Photo by myself at the 81st Street subway station on the Upper West Side.
A subway conductor stuck her head out to check whether all was clear before the train moved. This is routine business on every train - they look in one direction, then the other, then back to the first direction.
Just after I took this photo, the conductor looked right at me and gave me a big smile, which was nice.
