context_page_description: Gerrards Cross railway station is a railway station in the town of Gerrards Cross in Buckinghamshire, England. It is on the Chiltern Main Line between Denham Golf Club and Seer Green and Jordans.
context_section_description: A development by the Tesco supermarket chain turned the cutting on the London side of the station into a tunnel by the use of large concrete ring segments to form the tunnel profile. The space on top of these segments was filled in to form a ground surface on which the new supermarket was built.
