\r\nThe line, which forms a loop north of Sikandepur serving businesses and facilities in Gurgaon Cyber City, is India's first public-private partnership (PPP) metro project. It was built at a cost of Rs 11bn ($US 178.6m) by a consortium of ITNL ENSO Rail Systems, IL&FS Transportation Networks and property developer DLF. Ticketing is integrated with Delhi's existing metro network and services are being operated by Rapid Metro Gurgaon. The line is expected to carry 30,000 passengers per day, operating between 06:05 and 00.20, with 2-minute headways at peak times.\r\nSiemens was awarded a turnkey contract for the new metro line in April 2010. It subsequently supplied its Sicas ECC type interlocking, the LZB 700M automatic train control system which includes automatic train protection and automatic train operation, and its Vicos OC 501 automatic train supervision (ATS) system. It also supplied the 750V dc third rail electrification system. Siemens designed and supplied traction equipment for the seven three-car aluminium-body trains, which operate at a maximum speed of 80km\/h, and were manufactured by CSR Zhuzhou.\r\nSiemens also secured an additional turnkey contract to extend the line by 7km and six new stations to the south of Sikandepur. This work will be completed in 2015.
