(If you were to somehow escape Waterloo Tube station without touching-out,
and get on to the Waterloo mainline platforms without touching-in, then on
arrival at Wimbledon the system would assume you'd arrived on the
Underground - of course you would also have made the Waterloo to Wimbledon
journey on SWT without a valid ticket.)

Suppose you touch in at Kensington Olympia and touch out at Wimbledon. Does
the system know whether you've used LUL throughout, via Earls Court, or NR
throughout, via Clapham Junction? Does it take account of the day/time and
whether the Kensington Olympia - Earls Court service is actually running?
