Thank you for your reply Mr Thom,

I would like to know whether it's possible to buy the train tickets on the same day as the arrival date, 12th Sept for departure from Hongqiao railway station as we'll arrive in Hongqiao airport by mid day.

Am I correct that Hongqiao railway station is located in the same building as Hongqiao airport?

Will we also be able to purchase train tickets from Suzhou to Hangzhou at the same railway station on same day?

Many thanks in advance,
