1. Is the £3.00 single (to U23) as issued at Olympia when pressing the
'Wimbledon' button on the machine actually valid on NR via Clapham
Junction? And, if not, why does the button not say 'via Earls Court'?
What would the penalty be if ticket checked on-train?

If Kensington Olympia and Wimbledon are treated as "joint stations"
(i.e. a joint LU/National Rail station), then LU pricing applies, ditto
if you use the tube all the way.

I've not met this concept before. Are you saying that a tube Z23
single is valid from KO to Wimbledon on NR?
