The upcoming Line 8 of Delhi Metro’s Phase-III with advance metro signaling system will be operated without drivers and its operations will begin June. Delhi Metro Rail Corporation (DMRC) awarded Japan based Nippon Signal Co Ltd, a contract worth around 3.7 million JPY for the signaling system.
The advanced signaling system Communication Based Train Control (CBTC) will help trains on Line 8 Janakpuri to Kalindi Kunj — up to Botanical Garden in Noida Sector 32 to run without a driver’s help.
“The Line 8 will be the first driver-less train operation system in Delhi and first phase of it will be going in for operations from June month onwards. The project will be spread across 36.4km line,” a statement from Frauscher Sensor Technology India Private Limited.
The frequency of driver-less trains would increase and the gaps between two trains would come down due to CBTC technology.
“The services will be operated by six-car trains with peak headways of 2min 15sec with a commercial speed of around 35km/h and the hourly capacity being higher than existing Metro lines of DMRC,” statement added.
Nippon Signal Co. Ltd is the first Japanese company to win a contract in India metro signaling system with a contract to supply CBTC system for Line 8 - the capital city's first driverless metro line. Nippon has chosen Frauscher Sensor Technology India Pvt. Ltd. as a partner for supply of Axle Counters for this project.
In a CBTC system, as a fall back arrangement; Axle Counters are used as track vacancy detection system to locate the train in case of failure of primary radio communication. The contract awarded to the company involves approximately 300track sections.
“Track vacancy detection forms are an essential element for confirming track availability and conducting safe operations. In CBTC technology the tested and proven Frauscher ACS2000 is used along with wheel sensor RSR180 and it can be customized to suit unique requirements. For mass transit applications, it is preferred not to drill holes on the track to fix axle counter wheel sensors. All Frauscher wheel sensors can be mounted on track using the patented rail claw without drilling. The absence of any electronics on the trackside location boxes, the quick installation process, and the product’s ability to function under extreme environmental influences, makes ACS2000 an ideal choice for this project,” said Alok Sinha, Managing Director, Frauscher Sensor Technology India Private Limited.
The Line 8 will have 26 stations, 12 of them underground, and 19km of the route will be elevated or at grade with the remaining 17.3km in tunnels. The new line is a much anticipated solution for traffic congestion on roads due to rapid increase of vehicles . The Metro line will follow the outer ring road south of the national capital from Janakpuri West to Hauz Khas, Kalindj Kunj and Botanical Garden in Noida. The line will also serve as an alternate to Dwarka — Noida section for people who travel between west Delhi and Noida.
The Phase III of Delhi Metro will cover 70 percent of the capital city's population and it include neighboring National Capital Region (NCR) like Faridabad and Noida.
