Not just the bearings, but a large number of rail clips in the tracks of airport Metro express’s underground section have also developed cracks, reveals a recent check conducted on the track system by Airport Metro Express Pvt Ltd (DAMEPL), a subsidiary of Reliance Infrastructure.
The clips join the rail with the concrete slabs on which the tracks are laid.
According to the concessionaire, the clips have been breaking for a long time. Many clips were found broken which were replaced by the DAMEPL from time to time. A joint team of experts from DAMEPL, Vossloh-Patil (the company that manufactured the clips and provided the technology) and DMRC has been studying the issue. But the exact cause of the breakage is yet to be identified.
Reliance Infrastructure has blamed the Delhi Metro on the issue. “Though the tracks were laid by us, we used the technology provided by Vossloh-Patil, Germany-India joint venture, which was referred by DMRC,” said a Reliance official.
SD Sharma, director, Business Development, DMRC, however, said: “The performance of this company was tested and so we suggested it in the DPR as per the guidelines laid by Indian Railways.”
An urban development ministry source said, “We are investigating the problems reported by the concessionaire.”
