I understand that there is a C7 bus in Cambridge which goes to Duxford. Can this be picked up near the train station? How close does it go to the IWM Duxford and the airfield? Does the bus run on a Sunday (I couldn't find any on the National Express website)? Is there any taxi service between the 2 towns?
I am planning a trip in July and we will be staying in London, catching the train to Cambridge.
