New Delhi: Delhi Metro Rail Corporation Ltd (DMRC) awarded Japan-based Nippon Signal Co. Ltd. with a contract to supply communications-based train control (CBTC) system for Line 8 – the capital city’s first driverless metro line, which is currently under construction. Nippon has chosen Frauscher Sensor Technology India Pvt Ltd as a partner for supply of axle counters for this project.
Axle Counter as fall back arrangement in CBTC system
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. In order to facilitate this requirement, Nippon has chosen RDSO-approved Frauscher-make Axle Counter System ACS2000. The contract awarded to the company involves approximately 300 track sections and about 312 counting heads.
Ideal choice for DMRC metro project
“We are glad to be a part of the upcoming metro project of the country’s capital. Track vacancy detection forms an essential element for confirming track availability and conducting safe operations.
“Tested and proven Frauscher ACS2000 used along with Wheel Sensor RSR180 can be customised to suit unique requirements. Also, in case of 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.
First driverless train in Delhi
The Line 8 ambitious project of DMRC is the first driverless train operation system in Delhi. The project will be spread across 36.4km line, which will follow the outer ring road south of the city from Janakpuri West to Hauz, Khas, Kalindj Kunj, and botanical garden in Noida. 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 rapis increase of vehicles.
The first phase of Line 8 will open in June 2015 and services will be operated by six-car trains with peak headways of 2 minute 15 seconds, with a commercial speed of around 35km/h, and the hourly capacity being higher than existing Metro lines of DMRC.
