Introduction Metro Rail system implemented in underground as well as flyover system. The two components used for the automation of the Metro Rail systems are 1) Programmable Logic Controllers (PLC). & 2) Supervisory Control and Data Acquisition (SCADA) .
Programmable Logic Controllers (PLC) A PLC is a user-friendly, microprocessor based specialized computer that carries out control functions of many types and level of complexity. Its purpose is to monitor crucial process parameters and adjust process operations accordingly. Hence it is used for the automation of metro rail systems.

SCADA SCADA stands for Supervisory Control and Data Acquisition. SCADA is a control system architecture that uses computers, networked data communications and graphical user interfaces for high-level process supervisory management, but uses other peripheral devices such as Programmable Logic Controllers to interface to the process plant or machinery.

Advantages Train locations can be identified and controlled after interruption of power supply Collision of trains can be avoided. Accidents are avoided.
Disadvantages IR Sensors senses only particular direction. Wiring Connectivity is more from one sensor to other sensor. This system gives information to station not the engine operator.
Conclusion By employing PLC automation can be achieved. SCADA is used to track the location of Train to avoid the accidents. Speed can be reduced by the sensors and Inter Passage Door opening is provided for safety of passengers.
Future scope By implementing PLC and SCADA in metro rail automation the train accidents can be prevented and many lives would be saved.
