Six people including a 14-year-old boy died in Lop Buri early Friday morning when a train slammed into a chartered van carrying 14 Songkran holidaymakers from Bangkok to Ubon Ratchathani.
Four other passengers were seriously injured in the 2.45am crash in Pattana Nikhom district at a railway crossing on Highway 3017 three kilometres from Kaeng Sua Ten Train Station.
Rescue workers had to extract several deceased victims as well as the injured from the van.
Pol Colonel Krir Saengpol said the van sped in front of the Nong Khai-Bangkok train and was broadsided and flung against a concrete barrier, instantly killing two male passengers aged 28 and 60 and two women aged 18 and 28.
The 14-year-old and a 41-year old man died later at hospital.
The van driver and four passengers suffered minor injuries. Police planned to question the driver later.
