I scanned the Eurostar site and sure enough there was ‘technical problem’. Passengers with onward connections advised to have their tickets validated for the next available train. Our intrepid traveller did all this and was delighted that Gare de Lyon chap printed him out a real TGV ticket which he will treasure🤗
Anyway the replacement journey arrived to the very second at Avignon and we were home in time for The Connecting Wall and Missing Vowels (guess what iphone subbed for this!), followed by UC and late night lasagna.
