How exactly does a rail link between LHR and LGW increase *air*
capacity? The problem at Heathrow is said to be that the runways are
98% fully used. Gatwick is already the world's busiest single-runway
airport. So how is this capacity increase achieved?

Bigger planes at Gatwick (they see this as a way to increase from
roughly 32m to 40m pax a year). And their "single runway agreement"
expires in 2019.
