The majority of our trains are steam hauled, however diesel engines are used at off peak and other times. Every effort will be made to ensure running as timetable, but the Welsh Highland Railway does not guarantee advertised connections nor the advertised traction in the event of breakdown or other obstruction of services.

All departure times are from Caernarfon Station (except times in red = ex Dinas). Click on the date for the full timetable.
