Pak Tho police reported the incident happened at 10.20 am near Bo Takrow railway crossing in Tambon Bo Kradarn between the Sugnai Kolok rapid train from Sungai Kolok to Bangkok and the container truck.
The driver identified as Prawit saw Ton, 53, was driving on the Bo Takow- Bo Kradarn road and was approaching an unmanned railway crossing.
The train was also arriving near the crossing.
Witnesses said the driver drove on to the crossing trying to avoid a concrete railway signboard blocking his sight, the head of his truck was already jumped on the tracks at the same time as the train approached.
The truck was rammed on the head by the speedy train killing the driver and seriously injured the woman who came with him.
The crash, however, did not derail the train but cause a 15-minute delay when it has to await railway workers to clear the badly damaged truck from the tracks.
Villagers said the sign board was erected close to the crossing and obstruct the sighting of the train. Therefore drivers had to drive close to the tracks to get clearer view of whether there is any oncoming trains. To do this the front part of the vehicles will be on the tracks already.
