Nokia network solution for Indian rail system

Nokia is working with Alstom to deliver a private wireless network for India’s National Capital Regional Transport Corporation’s Delhi to Meerut Regional Rapid Transit System (RRTS). It will support European Train Control System (ETCS) Level 2 signalling to maintain safety for commuters on the high-speed rail route, currently under construction.

The Delhi to Meerut RRTS is the first in a phased development of a high-speed rail network connecting Delhi and the surrounding districts. Expected to be fully operational in 2025, the low-emission RRTS will transport more people at average speeds of 100 km/h to reduce travel time and road congestion.

The redundant private network, based on the Nokia Modular Private Wireless solution include: AirScale radios, Air Frame-based evolved packet core capabilities, the 7250 IXR IP/MPLS backhaul routers, Group Communication platform for mission-critical push-to-talk/video and Network Services Platform management. It will span the 82-kilometre rail route, which incorporates 25 stations.

The private network is being deployed to support signalling as well as automated operation, which enables trains to use radio signals to continuously receive their movement authorities and to report their exact direction and position to ensure the safety of all on board.
