Hat Yai Junction railway station

The front facade of the station building in 2009.

The original station was known as U-Taphao Junction and was located to the north of the current station. The U-Taphao station also served as a junction for the Hat Yai–Songkhla Line. However, the junction often got hit by floods and was moved to the present location at Hat Yai Junction. U-Tapao was reduced to a halt and eventually closed. In 1978, the line from Hat Yai to Songkhla City closed down, leaving the junction to be only for the mainline to Sungai-Kolok and the branch to Butterworth.

Since the start of 2013, there have been plans to rebuild the line back to Songkhla City.
