I am trying to figure out the train schedule going from Cologne to Volklingen. When I look at the details, it appears that the times listed are only for trains running from Monday through Friday. I have looked at both the German and the English versions. I want to travel on Sunday. When I select the day, I do have various departure times, but the details show only "Runs Mo-Fri" for example.
Do I believe this information? It is a bit difficult to understand how I can select a Sunday and come up with a scheduled time which then seem to imply that the trains only go to Volklingen on weekdays.
What am I not understanding?
