@matt_ellery surprisingly it is OsmAnd

Thanks for that insight. It is indeed a designated 'footpath' in the PROW sense. However routing software does route cycles along this path. It does not seem to along other paths in the vacinity. The route itself is muddy and steep and would be generally treacherous on a cycle, apart from the leading you to two steep flights of steps.

Thanks. I have made those changes, but it is still not displaying correctly. I wanted the new building to 'appear' but it seems to be obscured by other layers. All I am seeing is a triangle that I think is the bottom right (SE) corner.
Thanks, Graham

Thanks for that clarification @matt_twam_asi. Guys, is that enough to update the classification of these ways?

If you follow route 223 (DownsLink) around the station some of the segments are not designated "bicycle" at all or as "bicycles" in the "allowed access" table. Is that the problem?

Thanks, that's perfectly OK. Perhaps there is a better way to flag this point as a problem for some experienced person to investigate.

There appeared to be a problem with routing along the DownsLink north of Christ's Hospital station. I was accessing via ridewithgps.com and it takes a long detour off the track by road. It behaves like there is a break in the track.
