Engineering work is taking place between Kentish Town and Radlett after 23:00, closing some lines.
As a result, some trains that usually run from Rainham to West Hampstead Thameslink will instead run between Rainham and Kentish Town. Customers for West Hampstead Thameslink should change at London St Pancras International for alternative Thameslink services.
