"However, it will be done by M/s DAMEPL, the concessionaire and operator of the Airport Metro Express Train," Minister of State for Urban Development Saugata Roy said in a written reply in Rajya Sabha.
"The average ridership of the Metro Express Line was about 17,000 passengers per day as on the date of shut down of train services," he said.
Roy said prima facie, the investigations show that there are defects in civil works, "such as crushing of grout material above and below bearings, cracks and shifting of bearings at many locations. In addition, certain cracks and twist in some of the girders have also been noticed."
