Five out of seven

Long day, train from Cambridge, Eurostar to Brussels and then ICE to our destination. Only just caught the ICE because the platform was changed and it was only by luck I saw the ICE train three platforms away and could see the departure time was the same as on our tickets.
There were problems on the line so despite doing nearly 300 km/h sometimes, at others it was stopped waiting for some other train to clear the next station. Once we had one delay we lost our slot and it was 25 mins late arriving.
An even longer journey tomorrow with an early start.
Have you guessed where we are yet? It is written in neon lights at the end of the station!
