1 Present Simple – Public Transport Timetables

• Usage: We always use the Present Simple for official schedules, timetables, and itineraries (buses, trains, flights, ferries, movies). We use it even if the departure is in the future (tonight, tomorrow, next week).
• Formula: Subject + Verb(s/es) OR Subject + doesn’t + Verb(base).
• Example: The train leaves at 8 PM. (Because it is an official timetable).

2 Future Simple with ‘Will’ – Spontaneous Reactions

• Usage: When you look at the schedule and realize you are late, you must make a quick, new decision. Use ‘Will’ for decisions made at the exact moment of speaking.
• Formula: Subject + will + Verb(base form).
• Example: We missed the train! I will call a taxi. (This is your spontaneous alternative plan).

3 Common Traps to Avoid

• Do not use “will” for public transport schedules just because it happens later today. (Incorrect: The bus will leave in 5 minutes. -> Correct: The bus leaves in 5 minutes.)
• Do not use Present Simple to state what your new plan is. (Incorrect: I am late, I take an Uber. -> Correct: I am late, I will take an Uber.)
• Never use “to” or “-ing” after “will”. (Incorrect: will to buy / will buying. -> Correct: will buy.)
