the wi-fi to log-in. I got the GWR home page and a couple of pages from it but nothing else. I did manange to connect later in an IET.
