Due to the Kings Cross engineering blockade there are no services to London this weekend by any operator. Also because of engineering work on the Durham coast, Northern trains are replaced by buses between Sunderland and Middlesbrough so Seaham, Hartlepool, Seaton Carew and Billingham will have a train free weekend!
Northern introduce their new Autumn timetable from 14th September whilst Grand Central add the fifth sevices (four on a Sunday) with evening services south and early morning services north with effect from 20th September.
