Westfalenbahn (and former Abellio) make great efforts keeping their vehicles clean. But the graphiti-epidemic is not really controllable. So Westfalenbahn try to make the vandalism unattractive with stickers, wich distort the impression of the "art-work". Seen on Westfalenbahn ET 413 in Rheine on 8th of July 2022.
