This railway line https://www.openstreetmap.org/way/169017689 is part of the Cherwell Valley Line relation https://www.openstreetmap.org/relation/193007 but it's not covered by the red line in the route map in the Wikipedia article https://en.wikipedia.org/wiki/en:Cherwell%20Valley%20line?uselang=en-GB - should it be in the relation?  If so, should the westbound tracks https://www.openstreetmap.org/way/509593722 also be in the relation?
