If you don't just chase after the special train, you can discover other beautiful things in the gravel of the tracks.

Hello Jeanny,
a beautiful high-contrast shot of the Shore Bindweed, also called Shore Fence Bindweed.
The plant has several other rather amusing names in different regions due to its growth habit, such as Schlangenwenda (Swabian Alb), Bettseicherli (Geislingen, Göppingen), Regeblume (Switzerland, here with the belief that tearing off the flowers brings rain), or several terms in East Frisia: Düfels-Neigarn [Devil’s Sewing Thread], Theeköpke [Teacup] or Pisspott; in Graubünden, Heizenberg it is called parvenglas; since the flower only opens during the day, Dagblome in Emden, etc.
Best regards, Karl

Hello Karl,
those are funny names for this beautiful and tough blossom. In the gravel bed of the tracks, there was otherwise nothing living to be found here. That's why I believe it survived the weed-killing train.
Thank you for the positive rating and the interesting explanations.
Best regards
Jeanny
