we plan to travel from Hangzhou to Chongqing in Nov. We would like to see some natural scenaries during transit to Chongqing, but we won't have enough time to do a Yangtze cruise from Yichange to Chongqing. Is the scenary on the train route from Hangzhou to Chongquing worth the extra travel time, or are we better off going by air?

I found Train No.: K425/K428 going from Hangzhou to Chongqing. does it mean we need to change train, if so where/station do we need to change the train? how long do we have to wait for the train change?

is/are there direct trains from Hangzhou to Chongqing, and what train number (s)? any information you can provide will be greatly appreciated. Nancy
