The N and R are Broadway locals; the Q is the Broadway express. But during times when there are construction/maintenance projects, route alterations are possible. And when the Q operates to/from Queens, it uses the local tracks at 57th Street station, as the express tracks do not connect to the Astoria line.
Actually the Q always runs to Queens now with the termination of the W and the N should always be a Broadway Local but on the weekend its usually a free for all so one just needs to pay close attention to the announcements.
