I’ve ridden the New York City subway system since infancy, sadly I never paid much attention to the intricate tiling, murals and typography throughout many of the stations. However, New York-based designer Adam Chang has opened my eyes to the awesome art work there with his NY Train Project blog, which celebrates the hidden design treasures to be discovered within the city’s underground stations.

Chang who runs the design studio Same Tomorrow—was inspired to begin the blog when he first noticed the 19th century tile and ceramic work in the Bleecker Street station in Greenwich Village. Now he aims to chronicle every subway station in the system. Even if you don’t care about public art, the blog is actually a handy guide to the intricate system.
