Hi, it looks like railway lines Way: 580907944 and Way: 580907943 have been dismantled. Thus not active sidings as you've indicated. Ought they to be tagged railway=dismantled?
Regards Bernard

Hello, you've actually duplicated long parts of the miniature railway and it's also been joined in places to the abandoned railway. If the abandoned and the miniature railway occupy the same line then there should only be one line feature. If you need any help please just ask.

Hello and Welcome to OpenStreetMap.
Does HRTA replace Chic Unique, they are both hair salons at the same address? If so then the original POI ought to have been updated in order to keep OSM history intact. Certainly there should not be two POI for the same salon.
Also a problem is that the manner of tagging is not to OSM best practice (open hours especially). There's lots of advice online and if I can help please just ask.
Your response is awaited Regards Bernard

Hi, no need to add the tag oneway=no to indicate a two way highway. In the absence of a oneway=yes tag, it is taken by renderers to mean a two way highway.

Hi I've placed the woods details on the woods outline.

Hello and Welcome to OpenStreetMap.
Both of your new POI's are already mapped, 100 club as a POI node (Node: 100 Club (313349354), Koko's as a building (Way: Koko (225465155). Both are fully tagged/described so the new items are duplication and ought be removed. I can remove them if you wish.
Regards Bernard.

Hello and Welcome to OpenStreetMap.
The data contained on your two POI is already contained on the buildings outline. Thus the new information is a duplication and not needed. I don't think you can remove the POI with GoMap so I've removed them for you.

Hello and Welcome to OpenStreetMap.
It seems odd that you give so little information to help others find this place, an address would be helpful.
Is this feature verifiable should others visit? If not it ought be removed.

No response so junction removed.

Hi, you've added a new service road to this feature (G3 South Multi-Storey Carpark (578643437, v2)), It looks like it's joining ground and roof ways. With no levels indicated on the ways this seems to be incorrect. There must be internal ways between the ground level entrance and the roof level ways. Could you please indicate the way levels?

Hello and Welcome to OpenStreetMap.
The pub building is already mapped and it is OSM practice to where possible tag an area/building. (A second feature/POI is then duplication.) Thus I've added more info and placed it all on the building outline.

Hi and Welcome to OpenStreetMap.
There was already mapped a POI for the dentist so I've amalgamated all data onto one POI. I added amenity=dentist and adjusted the opening hours to OSM practice.
I see the phone number differs from that on the website. Actually the webpage and facebook phone numbers differ, could you check and rectify if necessary please?
Regards Bernard.

Hi, could you check Way: 571062876 http://tools.geofabrik.de/osmi/?view=geometry&lon=-5.70342&lat=50.06261&zoom=18&overlays=self_intersection_ways,self_intersection_points,single_node_in_way,duplicate_node_in_way
pretty sure it's accidentally mapped.

Hello and Welcome to OpenStreetMap.
Your car park POI are mostly a duplication of data that is already contained on the car park outlines. I've added any new data from your POI to the outlines plus some new data.

Hi, a water feature does not have to have the tag natural=water unless of course it is a natural feature. The database recognises a dock as being water.

Hello and welcome to OpenStreetMap.
You mapped both the building and a poi as the community centre duplicating information. I've placed the POI info onto the building outline.

Hi, pub name corrected and added web and Instagram contact.
