Hongkong to Guangzhou by train.

From Hkg Nathan Road,Tsim Sha Tsui, we want to go Guangzhou by train. Is the train station far from our hotel? How can we get there? If we go by taxi to the train station, how much does it cost? How much the ticket to Guangzhou and how long does it take?

Is the Guangzhou railway station is not far from the bus station, just want to know as we also want to go to Zhuhai-Gongbei by bus. Wait for yr info, thanks n rgds
