Yes, I was on holiday at St Austell in 1962. Home then was Weston super Mare but I have lived in Cardiff for the past 40 years.
I saw that you are featuring the Portishead branch this month and so attach the following.
These were all taken in the summer of 1960 when my father was in Ham Green Hospital. 82032 was on Pill ("Pill, Pill I love thee still" if you remember Adge Cutler's song!) viaduct.
I came across your site as I have been trying to confirm my memory of an abandoned station at Uphill. The story is that the landowner insisted on a station but never stipulated that trains should stop! I think I remember grassy mounds that could have been platforms but can find no real photographic evidence. From recent pictures there is now no trace.
I will send more pictures from time to time....John Thorn Many thanks John - these will be added to the Portishead collection.
