Questions & Answers about Le départ du train est prévu à huit heures.
Because départ is a noun meaning departure. French often uses a noun phrase where English might prefer a verb.
So this sentence is structured more like:
- The departure of the train is scheduled for eight o’clock
rather than:
- The train leaves at eight o’clock
Both are natural in French, but le départ du train sounds a bit more formal or timetable-like.
