Hi
'Ticket office' is not it's given name. Please revert.
Add facilities as nodes within the building:

shop=ticket

amenity=vending_machine

Please don't delete valid data (ref:crs from railway station tags)

Please don't add railway=station to train station buildings
"It should be mapped separately from the railway=station tag as they may have different names.

There may be multiple train station buildings per railway station "

building=train_station

Hi
Please use train_station instead of railway_station.
building=train_station

What do these represent? railway=yes is vague. There's already a railway=station tag. Wouldn't the info be better on that node?
