Due to engineering works being carried out at Biggleswade, an amended timetable was in operation during Saturdays in the month of January 2005 with GNER services only operating a shuttle between Kings Cross and Stevenage with a Rail Replacement Bus service operating to Peterborough and WAGN Peterborough services being diverted to Letchworth to connect with a rail replacement service.

Hull Trains operated a Cambridge to Hull service so are not represented here.
