In Berlin they put stickers into fresh panels to destroy the graffiti.
On the stickers is written "Dieser Zug wurde mutwillig beschmutzt/beschadigt.
Wir beseitigen umgehend die Schaden"
That means "this train was dirtied/damaged willfully. We abolish the damage immediate."
That's why i wrote in German
"this End to End will be damaged willfully".
1 day after they did the sticker inside. Perfect !
