I'd have thought that the easterly connections with Crossrail, linking
with the current Thameslink services would provide most of the
inner-suburban connectivity for such a route, and the number of people
going between far Essex and East Anglia and Sussex, for whom an extra
connection is offputting are few in number.

To build on the last-mentioned point, surely a lot of air travellers
from Essex & East Anglia would be better off going from Stansted
rather than Gatwick?
