Glasgow Central Station, the busiest railway station in Scotland, has extensive opening hours to accommodate commuters and long-distance travelers. From Monday to Saturday, the station building generally opens at 04:00 AM and remains open until 00:30 AM (past midnight). On Sundays, the station opens slightly later at 07:00 AM and also closes at 00:30 AM. It is important to note that these are the hours for the main concourse and building access; individual facilities like the ticket office, shops, and the left luggage office have their own specific schedules. For instance, the main ticket office typically operates from 06:00 to 23:25 on weekdays. If you have an exceptionally early or late train, you should check your specific departure time, as the final trains usually depart shortly before the station doors are locked for nightly maintenance. For passengers arriving on the "Caledonian Sleeper" service, the station provides access to lounge facilities during their operating hours, which often align with the sleeper's arrival and departure times.
