The regulation involved with railway vehicles is defined by law to protect customer and fundamental safety. The persisting period of domestic railway vehicles in general are 25~30years. Expired railway vehicles are disused in various way. The railway vehicles are consists of recyclable various materials, but there is no standardization or calculating method related with railway vehicles to make disuse scenario. In this study, performed to get a recycling ratio about major materials of domestic subway railway vehicles using ISO 22628 which is Road vehicles-Recyclability and recoverrability method. This research provide foundation for further researches, standardization of EoL stage and recycling railway vehicle.

World Business Council for Sustainable Development(WBCSD) is effort to achieve sustainable development in economic growth, environmental preservation and social development. Being this way, it is essential for developing evaluation tool which quantify to fulfill sustainable development. Eco-efficiency is one of the quantitative tools to evaluate environmental impact and economic aspect. Eco-efficiency, in general term, means creating more value of product or services with less impact to environment. It indicates as environmental impact in denominator and value of product or services in numerator. Eco-efficiency shows how much economic value reveals to unit environmental impact caused by product or service as an indicator. This study aims at developing eco-efficiency indicator of railway industry considering use stage among the entire life cycle stage of KTX and Saemaul train and also, figure out eco-efficiency value through indicator. Therethrough, it is enables to evaluate created value per environmental aspects. Since rail vehicles demands a lot of energy to transport people during use stage, the environmental impact is more significant than other lkfe cycle stages. Therefore, it quantified environmental indicator as CO2 emission and economic indicator as transportation record per a year with an annual income. This study contributes to be used as a tool for quantifying indicator of comparison evaluation in respect of rail vehicle in use stage.
