Fast Train options to/from Milan are not showing between Aug 5th and Aug 18th. Are these two weeks some kind of maintenance week for fast train? Normally Milan to Rome is 3 hours, on 5th Aug it becomes 6 hours and on 7th Aug is 9-11 hours on non-rapid train- this stays like this till 18th August. If schedule is not released, why is it 19th August onwards tickets are again available for rapid train?
