Katharina Grosse has spray-painted some decrepit warehouses, collapsed chain-link fences, and scorched weeds that border the tracks with several coats of high intensity acrylic paint.

Seven ‘murals’ collected under the name Psychylustro, dot the path between the 30th Street Station in Philadelphia and Atlantic City in New Jersey, USA.

The 34,000 travelers who ride the rails on a daily basis are reminded about their city’s aesthetics.
