On 14 May 1988, Network SouthEast (Salisbury area) organised the 'Crompton Farewell' railtour, to mark the end of the use of Class 33s on the Cardiff to Portsmouth route. The 1Z10 tour left Waterloo at 08:20, and travelled via Guildford, Southampton and Cardiff, to reach Carmarthen at 16:05. The return working was booked to leave Carmarthen at 16:27. I doubt that it did, as it was 20 minutes late when I photographed it climbing up the grade through Patchway station, being hauled by 33112 Templecombe & 33026.
