"The definitive map and public rights of way are very much an outdated legal basis"

Rubbish

"with use-it-or-lose-it review upcoming and causing much fuss.

So what?

" previous survey states “they've put a private sign up”

So what?
That doesn't usurp or negate legal right of way.

" in some cases the land owners still reject even that."

So what?

"aking access=private off now means all types of vehicle may travel, "

No.
Because they're all highway=footway

The access refers to the footpath not the land it passes over.
A walker is meant to stick to the path.
Almost all rural PROWs cross private land.

From OSMWiki
access=private - "General public access is not allowed. Access is granted with individual permission only"

From Wikipedia:
"In England and Wales a public footpath is a path on which the public have a legally protected right to travel on foot"

Hi
Welcome to OSM
The footpath is not private.
Are you sure the grass pitches on Lansdown are lit?

No public transport tags are required for entities which aren't public transport.

Unsure what you mean.

Hi
node/9991604554

Miniature/Tourist railways are not public transport. Please don't add erroneous tags just because iD editor suggested it.

Hi
Which format did you download the data in from OS Opendata.

When attaching to waterways did you remap the waterways to suit the boundaries?

Are you sure?

" add it as an additional tag."
No. Duplicating tags of the same meaning leads to errors & confusion.

Hi

Please refrain from adding service=siding to railway tracks which are clearly for passengers trains which stop at platforms allowing passengers to disembark

Are you sure this is a park?
As in seats, playground, lawns, ice cream kiosk etc?

I used some pictures from network rail documents. I've added a note recommending an on the ground survey and if the road to the platform still exists.

The railway station tag already exists.

There is already a railway station.

Hamworthy Train Station railway station already exists.

They're not apartments.
