Partly. Both UK sleeper services — the Caledonian Sleeper (London–Scotland) and the GWR Night Riviera (London–Penzance) — run six nights a week, Sunday through Friday, but there is no Saturday-night departure. That means you can travel on a Friday night and on a Sunday night, so most of the weekend is covered, but you cannot board a sleeper on Saturday evening. This pattern has been standard for years and reflects weekend engineering work on the rail network. It also runs a reduced or suspended service around Christmas and New Year, so check the festive timetable for those dates. So if you're planning a weekend trip: a Friday-night departure gets you to Scotland or Cornwall to start Saturday, and a Sunday-night departure is popular for heading back or arriving for Monday morning. Just remember Saturday night is the gap. Departure times differ by service and destination — the Highlands 'Highlander' leaves London earliest (around 21:15), the Edinburgh/Glasgow 'Lowlander' just before midnight, and the Night Riviera to Cornwall late evening. Because timetables change and engineering works can alter individual nights, always check the live timetable for your specific date, especially around bank holidays and the festive season.
