Train Tickets from Ningbo to Wuhan

Hello,
We wanted to book a ticket from Ningbo to Wuhan ( Wuchang) on Wednesday. But this is obviously not possible, because its not 6 days till Wednesday, but 5. Is there a possibility to book the ticket via internet? Because we don't know how to get the ticket and we can't go later, because we have booked a ship from Wuhan.
