I will mention that I am not from New York, I am from Canada, so I know very little about the subway. Hopefully my questions can be answered.
So some friends of mine are visiting NYC this December, and are transit fanners. They will be spending most of their time rail fanning, and bus fanning too. They have some questions about the R42s as they want to get some good photos and know when they run and on what line.
They want to know where to find R42s, when is the best time to find them, the best place to find them and when, and some good spots to get photos.
I appreciate your answers!
