Abstract: China's high-speed railway construction is changing from focusing on "project quantity and scale expansion" to focusing on "quality, safety and efficiency". In order to meet the higher requirements of the new construction mode on the construction technology, based on the construction operation standards of Beijing–Shenyang high speed passenger dedicated line, focusing on the railway passenger service information engineering, aiming at delivering safe and high-quality projects, and referring to the installation experience of high-speed railway passenger transport service system engineering equipment, this article expounded the process quality standards.On this basis, the article established the process quality evaluation system to comprehensively evaluate the implementation quality of the project, so as to provide reference for building excellent passenger service information engineering
