There is no need for T6 without R3. The current construction work at LHR is all about aligning everything with the East/West runways rather than around the old star shaped system.
Can't we forget any Manchester talk now and keep this thread about turning the UK's premium airport into a major hub? The customers are already waiting, we don't need to worry about that. The money is waiting to be invested we have no issues there.
It really should be a no brainer and I am only glad the nimby's never had as much power in the days of the railway boom or the construction of the motorway network or we would be well and truly scuppered.
