text: The OSM https://www.openstreetmap.org/relation/6474994 bypasses the station, and that seems to correspond to http://content.tfl.gov.uk/capital-ring-section-12.pdf
  
  But there is a note "The route now passes the skateboard track of Crouch Hill Community Centre. There is a link here to 
  Crouch Hill station". So, it looks like that's a detour rather than the actual route.
