Abstract Research purposes:The railway profile design is a complexly systematical work and it's inefficient and easy to make mistakes if the manual design is made. To study and master the methods for autodesign and optimization of railway profile can improve the profile design efficiency and quality，provide the quick reference and guidance to optimizing and adjusting the railway profile scheme and lay a solid foundation for the linkage design of railway plane，vertical section and transect.

Research conclusions:The applicable examples show that the autodesign of railway profile by making the grade simulation and many consraints processings can quickly find the initially valuable profile scheme and it can provide quick reference to the railway profile design and optimization. On the basis of the achievement of the autodesign，the differential evolution Algorithm一based optimization of the railway profile can improve optimization speed and effect. The efficiency and quality of railway profile design can be much improved by adopting the autodesign，automatic optimization and automatically normal checking.

Key words： railway profile autodesign optimization constraints processing differential evolution
