A day after suspending operations for an indefinite period at the Delhi Airport Metro Express, due to safety issues, the government today assured the public that it will be reopened once necessary repairs are complete.
Reliance Infrastructure reported that there are some defects in the civil structure. There are problems with the bearing which is the interface between the pillar and girder. Repairs words need to be done below the girders and it is in odd kind of locations, informed Sudhir Krishna, Secretary, Urban Development.
The 23-kilometre-long Delhi Airport Metro Express is one of the country’s fastest metro corridors where trains run at speeds of 105 kilometres per hour. The line is barely 16 months old.
Reliance Infra operates and maintains the corridor, but the civil structure was built by the Delhi Metro Rail Corporation (DMRC). Over 10 percent of the bearings, that’s about 230 out of 2100, need repair.
Reliance Infra says the defects first surfaced during the annual inspection in May 2012 by the operator, Delhi Airport Metro Express, a subsidiary of Reliance Infra. The operator then reported the defects to the DMRC, the Government of India and the Government of Delhi early in June 2012.
Following the serious concerns raised by the operator regarding safety, speeds on the corridor were reduced to 25 kilometres per hour. The DMRC admitted the defects in the civil structures and has agreed to carry out necessary rectifications.
A committee comprising officials from the Indian Railways, Delhi Metro and Reliance Infrastructure is already going into the nature of defects and would submit a report within the next 10 days.
