Days after the Delhi Metro faced a series of technical snags that disrupted services and caused overcrowding on several routes, the Delhi Metro Rail Corporation (DMRC) will start ultrasonic testing of rail welds to strengthen safety checks across its network. A tender was issued on October 7, seeking agencies for "Ultrasonic Flaw Detection (USFD) testing of Alumino-Thermic (AT) welds and rails (using B-scan machines for rail testing)" on six lines, including the Airport Express Line. The contract, valued at around Rs 1.89 crore, will be executed over a period of three years. As per the tender, the project aims to detect hidden defects in rails and welds that could otherwise lead to operational issues or safety risks. "Ultrasonic flaw detection will be utilised in metro systems for rapid, non-destructive testing (NDT) of rail tracks to identify internal issues such as cracks and corrosion," the tender read. Testing will be carried out on Lines 3 and 4, which are the oldest Blue LineDays after the Delhi Metro faced a series of technical snags that disrupted services and caused overcrowding on several routes, the Delhi Metro Rail Corporation (DMRC) will start ultrasonic testing of rail welds to strengthen safety checks across its network.
