HITACHI RAIL WINS BID TO DELIVER AUTONOMOUS DIGITAL SIGNALLING FOR CHENNAI METRO

Hitachi Rail recently signed the contract to deliver digital signalling for Phase 2 of the Chennai Metro Rail Project.

The CBTC system automatically controls the train’s traction and braking to continuously calculate optimum speed. The technology will allow trains to run at up to 90-second intervals, providing significant capacity as well as reliability on Phase 2 services.

By installing Automatic Train Operation (ATO) technology, Phase 2 trains will be able to depart, run at optimum speeds, and brake automatically, without the need for a driver. The technology will boost safety and drive significant maintenance savings. The system will also use ATO technology at the depot, for the operation of doors, and for passenger information and display systems.

The digital signalling system will be installed on the fourth longest metro system in India, serving the city of Chennai, Tamil Nadu. Phase 2 of the Chennai Metro Project will include 119km of line, with a significant proportion (42km) underground.

The contract will be funded by the Japan International Cooperation Agency (JICA). It covers the design, manufacture, supply, installation, testing and commissioning of the signalling, train control and video management system.
