Hi
I'm still struggling to comprehend this as valid bus stop.
Do you have links to online timetables & databases for the specific service you mention?
Are you able to upload the CORPUS data to, say, Dropbox?
The route is oneway so I'm unsure the service you state, runs to this stop. In fact I'm struggling to find an route which uses it.
The stop would be on the other side of the road as buses have left sided doors.
I'm unable to locate any Govia services, only Arriva & Centrebus.
I can not locate the stop on Google Streetview.

Please check to see if there is already a railway station tag
node/486585551

Are you aware you've put buildings on top of others?

"Work in progress"

Hi
When adding nodes with OSMAnd please check to see if there are polygon already existing:
way/39313868

building=train_station is a valid tag to represent station buildings of which the can be many. There can only be one railway=station tag per railway station.

station buildings can be a good distance from where passenger catch a train so should not include railway=station tags..

railway=platform denotes actual platforms as can be seen here.

It appears you're mistaken & confused by PTv2 schema.

It's not a platform.

You'll note I amended the building to 'train_station' & removed the duplicating tag.

Hi

way/779270017

There is already a railway station:
node/3715250479

Hi
You appear to have duplicated biuildings
way/550018977#map=19/51.23753/-0.19197

There's still two very short lengths without the NCN relations. Unsure if they have any significance.: One of them: way/759989733

Hi
It becomes "complex" if tags are duplicated in irrelevant locations.
You added a stop area relation. Therefore any routing software will be able to find the ref:crs on the station node.
Adding duplicating data only leads to confusion & errors.
One station = one station code.

Please add railway=stop + the relevant NapTAN stop position codes to enable accurate routing.

Those are all railway codes. Why have you added it to a bus stop (that's nowhere near a railway)? Are you reading old data for the station on the former line that is now a busway?

Hi again
Where did you obtain the ref:crs tag from?

Hi
Where did you obtain the ref:CRS tag from?

Hi
What has Network Rail data to do with bus stops?

Great, thanks.

Has this building been removed?

Adding superfluous ref:crs tags "skews the data" . In this instance - for the router.

Cheers
