@nprofile1q... @nprofile1q... Neither DB nor CD can sell me a reservation. DB says „Mittlere Auslastung erwartet“, but then claims a reservation is not possible. Same with CD.
I remember this being the case when we booked the trip back in February, the day the tickets became available. No luck with the early train, that's why we chose the later one. Now, of course, it's questionable whether we can make it back to Cologne on that day.
