 The 2nd Duke ensured the new route ran via Quainton, near his estates around Wotton, instead of a more direct route via Pitchcott.Beset by financial difficulties, the line took over eight years to build, eventually opening on 23 September 1868.The new line was connected to the Wycombe Railway's Aylesbury station, and joined the Buckinghamshire Railway where the Oxford–Bletchley line and the line to Buckingham met.
