With the description of Chinese Train Control System Level 3 (CTCS-3) system structure and work principle, the author proposes an Intelligent Control Strategy (ICS) to improve CTCS-3 safety. Through the integration with two different train-wayside communication methods that based on GSM for Railways (GSM-R) and track-circuit, CTCS-3 realizes the cross line and degraded operation in high-speed railway. CTCS-3 with independent control unit of C3 and C2 that have been used to control 300~350km/h train and C2 200~250km/h train respectively still carries the whole function and equipment of CTCS-2. Through the exchange of information between C2 and C3 control unit, the ICS produces more reliable and precise core train control data after the intelligent data fusion of movement authority (MA), track data and temporary speed restriction (TSR), etc. After intelligence fusion, the probability of common cause errors has reduced and the scope of security directive role has been limited. The integrated date allows us to calculate permitted speed and generate supervising profile that ensures the safety of automatic train protection (ATP).
