Das wäre aber viel Arbeit! Vielleicht mache ich mich noch einmal daran.

Have you discussed this mechanical edit? If not it must be reverted since the Wiki is clear about this: power=sub_station

Hi InfosReseaux,

your changeset seems to be an mechanical edit: osm.wiki/Automated_edits

Have you announced this retagging in before?

Hi kriscarle,

have you broken this node: node/1080341965 ?

Best regards

Hi Mr. Ryan,

please make sure, that you don't accidentally shift other points. This has happened to the [railway crossing](node/82706674).
I can recommend the JOSM editor (https://josm.openstreetmap.de) for more sophisticated editing tasks.

Best regards
