Some of the coolest and most detailed art can be found on bridge overpasses and on the sides of trains. However, this is the first time I have seen actual street art on the railroad tacks themselves. Artur Bordalo is the artist behind these awesome creations and you can find his artwork scattered throughout different locations in Portugal.
If you would like to check out more of his artwork, you can do so by going to his website.

This kind of artwork should be mandatory on all railroad tracks. Make sure to share this story on Facebook.
