Why use "c'était" when referring to the TGV?

Question

It seems it should be "il était" because you are referring specifically to the TGV, and not trains generally.

Accepted Answer

Hi Ken,
In, ‘ C’était très rapide’ what is meant is the whole journey rather than the train itself which of course is very fast....
Hope this helps!

Answer

pourquoi on utilise « rapide » au lieu de
« rapid » ? je pense Le TGV est masculine.

Answer

Hi Lixin,
Le TGV is masculine but the adjective 'rapide' always has an -e whether the noun it refers to is masculine or feminine.
Une réponse rapide = a rapid answer
Un message rapide = a rapid message
C'était rapide = It was rapid
