Abstract


In recent years, the construction of a sustainable society has been promoted from the view point of environmental protection and conservation of natural resources. Steel is the most widely used metal in the world, and numerous studies have investigated its flow and stock. However, the flow of steel for world railways has not been investigated. Although railways have been minor products for steel use, but have influence on the use of vehicles, major products for steel. So we estimated in-use stock and future demand of steel for world railways during 1980-2010. As a result, the in-use steel stock for railway vehicles and tracks in the 58 countries was estimated as 47 and 100 million ton in 2010, respectively.
