Train Driver Who Crashed Into Bangkok Bus Tests Positive For Drugs

BANGKOK — The horrific train and passenger bus collision that tore through a busy railway crossing in central Bangkok on Saturday afternoon has taken a shocking turn. Thai police have revealed that the driver of the freight train tested positive for drugs, adding a layer of criminal negligence to a tragedy that has left eight people dead and over 30 injured.

The accident, which saw a heavy freight train slam into a stationary public bus and spark a massive inferno, has ignited widespread outrage and prompted urgent calls for a sweeping overhaul of Thailand’s railway safety protocols. As families mourn the sudden loss of their loved ones, authorities are piecing together the final moments before the crash, revealing a chain of preventable human errors.

Following the devastating crash, investigators ordered immediate drug and alcohol testing for all railway personnel involved. According to local police chiefs, a preliminary urine test on the train driver returned a positive result for illicit substances.

The driver, who was also injured in the collision and is currently receiving medical treatment under police guard, has been formally charged with negligence causing death and serious injury. Authorities have stated that further charges are pending as the investigation unfolds.

“The train driver has been charged with negligence causing death, as evidence clearly indicates reckless conduct leading to fatalities,” said Urumporn Koondejsumrit, the head of the local Makkasan Police Station, in a statement to the press. The discovery of intoxication has shifted the focus of the investigation away from a potential mechanical failure and placed it squarely on human error and gross negligence.

Black Box Data Reveals Tragic Final Moments

In the immediate aftermath of the crash, the State Railway of Thailand (SRT) recovered the locomotive’s data recorder—commonly known as the “black box“—to analyze the train’s speed and braking telemetry. The preliminary findings paint a grim picture of the seconds leading up to the disaster.

Data shows that the freight train, which was hauling heavily loaded containers from Chachoengsao Province to the Bang Sue junction, was traveling at approximately 35 kilometers per hour (about 22 mph) as it approached the busy crossing.

Crucially, the black box revealed that the train’s emergency braking system was activated a mere 100 meters before the point of impact. Railway experts note that a freight train carrying thousands of tonnes of cargo requires a significant distance—sometimes up to two kilometers—to come to a complete stop due to its immense forward momentum.

Speed at impact: 35 km/h (22 mph)
Braking distance initiated: 100 meters before the crossing
Required stopping distance for heavy freight trains: Up to 2,000 meters

“The driver should have stopped earlier, but the braking came too late,” explained Pichet Kunadhamraks, director general of the Rail Transport Department. While 35 km/h might seem relatively slow for a passenger car, for a multi-tonne freight train, it is an unstoppable force when given only a 100-meter runway.

The Scene of the Crash: A Devastating Collision

The accident occurred at around 3:40 p.m. on Saturday at the notoriously congested Asoke-Din Daeng railway crossing. The collision involved an air-conditioned public passenger bus that had become stuck on the tracks due to heavy, gridlocked traffic—a common sight in Bangkok’s bustling metropolis.

Eyewitness accounts and harrowing CCTV footage captured the terrifying sequence of events:

The passenger bus was stopped directly across the railway tracks amid bumper-to-bumper city traffic.
The freight train barreled toward the intersection, sounding its warning horn but failing to visibly reduce speed in time.
The massive locomotive slammed into the side of the bus, dragging it and several nearby cars and motorcycles along the tracks.
The sheer force of the impact ruptured vehicle fuel lines, triggering a massive fire accompanied by popping explosions that engulfed the bus within minutes.
Firefighters battled the intense blaze for nearly an hour before bringing it under control, subsequently pulling victims from the charred wreckage.

Emergency services confirmed that eight people, all passengers on the public bus, were tragically killed. More than 30 others were rushed to nearby hospitals with varying degrees of injuries, with several initially listed in critical condition.

Safety Protocol Failures Under Investigation

While the intoxication of the train driver remains a central focus, authorities are also heavily scrutinizing the safety mechanisms at the railway crossing itself. The intersection is a known bottleneck in Bangkok, with vehicles frequently edging onto the tracks during peak traffic hours despite warning signs.

Witnesses at the scene claimed that the automated safety barriers had failed to lower completely to block the road. However, CCTV footage also showed a railway operations officer on the ground actively waving a red flag to signal to oncoming trains that the track was not clear.

“We see the official holding the red flag, which means the track was not safe, but we also see that the train did not stop or slow down, causing the crash,” stated Bangkok police chief Siam Boonsom.

The railway crossing guard was taken into custody for questioning and has also faced initial charges of negligence. Police confirmed that his drug test returned negative. Investigators are now piecing together whether the failure lay primarily with the train driver ignoring the manual red flag warning, a malfunction of the automated barrier system, or a deadly combination of both factors.

According to reports from Thai PBS World, the crossing guard has maintained that he followed standard procedures.

The Human Toll and Community Reaction

The tragedy has deeply shaken the residents of Bangkok. In the days following the crash, locals have visited the site to lay white flowers and pay their respects to the victims. The disaster has struck a nerve with daily commuters who navigate these dangerous intersections.

“It should not have happened. I want all drivers to understand traffic laws properly,” one 20-year-old rail passenger told reporters at the scene, echoing the frustrations of many who feel that traffic laws are treated as mere suggestions.

Thailand’s roads frequently rank among the deadliest in the world, according to the World Health Organization, largely due to poor enforcement of safety standards. This incident has fueled widespread concerns that the country’s railway system suffers from similar oversight and infrastructure issues.

In response to the crash and the shocking revelation of the driver’s drug use, the State Railway of Thailand has ordered an immediate and sweeping crackdown on employee conduct. Mandatory drug screening and alcohol testing will now be strictly enforced for all train drivers, rail traffic controllers, and ground staff before they begin every shift.

Furthermore, officials revealed that the driver involved in the crash had not yet received an official operating license from the transport department. He has since been permanently suspended from duty, and authorities are investigating how he was permitted to operate the locomotive in the first place.

Deputy Transport Minister Siripong Angkasakulkiat, who quickly visited the crash site, promised a thorough, transparent investigation and full financial compensation for the victims’ families. “We must coordinate across all involved agencies to ensure that every single victim and their family receives full, swift, and fair compensation for this tragedy,” he told the press.

As the twisted metal and charred wreckage are finally cleared, and traffic slowly resumes its normal rhythm at the Asoke-Din Daeng crossing, the city is left mourning the victims of a disaster that, by all accounts, was entirely preventable. The coming weeks will likely see intense legal proceedings as those responsible are held to account, and the Thai public demands concrete assurance that they are safe when crossing the tracks.
