Derailment is one of the most significant railway accidents, leading to considerable human and financial losses. This thesis eva‎luates the technical and economic feasibility of using emergency train stopping equipment following a derailment. In this research, various emergency stopping devices—such as EDT101, 3D&FAT, TD2S, and Sicode-EP—are examined in terms of performance, efficiency, and cost-effectiveness. The study includes an analysis of accident statistics and derailment-related costs in Iran over the past five years, as well as a comparison of the productivity of Iran's freight wagons with those of other countries. Additionally, the impact of delayed stopping on increasing derailment costs is investigated, with case studies focusing on major railway accidents such as Sorkhabad-Veresk and Chahtar-Tezerj. Finally, an economic analysis of installing the aforementioned equipment forms a crucial part of this thesis. The results indicate that the use of these devices is not only technically effective but also economically viable, significantly contributing to cost reduction and improved safety in Iran's railway network. Implementing such equipment, particularly for wagons carrying hazardous materials and passenger coaches, can enhance railway transportation safety and prevent severe damages.
