This is quite clearly *not* a permitted route on a Watford Junction to
London Terminals Season ticket, as the *ONLY* map listed is LM, which
does feature Clapham Junction, but not Vauxhall.

It doesn't need to feature Vauxhall.

Clapham Junction is (in this case) the Routeing Point for Vauxhall.
Mapped routes are determined by: shortest route from origin to origin
RP + route from origin RP to destination RP traced out on map(s) +
shortest route from destination RP to destination.
