Following this, DMRC took over operations of Airport Express line from 1 July 2013 with an operations and maintenance team of 100 officials to handle the line. DMRC reinstated the 80 km/hr speeds on the line in mid-2014. In Jan 2015, DMRC reported that the Airport Metro has recorded about 30 per cent rise in its ridership following the fare reduction of up to 40% in last July. r〔h〕 ==History== The first tenders for line construction were awarded in September 2007.〔(HCC-led JV bags Rs 774.64 cr Delhi Metro order – Economic Times ).

Services were suspended on 8 July 2012 due to a series of technical problems,〔(Business Line : Industry & Economy / Logistics : Delhi Airport Metro Express to resume services in two months: Govt )〕 including cracks in the girders, the iron beams that support the tracks; dislocated bearings that support the train; defective tracks and water seepage in tunnels.〔(Down To Earth: High-speed derailment )〕 The Urban Development Ministry subsequently disclosed that several clips in the underground section have been seriously damaged and it will take at least 5 months to rectify the problem. A joint inspection by Delhi Metro and Reliance Infrastructure team has revealed that 540 bearings need rectification and some girders which have cracked also need to be recast. The line reopened on 23 January 2013, operating at a reduced speed of 50 km/hr. The speed was gradually increased after inspections by the DMRC and other experts. At the reduced speed the time travel from New Delhi Metro Station to Airport was around 40–50 minutes. In the future it may be possible to reinstate original targeted speeds of 105 km/h if safe operation can be ensured. At present the line supports a speed of 80 km/hr providing for a 19-minute journey from New Delhi station to the Airport station. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Delhi Airport Metro Express」の詳細全文を読む スポンサード リンク
