Scotland’s Caledonian Sleeper could be extended beyond London to reach mainland Europe, with a new working group now exploring the proposal, according to reporting from Euronews and the Glasgow Times. The effort focuses on whether the overnight rail service can run further than its current routes, potentially extending service through the Channel Tunnel and onward into mainland Europe. The Glasgow Times says a feasibility study is under way into extending the Glasgow-linked Caledonian Sleeper beyond London and through the Channel Tunnel, aiming to assess practical options and requirements. Euronews similarly reports that the working group begins exploring the possibility of extending the service beyond London, suggesting the project is being considered for implementation later this decade. Both sources frame the work as early-stage planning and investigation rather than a confirmed timetable, emphasizing that the next steps involve examining feasibility, route possibilities, and how such an extension could operate. No specific destination cities, service frequency, or infrastructure changes are detailed in the provided reports.
