Creating history, Hyderabad Metro Rail has
successfully test run a train in Automatic Train Operation (ATO) mode for the
first time on Indian soil.
The metro is the first Indian project to implement
communication-based train control system. In this mode, the train operates
independently and controls its movement, speed, performance etc.
The function of the driver is only to press a button to close the doors at stations and it is a prelude to completely driverless mode which Hyderabad Metro can upgrade any time it wants.

Hyderabad Metro is the first Indian Metro which is
implementing Communication-based Train Control (CBTC) system, a very
sophisticated and latest railway signaling system.
Several sophisticated sub-systems like Automatic
Train Protection (ATP), Automatic Train Supervision (ATS), Vehicle on Board
Controller, Zone Controller, Data Communication System, Solid State
Interlocking (SSI), etc ensure absolutely fail-safe protection mechanism
against train collisions, speed regulation, programmed stopping, door control
and other functions. Automatic monitoring of train movement and performance
remove any possibility of human error and prevent train collisions due to
driver passing train beyond danger signal, which can happen in normal railway
working.
The hi-tech CBTC system adopted by Hyderabad Metro
facilitates running of trains with one and a half minute (90 sec) frequency
with very high reliability. It has built in redundancies to take care of
failure of any component.
Most of the important Metros in the world have
switched over to CBTC technology and after Hyderabad Metro, the next phase of
Delhi Metro has also opted for this technology. Hyderabad Metro is using the
latest version of CBTC technology.
