On: New Tube for London

Where was that? Most shinkansen platforms I've been on were in the open air.

(Also, London has had platform edge doors for a while already - only on half of one line, but still)

Not sure... one of the Tokyo stations I think. It was still an open air platform, but had doors on the edge of the platform around man-height that aligned with the train doors.
