A new set of murals are making a colorfusl splash along a stretch of Amtrak lines in Philadelphia.
As part of the city's Mural Arts Program, German artist Katharina Grosse painted warehouses and abandoned lots visible from the tracks. Around 34,000 rail passengers will see the project every day from their seats on Amtrak's Northeast Corridor route between Philadelphia and New York, as well as from several local commuter lines.
Installation of the seven murals, collectively entitled psycholustro, took several weeks to complete, and while the arts program will actively maintain the sites for six months, the murals will be left to the elements after that.
Have you seen the murals yet? Riders are encouraged to share their photos on social media with the hashtag #psycholustro.
