Currently, the signs in the subway are perpendicular to the car. As a result, it’s actually tougher to see where you are if you’re on the train.
If the signs were parallel to the subway line, it would be easier for travelers to figure out where they are. And this how the signs were originally intended to be installed, as per Bob Noorda & Massimo Vignelli…but designer suggestions can only go so far.
Big thanks to Hamish Smyth of Pentagram for the idea.
