Safety Analysis On Railway Exceptional Dimension Freight Transportation

Exceptional dimension freight is the generic term of overrun goods, long goods, concentrated weight goods, and it has long, big, heavy features, most of them are large equipments needed for the development of national economy. Exceptional dimension freight has complex shape, huge column, expensive price, and high delivery requirement, so when transporting exceptional dimension freight by railway, we must not only select the vehicles rigorously, and must comply with its load-reinforcement conditions.The thesis is focused on the exceptional dimension freight’s transport safety issues, including the following sections.(1) Introduce the base types of exceptional dimension freight, and analyze the overrun goods, long goods, concentrated weight goods. Discuss the load-unload requirements during railway transportational process and research on the transportation organization and reinforcement issues.(2) Focused on railway exceptional dimension freight transportation, this thesis analyze of the factors affecting the safe transportation from the load-reinforcement, track parameters and management level three scheme.(3) Fault Tree Analysis focuses on exceptional dimension freight transportation. Find out the key safety factors of the system mainly from three element (long goods, overrun goods and concentrated weight goods).(4) Construct safety evaluation factor system of exceptional dimension freight transportation. Take a research on the safety evaluation method of the system.(5) Finally, according to the results of FTA and safety evaluation, put forward countermeasures and suggestions to the exceptional dimension freight transportation.
