the Kiwi Card - but not where you'd expect

The SNCF, or French National Railways, created the Carte Kiwi in 1987 as a discount card for those with families to travel at half price for up to 4 persons.  It was still in place 10 years later, but we are not sure when it ended.  The video clip with its catchy song (well remembered if not always fondly) here.  For those who don't understand French, here is the transcription:

(Tous) - Kiwiii
(All) - Kiwii
(Papa) - Avec la carte Kiwi, tu payes moitié prix.
- Et ton papa…
(Dad) - With the Kiwi Card you pay half price
- and your dad...
(Tous) - …aussi.
(all) - ...also
(Maman) - Et ta maman…
(mum) - and your mum...
(Tous) - …aussi.
(all) - ...also
(Tonton) - Et ton Tonton…
(Tonton) - and your Tonton
(Tous) - …aussi.
(Marraine) - Et ta Marraine…
(Tous) - …aussi.
