\r\nThe initial 5.1km section of the metro is expected to open in September will run north from an interchange with the Delhi Metro Yellow Line station at Sikanderpur, looping round to serve Gateway Towers and Moulsari Avenue. The second phase runs south for 7km from Sikanderpur following the route of Golf Course Road to Sector 55-56 with six new stations.\r\nSiemens will supply its Sicas ECC type electronic interlocking, LZB 700M automatic train control with ATP\/ATO, and its Vicos OC 501 ATS system. The minimum headway will be 120 seconds, giving the line capacity to carry 30,000 passengers per direction per hour.\r\nThird rail 750V dc electrification will be installed and power will be supplied to the extension from the 66kV grid. A medium-voltage ring will supply 11kV ac power to four substations, six metro stations, and the depot.\r\nSiemens will supply seven three-car trains for the extension, which will supplement the existing fleet of five trains. Each train will accommodate up to 760 passengers.\r\nThe second phase is due to open by the end of 2015. In the longer term, a further extension towards Udyog Vihar in the north is proposed which will take the total length of the network to almost 20km.
