I may have been taking public transportation for my entire life, but people-watching on the subway never gets old. Even when I’m trying to block out my fellow commuters—with my headphones turned up and/or a magazine in front of my face—I can’t help but wonder what their backstories are: Why are they also headed home so late? Where are they coming from? Who’s waiting up for them? And so on.

Bee Johnson is similarly intrigued by NYC subway riders. The Harlem-based artist has taken to capturing them in her series, “The Illustrated Train.”

The project is exactly what it sounds like. As Micropolis NYCВ quotes Johnson:

If I happen to be standing on a crowded train and can’t comfortably draw or only have a stop before I have to get off, I’ll try to discreetly snap a photo (no flash!) with my phone and base my illo on that. (I know I sound like a total creep, but what can you do? Sometimes the best ones are gone in a flash.)

A few of my favorites illustrations:

…funny enough, I see the guy in the last illo all the time on the A train!
