There is a fast way along the travelator tube between T1 and T2, even if the travelator itself is u/s.
Get a trolley, put something heavy on the front (a flight case is ideal), get a good running start and ride the handlebars. You can get a good turn of spped out of those things, and it's more fun than the travelators.
Of course, it gets a litle embarrassing in full uniform, so it's worth keeping your raincoat on, and borrowing a hat from your major competitor...
