The rail transport of goods is a safe and convenient way for transport in cities and intercity ways, which aim is to increase the amount of goods transportation. Rail transportation is more secure than other vehicles and fewer rail accidents occur; however, if it leads to an accident, it will cost more and further damage the credibility. The rail transport can be used for international and domestic transportation and is usually used to transport wood, iron, industrial loads, raw materials, bulk dry goods and other commodities in high volumes. When a commodity has a high weight, number, and dimensions and a proper road transportation vehicle is not available, the trains can be used. The railway transportation in Iran and other countries is important from two aspects: One is that the rail route is considered to be a cleaner way of transportation and is cleaner than other modes of transport. The other aspect is its higher safety than other methods.
