I will be arriving at Heathrow Terminal 3. I know the pros and cons about pricing/timing/luggage/accessibility issues/etc. among the various transportation options between the airport and the heart of London.
Here's what I am wanting to know:
After arriving at the bottom of the stairs on the basement level in Terminal 3, do the walkways branch off with one going to the Tube/Underground station and a different walkway going to the Heathrow Express platforms?
When walking to the Heathrow Express platforms, do you pass a ticket counter and/or ticket machine where you can top up an Oyster card?
Thanks in advance for any help on this topic.
