Just wondering what happens if you use an Oyster Pre-Pay to get on at
(say) Heathrow, and get off at Olympia. There's no Yellow pad at
Olympia so how can you "touch out". Do you get a 1-6 ticket?

Also what does a ticket from North Acton to West Kensington cost? Is
it a 2-3-2 Journey (Via Ealing), or a 2-1-2 journey (via Notting
Hill/Earls Court).
