The main function of the on board communication system

of the MRT Project is to provide the needed communication tool for the control center, the train driver, or the passengers. The

system functions and operating features are described below:

A. Public Address system: the driver can personally broadcast

to passengers on the train or automatically (for example:

station name broadcast, pre-recorded message broadcast).

B. Intercom System: In case of emergency, passengers can

make calls via the emergency intercom to train drivers.
