 It can be seen that rail travel takes a long time, even the bullet types take more than 12 hours, so if you are pressed for time, flight will be a good choice and it only takes 3 hours for the whole journey. Of course, there are some disadvantages for flight travel such as it will be easily affected by weather. Also, flight travel will cost more than rail travel, even in low season.
