The Berlin transit company’s workers discovered early Friday morning that someone had filled an U-Bahn carriage parked in storage with dried leaves, covering the entire floor and all the seats, Tagesspiegel reported on Saturday.
The clean-up effort involving brooms and fans lasted several hours and caused delays due to the train being out of service.
The trick was presumably the work of graffiti artists, Tagesspiegel explains, because an image of the autumnal U-Bahn scene was posted on the Facebook page Berlin Writers, a magazine and website dedicated to street art.
The post had the caption “Autumn is here!” And was shared more than 500 times as of Friday.
But not everyone was amused.
“Think about the passengers who had to work and because of you the train didn't come,” one Facebook user wrote.
