In fact the only ticket that appears to exist that would be valid on

valid ticket - they are supposed to charge you the full walk-on
standard fare...)

I remember reading that KO was a "London Terminal", precisely for
trains taking this route. Is that not right?

It's not a London Terminal. (Apparently it used to be, though.)
