Indian Railways, the largest railway network operator in Asia, has tied up with Nokia Siemens Networks for equipping the Kolkata metro line with Global System for Mobile Communications Railway (GSM-R) infrastructure.

This will further improve the safety and reliability of the Kolkata metro line while lowering operational costs for Indian Railways. Nokia Siemens Networks already supports Indian Railways’ extensive rail network spanning 3,500 km across four zones. As a result of this expansive GSM-R deployment, Nokia Siemens Networks has become India’s top GSM-R solutions provider.

As part of its GSM-R deployments, Nokia Siemens Networks is providing its compact, energy efficient Flexi Base Stations and Flexi Base Station Controllers that offer vastly improved capacity.

The company is supplying all operational components including switching centers, Intelligent Network (IN) platforms, service and management platforms, controller data transmission elements and mobile handsets for drivers. In addition, Nokia Siemens Networks is providing its In Building Solution to enhance indoor coverage for the Kolkata metro project. The scope covers care services that include spare part management, software maintenance, third party software support and training.
