K-train from Xiamen Gaoqi train station

I want to take the K572 to Beijing West. I found the route on this site. However, I don't know if the K572 leaves from Gaoqi trainstation or the North Station. It just says 'Xiamen'. I thought the station on the island (Gaoqi) is under construction, so no trains will depart from Gaoqi. Therefore the train must be leaving from the North Station.

Am I thinking right? Or does the train depart from Gaoqi?

Thanks in advance!
