Things must have improved. I caught the delayed (roughly) 2030 from Exeter and it was going through to Penzance.
The only time I’ve ever been glad of a late train. We caught the 2006 from Axminster aiming for the 2120 (ish) to Plymouth. We pulled in at platform 3 at Exeter at 2042 as the delayed Penzance train was approaching.
My car was in Plymouth for the weekend as I was out of Liskeard earlier than the first train from Cornwall on Saturday morning, which would have been a contingency with all the cancellations
I think they did, but because trains were removed from the system(s) Realtime Trains uses as it's source, usually a great help at times of disruption and cancellations, wasn't much use yesterday. So yes, I believe some further trains from London did make it to Penzance but we don't have a record of which ones did and which ones didn't in the end. It may have been that
GWR▸ were able to run more trains than expected at the start of the day. Hope for all those who were travelling that they were able to.
