Abstract
This paper describes a new type of train control system that meets the speed
demand of 350km/h on the basis of CTCS-2. This system realizes safety train
control for 350km/h, meanwhile, it solves the key problems of train control
information content and train safety tracing interval by increasing the
information of track circuit and changing the setting of block section and so on.
Besides ETCS-1 and CTCS-3, it also implements safety train control for
350km/h. This system overcomes the shortcoming of the poor real-time
performance of spot transmission of ETCS-1 and solves some problems of
ETCS-2, such as its complicated realization and compatibility with CTCS-2 due
to the incompatibility between information transmission of track circuit and
GSM-R. This system has simple structure and good compatibility. The
implementation is low cost and easy.
With the necessity to create a new kind of train control system, this system
has been proven by analyzing the possible problems existing in the combination
between CTCS-3 and CTCS-2. The components and working principle of this
system is elaborated in this paper. The key techniques for 300~350km/h trains
are described, such as information-content, block section settings, compatibility,
reliability and safety. The performance and characteristics of this system are
compared with CTCS-2, ETCS-1, and CTCS-3.
Keywords: high-speed railway, train control system, system constitution,
working principle, compatibility.
