I've undone the deletions and made what I hope are all the needed updates and corrections. I made the entrance way from the south a service road (as there are other properties as well as the farm), the tracks that don't carry public footpaths access=private with gates where I can see them (eg to N ), and all the public footpaths are set as foot=designated, designation=public_footpath on footways and same with vehicle=private where the public footpath is carried by a track. I put the path behind the first hedge at the immediate east of the farmyard. Also had a go at updating the new housing 'Paddock Green' as far as known. Have a good look at see if anything needs further adjustment, and you can retry changing and/or comment here.

wrong, reset main line of A6 to trunk

I could say the same about every church and street - all St + name, not as you changed 100+ to Saint

This substation is in a private housing area, gated, private access. Unless you copied the name from a database?

Certainly: read osm.wiki/Relations_are_not_categories
Also read the discussion with you from 2 months ago at changeset/171884705
This relation, as created by you (and the next 60 versions modified by you) is about 0% complete of the coverage of the UK its name proposes. How many more versions are required to complete it and maintain it? Noone else is going to waste their time helping with this.
You can get all the substations in any required geographical area with an Overpass Turbo query, filter at will on voltage, operator etc according to the tags available, and it is automatically completely up to date with everyone in the OSM community helping.

This changeset changed the access for motor vehicles on way
way/461119575
as if the restriction sign (bus + taxi, bicycle and motorbike only 7am to 7pm) had been removed, but leaving the conditional restriction tags in place. Which is it? sign still there (tagging was correct as it was) or sign removed (conditional restriction needs deleting) ?
Please respond to changeset comments
