I don't check schedules for the subway in NYC, I just show up. Actually I don't think there is such a thing as a schedule.

Um, in every car; at every station. Use Google images to confirm.

That's not a fixed schedule, it's a current-time-to-arrival.

Edit: I stand corrected. There is a published schedule, I've literally never heard of anyone using it though and I wouldn't rely on it.
