Which is the railway station to get a midnight train from GuangZhou to Wuhan

The last train from GZ to Wuhan is around 23:53 from Canton Railway Station.
From the airport, you can take the airport express line 1 to reach Civial Aviation Ticket Office in about an hour. The ticket office is near the local railway station. Then you can walk to reach the railway station easily.

My flight arrive at 21:30. Did i have enough time to catch the train ?
Is there any link here that proves the airport directional plan/map ?

Thanks

Hi, time may be a little tight. But if you hurry up, you may catch that. To save time, you'd better buy the train ticket in advance and check in upon your arrival there.

As for the airport directional maps, you may download at this website:

Besides, the guiding signs in the airport can very clear.
