For timetables we use the simple present. Read the explanations.

When we talk about timetables we use the simple present, because a timetable is true in the future, but it is also true in the present.

- The train for London leaves at 9:00 (every day)
- Classes start on September 10th
- The shops open at 9:30 and close at 5:00

We also use the simple present with a future meaning in most subordinate clauses (a subordinate clause is the part of a compound sentence that goes after the connector). We use WILL in the main clause, but simple present in the subordinate clause:

- I will be there before you arrive.
main clause = "I will be there"
subordinate clause = "before you arrive"  (no WILL)
In some languages they use WILL in the main clause and in the subordinate clause, so if your language is like that, be careful.

- I will go to Madrid tomorrow. When I go to Madrid, I will phone you.   (we can't say: when I will go to Madrid)
- You will come and I will help you.
- If you come, I will help you.
- Will you stay here until the plain takes off?
- I'll go where you go
