Where this comes from

From the map
The name, the kind of place, the address where the record carries one, and any website, phone or opening hours shown as recorded on the map are tags on OpenStreetMap node/448606595, and can be corrected there.
Worked out here
Every distance, the nearest road where the record has no address, which car park and which stop are nearest, and the order of the lists are this site’s own calculations from those records. Distances are straight lines between two points, not walks along the footpaths, and the map will route the real walk on request. A mistake in any of this is a mistake here rather than on the map.
