BAA don't want ticket gates for their platforms at Heathrow, though this
might not be a problem if TfL (and their customers) were prepared to
accept increased charges for unresolved journeys, in case they ended at
Heathrow Connect. More to the point, can TfL come up with a method of
using Oyster PAYG as far as Hayes & Harlington then a paper ticket on to
Heathrow. How does a passenger touch out while staying on the train at
Hayes & Harlington?

Why do they have to have gates? What's wrong with a few validators? It's
what they on DLR and much of National Rail anyway.
