## Abstract

Train surfing, the practice of riding on the exterior of moving trains or subways, is an increasingly prevalent phenomenon, particularly among urban youth, and is partly fueled by social media exposure. While it provides an adrenaline rush, it presents significant risks, including electrocution, falls, and collisions with objects. This study aims to investigate the forensic aspects of fatalities associated with train surfing incidents, focusing on cases examined by the Institute of Forensic Medicine at Charité University in Berlin between 2010 and 2024. A total of 15 fatalities resulting from train surfing were analyzed, all involving male victims aged 15–24, with the majority of incidents occurring during the summer months. The primary cause of death was traumatic injury (11 cases), resulting from falls or impacts with obstacles, while electrocution (particularly from high-voltage contact or electric arcs) was responsible for the remaining 4 fatalities. In many cases, victims sustained multiple injuries, including isolated cranial trauma and polytrauma involving the head. Forensic findings, such as electrical burn marks and blunt force injuries, were crucial in differentiating between electrocution and trauma. Toxicological analyses revealed the presence of substances like alcohol, THC, and cocaine in several cases, underscoring the role of substance use in these incidents and in the reconstruction of events. This research emphasizes the need for comprehensive forensic protocols to address such cases, as train surfing remains a significant public safety concern.
