The 7th International Symposium on Innovation & Sustainability of Modern Railway (ISMR 2020) was scheduled on Oct. 23rd to 25th. We are proud to have Prof. Xiaoyan LEI, the principle of East China Jiaotong University, and Prof. Erol GULER from George Mason University to be the keynote speakers.

Special thanks to China Academy of Railway Sciences, Lanzhou Jiaotong University, and Southwest Jiaotong University, for their active participation to the conference. They are among the top research institutes in the field of railway sciences in China and presentations from them can represent the mainstream of recent railway studies.

In this special year under the influence of global pandemic, we have received 89 submissions and the review work has lasted for four months since May. With the help of TPC members and reviewers, 38 articles including two works from keynote speakers were included in the proceedings, with 12 articles talking about Railway & Mechanics, 20 articles focusing on Railway & Computer Sciences and 6 articles related to Railway & Management.

This collection aims to provide experiences and bring new ideas to railway practitioners. Development of railway science is of great significance to both economy and society. We can see that transdisciplinary study between railway and other subject has become a trend in future study.
