If it takes me 2 minutes to walk over that bridge (say), unless I'm
injured I know it will always take that.

It's much more than 2 minutes.

It's about 200m long, and has travelators, so two minutes is about right.

What about the escalators up and down?

OK, so add another minute.

They are extremely long escalators.

Not compared to the ones down to the Heathrow T5 transit or the T2
walkways:
