Abstract
This paper presents a new Chinese Train Control System (CTCS), the CTCS-2I, for trains traveling up to . Building on the capabilities of CTCS-2, the CTCS-2I system provides safety control for trains traveling at by increasing track-circuit information capacity, changing block section parameters, and adjusting other crucial settings. It solves some key issues of the CTCS-2I system operating on trains, including train-operation control information content and safe train-tracking intervals. The CTCS-2I offers a train-control system in addition to the European train-control system, ETCS-1; and CTCS-3, which both provide safety control for trains traveling at . Furthermore, the CTCS-2I overcomes the shortcomings of real time in the point-type ETCS-1 and averts complications in CTCS-3, including poor compatibility between CTCS-3 and CTCS-2, as well as the structural overcomplexity of CTCS-3 caused by incompatibility transmission in the track circuit and Global System for Mobile Communications–Railway (GSM-R). By contrast, the CTCS-2I system is characterized by its simple structure, good compatibility, low cost, and easy implementation. The necessity of creating a new kind of train-control system, CTCS-2I, has been proved through analysis of the potential problems found in both the CTCS-3 and CTCS-2. The components and working principles of CTCS-2I are detailed in this paper. The key control techniques for trains, such as information content, block section settings, compatibility, reliability, and safety, are also described. The performance and characteristics of the CTCS-2I are further compared with CTCS-2, ETCS-1, and CTCS-3.
