Normal Mode： Normal service startup, revenue operation and service shutdown with no
major disruption.
Incident Mode： Occurrence of incident that does not result in major service delay or injuries.
For example, train-stalled in tunnel.
Emergency Mode： Occurrence of an emergency situation that causes major service delay or
serious injuries. For example, ‘train-on-fire’ in tunnel.

This is illustrated in the following diagram:

4、System Configuration

4.1 System Overview

The OASYS C3 solution is designed to operate from the Operation Control Centre
（OCC）, the Depot Control Centre（DCC）and the Passenger Stations（STN）; a typical
requirement for railway system. In addition, other supporting subsystems（Testing and Training
Systems etc.,）can be set up.

At the OCC, the C3 solution provides the control room operators with real-time
command, control and operation support functions over the entire railway line through the
multi-functional Operator Workstations（OWS）and the Overview Display System（ODS）. The
Graphical User Interface（GUI）on the OWS and ODS provides the operator with animated
symbols, icons, schematics, textual and adjustable annunciation for efficient and effective
operation. All supporting communication functions（data, voice and video）are available to the
