'Even if there were a High Holborn tube station (note correct spelling) - which there is not - you would have to be deranged, or have overslept, to disembark there (or even Holborn, which does exist) to get to Main Building.
Moreover, the timetabled time from Uxbridge to Holborn is 54 mins - a sensible choice would be Westminster, taking only 52 mins (change at Baker Street from Metropolitan to Jubilee line) then a couple of minutes walk to the South Door.'
Teeteringhead - I thought we were playing Mornington Crescent there for a moment!
