I am German and would like to take the train from Stuttgart to Glasgow in August. A flight would be shorter, but I want to take care of the environment and enjoy the landscape a little, not everything has to be fast. Unfortunately I will have to book from different websites and different providers. (Deutsche Bahn GmBH, Eurostar, whatever travels between London and Glasgow) From my experience in Germany I know that trains are sometimes simply cancelled and nobody is interested in how someone gets home.
Does anyone have experience with international trains? What happens if they are cancelled? I don't feel like getting stuck in London because the train from Glasgow is cancelled. In Germany it would be a minor problem because I always get from A to B here somehow, but I don't want to experience it abroad.
