The ATS also includes data loggers to record all operational data. The data can then be
displayed and used for reports as necessary. This includes any unscheduled stoppages or delays,
including time of occurrence and time of resumption of operation complete with the identification
number for the train.
In the event that the ATS fails, for example, through a catastrophic failure, the system
continues to operate with trains running according to their current schedule and headway regulation,
which is controlled by the RATO.
The ATS system monitors and manages the overall system operation. The ATS is not essential
to continuing automatic system operations by the ATO and ATP once operations have been started.

2.3.2 Automatic Train Control（ATC）

The ATC system is divided into two sub-components, wayside and onboard.
The Wayside ATC is divided into a number of regions or geographic areas for each metro line
and the number of regions used for a specific line depends on the length of that line and the number
of trains on the line. Often the term “Region ATC” is used as a general term. “Region ATC” refers
to a complete set of Region Control equipment which includes, but is not necessarily limited to,
Region ATP, Region ATO and TWC Equipment. Each Region ATC can control several interlockings
（collection of switches or points）；therefore the ATC equipment may be centralized at one station.

The Region ATP, Region ATO, and remote Region ATP computer systems are responsible for
the safe and optimal performance of the CITYFLO 650 Train Control system. Information flows
between these sub-systems through the Wayside Network backbone and through to the Central
Control Network.
