Train driver's errors and lack of license cited in fatal collision

The train driver, who later tested positive for drugs, had also not received a valid operator’s licence from the Department of Rail Transport.

The ferocity of the blaze was such that the remains of several victims are still awaiting full forensic identification. The collision was captured on CCTV.

Authorities were quick to attribute the crash to human error. The driver, identified as Sayomporn Sonkul, ignored a red flag from a trackside guard, who officials said also appeared slow to lower the level-crossing barrier, allowing the orange city bus to become stranded on the tracks.
