The subway normally operates 24 hours a day with five different service patterns: rush-hour, midday, evening, weekend and late-night. Each service has a table in its article to show what tracks are used and when. This article lists all the current services, along with their lines and terminals and a brief description; see Unused New York City Subway service labels for unused and defunct services.
In the New York City Subway nomenclature, numbered or lettered "services" use different segments of physical trackage, or "lines". The services that run on certain lines change depending on the time of day.
