I reached the station just when the train was leaving. I had to wait for the next train going to Cologne city. I started to eat the hamburgers I was carrying in my bag while listening to music. After 30 minutes I looked at my wrist watch and it was 3 PM, and the next train had not arrived yet. I looked up the train schedule for the next train, and found it would not arrive until 4 PM. I had to continue my wait sitting at the station as there was no market near by to visit. Then, it was 4 PM, and the train still had not yet arrived. I looked at the train schedule again, and realized that today is a Sunday. "There won't be another one till tomorrow morning" said the porter.
