Of the 15 Glasgow Subway stations 9 have island platforms, 3 have
standard facing platforms and 3 have a sort of compromise where a
standard platform faces the glass wall on one side of an 'island'
platform - easier seen than explained - as here at Buchanan Street,
photographed on 16 October from the Inner Circle platform with the Outer visible through the glass. If the idea is to save space (you work it out) while having safer, separate platforms then it doesn't seem to have caught on elsewhere.
