For the first time since Chennai Metro Rail began operations six years ago, an extensive overhaul of trains has been planned to ensure that they continue to function without glitches and there is no derailment in future. According to officials of Chennai Metro Rail Limited (CMRL), they would start the process by next month. Since each train would require a month for the overhaul work, the officials plan to cover seven trains by the end of this year. From changing the bearings of motors to intensive cleaning of various parts, all aspects of a train would go through an overhaul, the officials said.
