HYDERABAD:
The Hyderabad Metro Rail project has notched up a first in the country
by successfully conducting a test run of a train on automatic mode
between Nagole and Mettuguda.
The Automatic Train Operation (ATO) system allows the Metro train to function without any intervention from drivers. It controls the speed, movement and braking among other key functions. The role of the driver, when the train is in ATO mode, can be limited to just pressing a button to open and close the train doors at the Metro stations.
This successful test run was conducted on Tuesday night, HMRL announced on Wednesday. HMRL said Metro trains when on the ATO mode work on a communication-based train control (CBTC) system that allows control of train movement through continuous signal exchange between the trains and trackside equipment.
While the main operation control centre will be located at its Uppal depot, each of the six zones of the Metro system will be equipped with localized control systems. Each train, HMRL said, transmits its identity, location, direction and speed to the respective zone controller system which calculates the distance between two trains, braking distance and authorised train speed with automatic application of brakes in case of over-speeding. The company said that automatic monitoring of train movement and performance eliminates the possibility of human error.
The system also allows the operation of trains at a very high frequency, one for every 90 seconds, and has built-in fail safe mechanisms, HMRL said.
