Research purposes： The researches are done on the successful application experience of ETCS - 1, including the application of the existing automatic block technology in China to make up the insufficiency of point - continued type train control system and the application of point and continuous information as a whole, for the purposes of improving and optimizing the design and construction of CTCS -2 point- continued type train control system.Research methods：The analyses are made in details for the difference between traditional train control mode and point -continued train control mode. Aiming at the limitation of track circuits to be train control system of high - speed railway, the point- continued design is presented.Research results： CTCS -2 point -continued train control system based on track circuits and Balise overcomes the shortages of the existing train control system, which has a great significance to improvement for the development of passenger dedicated line （PDL）. Research conclusions：CTCS -2 point -continued train control system can increase the train control messages between train and ground communication, realize the speed- distance train control mode and improve the traffic efficiency sufficiently.
