luxury train is not my choice, but a train fare which is just between air fare and luxury train fare with the speed over 150-180+ mph(about 200-300+ km/h) would be my choice if time matter. if I happen to travel to india by the time that the bullet train was on service there, I'd definitely choose bullet train service. I think the bullet train service in japan (often called shinkansen) are the most on time, usually late departure but arrive early within sec to minute. just 515km of distance between 2 cities, it already connected just within 2 hour with the speed of 186 mph.
