The rules are rather involved now.

A similar situation applies to Cheshunt. You can travel there at any
time using a Freedom Pass but only on London Overground trains that
run via Seven Sisters. You cannot travel to / from Cheshunt on a
Greater Anglia train at any time regardless of the route their train
takes. Similarly you cannot use a Freedom Pass north of Enfield Lock
on the Greater Anglia services that run via Tottenham Hale.

And on the route between Harrow & Wealdstone and Clapham
Junction it's only a Disabled Pass which is allowed on a
Southern train before 09:00 weekdays.

Exactly. For all sorts of historical reasons, the rules are
complicated, and they're not displayed on station posters. If the full
set of rules were on posters, the font would have to be so small, that
Freedom Pass would complain that they couldn't read them.
