Hi
All your water=* tags require a natural-water tag in order to render correctly.

Tip:

Instead of deleting a current object, only to replaces it, could you use the existing way, in this case a platform, to create the new object. It retains the history of that way which is useful for validation purposes.

Hi
All railway=station in Britain are mapped. Please don't add duplications.
way/134679224#map=19/55.871115/-4.269206

As you're aware there is already a railway=station node.
node/6291570884
There can only be on tag for a station.

Hi
Where did you get details of this path from?
I don't remember there being a gate in the fence.

Yes, one railway=station tag per station but may have multiple building=train_station buildings.

Please refrain from duplicating railway stations, especially as you're aware there is an existing.

Hi
I think you've deleted the more accurate of the duplicating platforms.
At Chancery Lane station they're straight, adjacent to the rail tracks & don't cross over them.

Hi
As mentioned on previous occasions, these are not railway stations. All stations are already mapped.

way/1319278089#map=18/51.149121/1.271850

Or you could have left it alone as it was performed with knowledge.

No, it's a "Test". Still in progress.

Hi
Is this a train station or an office?

Hi
All railway stations are already tagged. Please don't add erroneous data.
way/1317078047#map=18/51.516162/-0.174443

The best way to prevent your edits being reverted is to avoid adding erroneous data to OSM.
Just one example: This is not a platform.
