The paper concentrates on a cost control and management problem of high-speed railway signal systems when the project managers require to organize, implement, and assess the project cost. When it comes to the existing issues of implementing railway signal project, the management process’s actual performances are presented, including the weak awareness of refined management and the lack of the financial management information system. Aiming to reduce project cost and safe operation of the signal systems, the refined cost control and management methods and concrete measures are presented during the concrete stage involving project bidding, preparatory, implementation, and completion.
