Due to work in connection with ETCS (digital signalling) between Peterborough and Kings Cross there will be no Grand Central trains running over the weekends of 6th/7th or 13th/14th January. The last southbound trains on the Friday evenings and the first northbound trains on the Monday mornings will also be cancelled. There are no trains at all scheduled to run south of Grantham, so no services by any operator into Kings Cross
