Abstract: In response to the growing demand for railway informatization construction, as well as the needs to ensure the information security of railway information systems and enhance the research and development (R&D) management capabilities of railway application systems, this paper proposed an optimization scheme for the existing railway R&D and testing platform, and elaborated on the overall architecture, technical architecture, and core functions of the scheme, as well as the key technologies of the optimized platform. This optimization scheme can standardize the development and testing management processes of R&D projects, improve the management and control capability of development and testing workflows, ensure the security and traceability of system software source code and deliverables, and thus ensure the security, reliability, and smooth deployment of information systems.
