Abstract：Wenchuan Earthquake and its characteristics as well as main types and features of railway engineering damage are described in brief. Such issues as lifeline project，secondary geological hazards induced by earthquake，near-field effects of earthquake and engineering design in near-field region，revision of seismic design standards for railway engineering and research on key technology for seismic design of railway engineering are discussed. The following suggestions for further research work on railway engineering seismic design are put forward. Enough attention to lifeline project should be paid in railway network planning and engineering construction. For the railway engineering in high seismic intensity mountain area，significant attention must be devoted to integrated location of railway and overall design based on prevention and mitigation of collapse and landslide induced by earthquake，and the sections where large-scale collapse and landslide incurred by potential earthquake shall be evaded，meanwhile，the high slope cutting of subgrade shall be avoided instead of selection of engineering form in favor of earthquake disaster prevention and reduction. For the engineering located in high seismic intensity region or on seismic fault zone，the relevant engineering technical standards on how to reduce earthquake hazard and repair earthquake damage rapidly shall be studied. Revision of code for seismic design of railway engineering shall be started as soon as possible，in which the requirements of design standard and method for engineering in earthquake near-field，especially earthquake fault zone，as well as the principles of integrated location of railway and overall design based on precaution and reduction of secondary seismic geologic hazard shall be added. The research on key technology for railway engineering seismic design in high seismic intensity mountain area，such as the integrated location of railway in high seismic intensity mountain area based on prevention and reduction of secondary geologic hazard and train operation control based on pre-earthquake forecast，etc.，is also recommended.
