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

Hi
Tip:
way/246478779
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 these are more accurately described as chokers not chicanes.

Hi
Where did you obtain the maxpeed info for this road?

Hi
please don't change Wikipedia (or other) tags to pages that don't exsit.

Have a look at this:

Plus a few youtube videos

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 mapped in OSM.

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.

The platform_edge tag is a prime example of a solution looking for a problem.

"Split the road into two ways if the angle is actually an intersection."

This is fake. Splitting makes no difference.

Just because it suggests to make amendments it doesn't mean it should.
