It's not the industry standard though (which is Darwin). My experience seems to suggest Google/Apple Maps has the base data in it and this is poor at dealing with alterations to the timetable, particularly things like platform changes.
I've known & seen station staff to regularly end up in weird disputes with passengers who are heading to a clearly empty platform adamantly pointing at Google Maps on their phone with the platform number on it, despite the fact its either a) not been advertised or b) altered long in advance.
