Expert Report Says Ignored Warning Signals Worsened Gotthard Train Derailment

A new expert investigation into the 2023 Gotthard Base Tunnel derailment has revealed that warning signals were reportedly ignored before the major railway accident occurred.

According to a report commissioned by the Ticino public prosecutor’s office, Swiss Federal Railways (SBB) may have been able to prevent or reduce the severity of the derailment inside the Gotthard Base Tunnel.

The accident happened in August 2023 after a wheel on the eleventh freight wagon broke while the train was travelling through the tunnel. The failure caused extensive infrastructure damage, resulting in repair costs estimated at around CHF150 million and the closure of one tunnel tube for more than a year.

The newly released findings, obtained by Swiss broadcaster SRF, state that a series of warning alerts appeared in SBB’s operational systems after the wheel defect occurred. However, operators allegedly failed to react to the warning messages in time.

Investigators believe earlier intervention, including emergency measures to stop the train, could potentially have limited the scale of the destruction inside one of Europe’s most important rail corridors.

The report has sparked renewed debate over railway safety systems, operational procedures, and monitoring technology within Switzerland’s transport network.

Industry representatives and transport experts are now calling for a detailed review of emergency response protocols and automated warning systems to prevent similar incidents in the future.

The Gotthard Base Tunnel is a key part of European freight and passenger transport infrastructure, linking northern and southern Europe through the Swiss Alps. The prolonged closure following the derailment caused significant disruption to international rail traffic and logistics operations.

Authorities are expected to continue examining accountability and operational responsibilities as part of the ongoing legal investigation.

New Report Claims Swiss Rail Operator Could Have Prevented Gotthard Tunnel Accident

A new expert report into the 2023 Gotthard Base Tunnel accident has concluded that Swiss Federal Railways (SBB) could potentially have prevented the severe incident that caused major damage and a prolonged tunnel closure.

The accident occurred in August 2023 when a broken wheel on a freight wagon led to serious damage inside the Gotthard Base Tunnel, resulting in losses estimated at around CHF 150 million and a closure lasting over a year.

According to the report commissioned by the Ticino public prosecutor’s office, multiple warning signals appeared on SBB’s operational monitoring systems after the wheel failure. However, the report claims that these alerts were not acted upon in time, allowing the train to continue through the tunnel.

The findings suggest that earlier intervention, including an emergency stop, could have reduced the severity of the damage or possibly prevented it altogether.

Criticism has since emerged from industry representatives. Josef Dittli, who also leads an association of freight wagon operators, stated that the system failed to respond appropriately despite clear warning signals.

Railway union representative Philipp Hadorn also questioned the lack of emergency braking, arguing that the response did not align with standard safety expectations in such situations.

The report highlights broader concerns about safety monitoring systems in complex rail infrastructure such as the Gotthard Base Tunnel, one of the most important transport corridors in Europe.

The findings are expected to prompt further discussions on operational safety procedures, digital monitoring systems, and emergency response protocols within Switzerland’s rail network.
