Cookham station on the Maidenhead to Marlow branch line. The Great Western railway still has many rather quirky branch lines that require the train to reverse en-route, this is one of them, with the train having to reverse at Bourne End. In this case because the line used to be a through route to High Wycombe and a branch line off that to Marlow. . Other examples include Plymouth to Gunnislake (which reverse at Bere Alston and used to be a route to Tavistock) and Liskeard to Looe (which reverses at Coombe).
