For Duxford, although Whittlesford is the nearest railway station, if you don't fancy the 2km walk, Audley End station is a better option.. .Almost every train stops at Audley End, and there are always taxis outside, whereas you'll be very lucky to find a taxi at Whittlesford unless you've pre-booked. A taxi from Audley End to Duxford will probably cost around GBP15.
