I travelled from Zurich to Paris in September 1997. The train came to a standstill somewhere in mid-France in the early hours of the morning and was more than three hours late arriving in Paris. There was no refreshment car as it was an overnight train due in around 5am, so the passengers were hungry and thirsty by the time we arrived.
No explanation was given and although compensation forms were handed out when we left the train there was no suggestion of an apology.
I duly posted my form and am still waiting for my compensation.
