Do you remember the horror of the liquid-gas truck explosion more than a decade ago at New Phetburi Road’s express highway entrance? That led to more attention being paid to preventing a similar accident. Do you remember the locomotive that ran right into Hua Lamphong station’s platform and ticketing area only a few years ago? We have not stopped transporting volatile liquid gas by truck, nor have we stopped using locomotives or Hua Lamphong station, so why worry about the subway?
