Abstract: The scheme design of high-speed railway train control system for liaison line shall be coordinated with civil work. This paper sets a project as an example, degrading the train control system of liaison line to the CTCS-2 scheme. The technical analysis is performed with regard to operational scenarios, combining the factors such as big number turnouts, temporary speed restriction and code sequences. The corresponding operational management measures are put forward to provide a reference for the similar projects.

Key words: short-distance liaison line, degrading, CTCS-2 train control system
