The Railway Technical Research Institute (RTRI) has been developing "railway simulators" as a common platform for developing advanced railway simulation technology and has successively implemented research projects every five years since 2010. In the last five years (2015-2019), RTRI has developed a "virtual railway test line" and a "coupling environment for individual simulators". The virtual railway test line, which reproduces the dynamic behavior of the railway system during train operation under various conditions, is used to perform virtual running tests. The railway simulator coupling environment, which uses coupled calculations by linking multiple simulators, is used to carry out comprehensive analyses. This report outlines these achievements and introduces future research prospects.
