You usually arrive at the airport 60-90 minutes before a flight, vs 30 minutes before a train. And train station locations will give you a 30 minute advantage over airport locations. So really we're comparing 3.5-4.5 hrs for a flight vs 6.5 hours for a train. Trains are also a lot more comfortable, have charging points even in economy class, and don't charge baggage fees.
