They're obvious from aerial imagery, although it may not always be apparent what type of way they enclose. Mapping the paths of former railways indicates what those ways were (although it's possible that some sections may have been repurposed as roads, cycleways or footpaths). I didn't add this former railway, but I've tweaked it. https://www.openstreetmap.org/way/31982354#map=14/52.0675/-4.6421 In the area shown, from Cardigan to Cilgerran it is part of National Cycle Route 82. Part of that is also the access road from Cilgerran to the Welsh Wildlife Centre. These are well documented as following the route of the former railway. I've only mapped the hedges lining the route at the Cardigan end, but they're apparent elsewhere along the route.

I'm not sure that I would map a razed railway line where no trace of any of it remains. I'm not sure if I would map a short section of line that has been built over and no trace remains if there were clear traces of the rest of it, but I wouldn't remove it if somebody else had mapped it. and it is tricky to distinguish case of "person is representing silent > mappers not participating in discussion" and "person has fringe opinion > not shared by anybody"). > We don't have humming. The best we can do is note that several people have expressed differing opinions and that the matter is contentious. We can also note that certain edge cases have been highlighted. I'm with Volker on this one: at this point in the conversation it is unhelpful for the wiki to be changed to state that these things should be removed whenever they are discovered. -- Paul
