Part of the attraction of the scheme is not having to queue up to buy
tickets (and also not needing to know the system well enough, including
speaking English, to be able to decide which tickets to buy).

So you'd pay twice as much

Where's this "twice as much" come from?

not to queue up, would you?

Have you seen the queues at St Pancras?

Ah, here we are.. taken soon after it opened; the queues in the
foreground are for the machines, and in the mid-distance the zig-zag
queue for the windows. Not sure what's going on beyond the xmas tree.
