The Chinnor and Princes Risborough Railway is a preserved standard gauge heritage railway with its headquarters and main station at Chinnor in South Oxfordshire, England. It runs along the foot of the Chilterns escarpment. Although a few fields away it has since been given the nickname 'The Icknield Line' for its connection to the Lower Icknield Way. History The line was part of the former Great Western Railway branch line between Watlington and Princes Risborough. British Railways closed the line to passenger traffic in 1957. The section between Chinnor and Princes Risborough thereafter carried a freight-only cement service until 1989. Preservation Reopening The Chinnor and Princes Risborough Railway Association was formed around August 1989. On 19 May 1991, the first train - a works train headed by a 0-4-0 Baguley diesel - ran from Chinnor. It began to operate passenger trains between Chinnor and the site of the former Wainhill Halt (about 1 km NE of Chinnor) in August 1994. In 1995, the route was extended by about 3 km to Horsenden Lane, and then to the old rail connection that led trains to Oxford now known as Thame Junction in 1996. On 21 February 2016, the railway was connected to the main line at Princes Risborough, with services commencing later that year running in to a siding adjacent to Platform 4 at Princes Risborough while works were being undertaken to rebuild the platform there. Some service trains were not always able to run that far either due to Network Rail / Chiltern Railways requirements or other works related to platform reinstatement and continued to terminate at Thame Junction. The railway now operates between Chinnor and platform 4 at Princes Risborough, although some services may continue to terminate and turn around at Thame Junction for operational reasons. There is no platform at Thame Junction. Work to reinstate platform 4 at Princes Risborough was completed in August 2018. Princes Risborough extension Following discussions with Network Rail, an extension of about a mile (1.5 km) to Princes Risborough main line railway station was undertaken, with a view to running into Princes Risborough station. This would allow passengers to connect from Chiltern Railways services on the Chiltern Main Line. Previously, the line was reconnected at a point just yards from the headshunt at Thame Junction for special events to allow trains to run into Princes Risborough station: in October 2013, the line was
