I had an Anytime single, bought on the rail forum ticket split site, £35.30.
My planned itinerary was
01/08/25
Abergavenny 1805 TfW
Newport arr 1832
dep 1844 GWR
Bristol TM (BRI) arr 1920
BRI dep 1950 XC
Taunton arr 2020
My journey was as above until Bristol TM where I used instead:
BRI 1953 (actual dep. 2000)
TAU (actual arr. 2114)
I could have opted for the delayed XC actual dep 2008 and actually arrived Taunton 2139 but opted for the GWR as it arrived and departed Bristol TM first. I knew it was slower, but ironically was delayed more by waiting at Bedminster for 9 mins to allow the XC I could have caught to pass.
The delayed XC I didn't take was the very late 1845 dep. There was a safety inspection of the track, so every train from the north was delayed.
On the last train, the GWR train manager kept saying to claim delay repay as there was a 15 plus minute delay.
So my journey could have been a 19 minute delay had I took the XC from Bristol, but was actually 54 minutes.
