Tipp

Tip!

Where is the mistake?
Each stay at a station must be specified by a vertical section of the timetable even if the stay is very short. That means, a stay is described by an arrival point and a departure point at the station.

How you can revise the mistake?

  1. Have a look at the diagram. Can you find a timetable which has only an arrival point or a departure point at a station, respectively? Here you can ignore the first and the last breakpoint of the timetable.
