Remember:

We use the future simple (will + infinitive) when we talk about TIMETABLES

e.g. The lecture on genetics will begin at 9.00  .    (is going to begin)

e.g. The show will end at 10 o’clock.  (is going to end)

e.g. The train is late. It will arrive at 6 o’clock.  (is going to arrive)

e.g. The doctor will visit his patients at 5.00. (is going to visit)
