I took the train back home today. I travelled in the middle of the day and since it is summertime, it was very quiet on the platforms. I had to change trains at Amersfoort and I had 25 minutes to kill. I decided to walk around (with my bike and bags) and suddenly I saw these amazing patterns, shadows, lines and rude materials. The transfer time pass away very quickly and I even had to run to catch my next train!
