Evaluation of trauma and prediction of outcome in 255 train accident victims in Delhi was studied out of which 40 cases survived and taken up for this study. Trauma and Injury Severity Score (TRISS) was calculated and its correlation with period of survival was determined. Males and females were 86.7% and 13.3% respectively. Mean age was 37.5 years. Most common age group involved was 21–30 followed by 31-40 years. The region of the body most commonly involved in survivors was the lower limbs followed by upper limbs, head and chest while in the victims who died was head followed by chest and abdominal injury. Thirty percent of the survivors belonged to TRISS group 50-80 followed by 70% survivors to TRISS >80 group. There was a positive correlation between TRISS and probability of survival.
