Analysis of Influencing Factors of Energy Saving and Emission Reduction for Railway Transportation of China

The current status of energy saving and environment protection in railway sector is analyzed in this paper. The passenger transport-related energy consumption has degraded dramatically, and the freight-related energy consumption on the decline in general, but the energy consumption per unit grows slightly in last two years, due to the shrinking of rail freight volume. Then, the key effective factors of energy saving and environment protection are presented from the aspects of key facilities and equipment and operation management. Finally, based on the development status of China railway, some new technologies and measures of energy saving and environment protection in four perspectives are proposed, such as life cycle management of railway system, lightweight cabin design and manufacture, comprehensive energy consumption control and energy recycle, and high-efficiency operation.
