Although less frequent than automobile accidents, train accidents have a major impact on victims' lives.
Records of patients older than 16 years of age admitted to the Adult Emergency Department of Hacettepe University Medical Center due to train accidents were retrospectively evaluated.
44 patients (30 males, 14 females) with a mean age of 31.8±11.4 years were included in the study. The majority of the accidents occurred during commuting hours. 37 patients were discharged, 22 of them from the emergency department. The mortality rate was 7/44 (16%). Overall mean Revised Trauma Score (RTS) was 10.5 (3 in deaths and 11.9 in survivors). In 5 patients, the cause of death was pelvic trauma leading to major vascular injury and lower limb amputation. In 1 patient, thorax and abdomen trauma and in 1 patient head injury were the causes of mortality. Primary risk factors for mortality were alcohol intoxication (100%), cardiopulmonary resuscitation on admittance (100%), recurrent suicide attempt (75%), presence of psychiatric illness (60%), and low RTS.
In this study, most train accidents causing minor injuries were due to falling from the train prior to acceleration. Nevertheless, train accidents led to a mortality rate of 16% and morbidity rate of 37%. These findings draw attention to the importance of developing preventive strategies.

    ABSTRACT: Foreign body recognition of locomotive roof is an important security link. In this paper, a foreign body recognition method is presented based on shape feature matching. Roof images of the inherent devices (without foreign bodies) and those of the running train are processed respectively with the cubic B-spline wavelet edge detection to get multi-scale edge images and segment objects. And thus the invariant moments of each closed area in the edge images are extracted. Then, after calculating the similarity measure by Euclidean distance, we can judge whether the objects are foreign bodies. Test results show that this method can effectively recognize a foreign body in the size of 33 mm x 33 mm.

    ABSTRACT: This review covers a central aspect in railway safety which is the prevention of suicides and trespassing accidents. The paper attempts to answer the following research question: 'What measures are available to reduce railway suicide and trespass, and what is the evidence for their effectiveness?' The review is based on 139 relevant publications, ranging from 1978 to 2014. The analysis aimed to identify the past and current trend in the prevention practice by looking both quantitatively and qualitatively at the recommended measures. According to the results, there has been a constant focus on suicide prevention, and only relatively recent interest in trespass countermeasures. The content analysis revealed 19 main preventative categories which include more than 100 specific measures. We identified 16 common categories against railway suicide and trespass, and 3 categories of specific measures to prevent suicide. There are only 22 studies which provide empirical support for the effectiveness of measures. Actual combinations of measures are barely evaluated, but several challenges emerge from the literature. The discussion focuses on the need for a unified approach to suicide and trespass prevention, and on the importance to consider the effect mechanism of the measures in order to design better interventions.
