A rail operator has announced that numerous train services throughout East and West Sussex will undergo alterations during the upcoming festive period. Commencing 21 December, a reduced number of services will operate as the rail network prepares for the Christmas and New Year holidays. Although no major engineering works are scheduled within Sussex itself, services will significantly deviate from their regular schedules due to closures on other parts of the Thameslink network. These closures include the route between Harpenden and London from 21 December to 29 December, between Herne Hill and St Pancras from 25 December to 29 December, and between Cambridge North and Royston from 27 December to 5 January. This report examines the rail services in Sussex that Govia Thameslink Railway (GTR) states will be operational over the forthcoming two weeks. Gatwick Express services are scheduled to be suspended on Christmas Day and Boxing Day, and will operate according to an altered timetable from 21 December through 5 January. Travelers requiring more detailed journey information, including impacts on services provided by other train operators, are advised to utilize the National Rail journey planner tool.
