For example, I can see a station is missing, but is there any way to find its UIC code (or other identifiers) so I can add an entry? It's not clear what `is_suggestable` actually means, so I wouldn't know what to input.
Also, while there are info:* columns for miscellaneous info, there doesn't seem to be multiple name:* columns for the localised station name (a lot of this data may already be in OpenStreetMap)?
