Children playing on the tracks caused delays on the railway line between Hamburg and Sylt on Monday afternoon.
Railway employees had observed the two girls and two boys aged ten to twelve as they ran several times between the platforms in the Berg train station (Dithmarschen district), as the federal police announced on Tuesday.
Burg - The Hamburg - Westerland railway line was temporarily closed at Burg.
Four trains were delayed.
The children were instructed about the mortal danger and then handed over to their parents.
In this context, the federal police again warned against stepping on the tracks.
This is life-threatening and not prohibited for nothing.
Trains approached almost silently and, depending on the wind direction, could often only be noticed very late.
In addition, the braking distance of a train is up to one kilometer.
