The total exergy and exergy efficiencies have been calculated based on the energy utilization of Chinas railway transport from 2006 to 2010. The preliminary results indicate that: (1) the major fuels for China railway transport are diesel, coal and electricity; (2) The total exergy consumption is calculated as 491.59 PJ in 2006 and 480.19 PJ in 2010, which is approximately in accordance with Chinas economic growth rate. (3) With railway electrification and green technology being emerged in the transport system, the energy structure is considered upgrading gradually, e.g. more environment-friendly energy is used to be the alternative fuels. (4) The weighted mean of exergy efficiencies range from 26.41% to 26.62%, which are less than the conventional efficiency 28%, due to the irreversibility of exergy loss. In addition, both time and structural variation of the total exergy consumption and efficiency provides an insight to China's socio-economy, but also helps improve the national energy policies.
