Abstract: The correctness of the data, provided by the Train Control Engineering Data sheet, the foundation of the configuration data of CTCS-2 and CTCS-3, affected directly the security of Train Control System. Therefore, the auditing of the data played a great role of importance. In recent years, with the development of China high-speed railway, the auditing work became more arduous and onerous. The existing train control data auditing techniques was discussed in this paper, so as to design and develop a tool of automatic train control data auditing.
