These rail lines are not sidings. They carry freight/passenger traffic & stop to (dis)embark.

Hi
way/166353896#map=18/51.865928/0.166033
This is not a siding as it's used by passenger trains to (dis)embark passengers.

You're correct. Now fixed.

Oldbury and Bromford Lane Railway Station was a different railway station.

There is already a train station tag.

Stop making crap edits.

Refrain from making edits of which yo have no understanding.

Welcome to OSM
The train station's network & operator are correctly tagged and there's no need for a linear platform when the polygonal one exists.

Strawberry Line is the name of a route which traverses along this path.
There are numerous routes traversing along this path, therefore the name shouldn't be on the way, but in it relation.

node/3729401291/history/18#map=19/51.511250/-0.056924
operator is classed as London Overground not Transport for London

Provide more informative descriptions than "I have made the validator happy."

Hi What is ref:GB:HER:Angus?

There si already a railway=station tag. Please don't duplicate.

None of the tags, except a link to the other database are erroneous. OSM isn't a database dumb.

"There should be only one railway=station element for each station (refer to One feature, one OSM element)".
railway=station
