Hi
To check, is it meant to be this shape?

You added the tag which defines a railway station (railway=station) to the building, This is incorrect.

I've corrected it for you.

All UK railway stations already are mapped. Please don't add duplicates.

Please don't delete tags without understanding why.

What is this?

Hi
Could you refrain from duplicating tags (ref:crs) on relations which are already on ways & nodes. It only causes confusion & errors.

When detaching railway=station tags from railway lines could you move them instead of deleting & recreating anew. The edited history of data is very useful.

Unsure if you're adding them, but entities such as railway lines, ATMs. bike racks, bus stops, cafes etc aren't required. (Actually I think there's a fair argument stop areas & PTv2 isn't required at all. It's all just duplication & collections.)

Hi
Could you delete the school tags & move it back to where it was previously please. There is already a school mapped as a polygon way.

Have a look at this to see how to tag recycled phone boxes

Hi
There is already a railway=station tag.
GB stations are all mapped (as nodes).

Great.

Ah, OK. I don't remember it going that way, but it was a few years a go.
Do you want to update it, putting the gates in?

Sorry, which path?

I'm pretty sure this isn't the train station building. Could it be the surrounding one?

Hi
You've added another duplicate railway station which I've now deleted.
node/7831821811

Please be aware all UK stations are already mapped. You can often find the node between the tracks at the midpoint of the platforms.

You made it inaccurate again. These are not a public_transport=station.

node/3913898919

Hi
You've created two duplicate stations:
node/3913898919#map=18/53.68227/-1.50551
node/26152985#map=18/53.68230/-1.50536

Does QEW (west) still have shared pavements?

Sorry for the delay.
Surface tags can be added to the crossing nodes.
If the highway was mapped as a polygon, showing explicit width, then the crossings should be mapped linearly & I'd have removed the nodes.

Hi
I assume this is meant to be something other than a station?
node/7805862411#map=19/52.35844/-1.87426

Please hold steady.
Your edits are duplicating data. ie There is an existing track here: way/835776031#map=16/53.5706/-2.4225
And there are two station nodes. Please revert this changeset

PS Level=0 is redundant as objects without it are assumed to be at that level.
