Pedestrian fatalities resulting from train-person collisions.
OBJECTIVE
Train-person collisions have a significant impact in our society, due to their negative economic and psychological effects. This work aims to study fatalities resulting from train-person collisions in Portugal.


METHODS
A retrospective study was conducted based on the analysis of autopsy reports related to train-person fatalities performed in the North Branch of the National Institute of Legal Medicine and Forensic Sciences.


RESULTS
Suicide was responsible for most of the cases, and males were more often involved in train-person collisions than females. Victims, between 40 and 59 years old, were found to be involved in a high percentage (39%) of the cases, and people older than 65 accounted for a significant percentage (40%) of the accidents. No seasonality was observed in suicide cases, but a decrease in accident numbers was registered in summer. Regarding weekday and time of day, afternoon and non-rush hour were the times when most suicides were observed, whereas accidents did not showed a specific weekday or time of day, except for rush hour, during which they were more frequent. Alcohol-positive blood analysis accounting for 25% of the cases.


CONCLUSIONS
Differences from other European studies were found, which may be related to the different cultures of the countries/regions, as well as to the differences in the railway systems. More extensive studies must be performed in order to develop strategies to prevent train-person collisions.
