Hi
Please don't add 'Platform' to the ref tag, it should just be the number/letter.

Hi
You've attached the Southern end of this platform to the railway line:
way/28929703

You've unnecessarily split a bridge & subway in two,

way/1257815532

way/1257815533

https://nrenner.github.io/achavi/?changeset=148249796

Hi
You've left a duplicate undeleted. it has relations attached which will require transferring.

way/140777120

Hi
Are these stations open to the public?

Hi
The platforms were fine as they were.
You unnecessarily split each platform, when in reality they pass under the roof.
You've also unnecessarily added duplicating platforms as liner ways.

Please revert all relevant changesets.

Please add more descriptive changeset comments than "edits".

Hi Please don't remove area tags from platforms as there's a bug in OSM-Carto which can prevent it from rendering correctly.

Hi
Welcome to OSM.
FYI there was already a railway=station object.. I've made appropriate amendments to the train station building & node.
changeset/151391310

Aargh... I made the poor assumption that the incorrect key held the incorrect value, but it appears "326/4" is the correct value & "Radley FP 4" is the made up one. Will revert & redo.

OSM should /not/ be making up their own. RW, or you, wouldn't dream of altering the refs for motorways or A roads, so it's beyond comprehension why you perceive it to be acceptable for PROWs.

Hi
Welcome to OSM.

There is already a railway=station tag.
railway=stop is the valid tag.

Hi
I really think there should only be one prow_ref tag. Duplicating only causes more confusion.
Looking at Cornwall's database it's clear the values you added to the 'official' tag are the correct ones & should be transferred to 'prow_ref'

Please don't change the well used & documented prow_ref tag to prow_ref:official

or destination even?

hgv designated?

Hi
way/1279782238
You can't have tunnels & bridges.

layer is a rendering tag. the bridge has +1 value so the path doesn't require a layer tag.

Could you provide details of the railway building being under construction? I can find no record of it.

There is already a railway station tag here. Please don't add duplicates.

If you're "Not familiar" with specific problems highlighted by notes then it's best they're left alone.

Hi
node/6135938648/history
Why have you revalued the network tags of some railway stations from Overground to National Rail.

Hi
To check, are you sure about the bin?
The one on the bridge & one next to the path are already tagged
