Department of Rail Transport Orders 100% Drug and Alcohol Tests for Rail Staff Following Fatal Crash

Brickinfo News Agency – The Department of Rail Transport (DRT) has issued an urgent directive enforcing 100% drug and alcohol screenings for all train drivers and safety-related personnel. This immediate safety measure follows a fatal train crash at the Asoke-Dindaeng railway crossing in Bangkok, which resulted in eight deaths and 30 injuries after a cargo train collided with a public bus and multiple vehicles. Subsequent police tests revealed that the train driver tested positive for illegal substances.

The directive, issued on May 17, 2026, mandates that the State Railway of Thailand (SRT) implement a Zero Tolerance policy. Under this new rule, all operating staff, including train drivers, traffic controllers, and ground personnel such as track switchers and crossing keepers, must undergo strict screening before starting every shift. DRT Director-General Pichet Kunathammaraks emphasized that the measure aims to restore public confidence and guarantee the highest safety standards for both rail passengers and road users.

Regarding the specific incident, the driver of the cargo train, identified as Sayomporn Sonkul, was found to be operating without a valid rail personnel license from the DRT. Following the discovery, the driver was immediately suspended from duty. Mr. Kunathammaraks confirmed that the SRT has been ordered to launch a severe disciplinary investigation and pursue maximum legal action against the driver and the crossing guards involved. Furthermore, an in-depth probe will examine how supervisors permitted an impaired employee to operate a locomotive.

The enforcement aligns with existing legal frameworks aimed at ensuring transport safety. Mr. Kunathammaraks cited Section 90 of the Rail Transport Act B.E. 2568 (2025), stating:

“In cases where there is reason to believe that any duty officer has substances in their body resulting from the consumption of alcohol, other intoxicants, narcotics, or psychotropic substances, rail transport inspectors are authorized to test or order a test to determine the presence of such substances. The methods of testing shall comply with the rules and procedures prescribed in the regulations announced by the Director-General.”

The DRT is currently in the process of finalizing and issuing the official regulations to fully enforce this law. The department reiterated its commitment to preventing similar tragedies and ensuring accountability across all levels of rail operations.
