The railway system can generally be divided into three parts.One part is the infrastructure, which includes the lines, bridges, and tunnels. It
is called the fixed part of railway Fsystem. The second part is the rolling stock,
which is called as the movement part of railway system. The third part is the
signaling system, which is called the brain and the nerve system of railway
system.
As shown in Fig. 1, trains run on the lines controlled by the signaling system
in any railway systems. Therefore, the signaling system ensures trains to operate
safely and efficiently. The roles and functions of the signaling system in railway
systems are clearly stated in Fig. 1. It is obvious the signaling system is the brain
and the nerve system of railway system. Without signaling system, railway
systems cannot operate efficiently and safely. It also can be seen that the
signaling system has close relationship with rolling stocks and infrastructures.
The configuration of the signaling system is given in Fig. 2. Usually, there are
four parts included in the signaling system: (1) On-board control system, (2)
Station control system and wayside system, (3) Central control system, (4)
Communication network including mobile telecommunication.
The core systems of the signaling system are consisted by the above four
parts in Fig. 2. The interlocking system and RBC (Radio Block Control) belong
to the station control systems. The on-board control system, control center and
the communication system are also one of the core systems for signaling system.
In more details, the vital computer for interlocking system, on-board system and
RBC system, and the basic software for the four parts are also belong to the core
part of the signaling system. In the paper, the core systems are the foundation of
the signaling system, and are called as the basic models of the signaling system.
Up to now, the functions of the signaling system in railway system, and the
relationship between the core systems and the signaling system are explained.
When ETCS or CTCS is analyzed, the four parts, or the core systems can be seen
easily. In the ETCS, there are Euro-cab, Euro-radio (GSM-R) and Eurointerlocking,
etc. In the CTCS, there are Chinese on-board system (Universal cab
signaling), GSM-R and Chinese interlocking systems (four kinds of interlocking
systems), etc. as in Ning et al.
