LONDON COMMUTERS and users of both Gatwick and Luton airports should note that Thameslink rail services will be disrupted every weekend through to Christmas as infrastructure work for the St Pancras Eurostar terminal takes place. Trains will terminate at Kentish Town and either London Bridge or Blackfriars. From London Bridge travellers can take the Jubilee to West Hampstead (a walk for the change) or the Northern Line to Kentish Town (where it is far easier). From late Christmas Eve until Monday 5 January 2004 there will again be no services.
