Chennai Metro begins maintenance of trains to prevent glitches

According to officials of CMRL, the maintenance work, which has been done owing to the requirements of the original equipment manufacturer (OEM) maintenance manuals, involves removing the coaches and most of its components to check its working conditions.

Chennai Metro Rail Limited (CMRL) has begun overhauling of trains, an essential maintenance procedure without which there may be intermittent snags or even derailing. They finished this process for the first train recently.

According to officials of CMRL, the maintenance work, which has been done owing to the requirements of the original equipment manufacturer (OEM) maintenance manuals, involves removing the coaches and most of its components to check its working conditions.

“The first overhauling exercise will start usually five years after the trains are pressed into service. After that it becomes a continuous cycle. For each train, it will take about 40 days and over the next year, we hope to finish overhauling at least seven trains. For each train, we will be spending ₹1.77 crore,” an official said.
