The New Delhi-Varanasi Vande Bharat Express was taken out of operation on Saturday after it suffered a snag in a traction motor that jammed its wheels and damaged their perfect roundness, a situation officials described as "flat tyre". However, due to development of a flat tyre of 80 mm, the train has been moved at a restricted speed of 20 kmph up to Khurja...A detailed investigation of the failure will be done after taking the rake back to maintenance depot,'' the statement said. A traction motor is an electric motor used for the propulsion of a system such as locomotives, electric or hydrogen vehicles, elevators or electric multiple units. An undetected bearing failure may cause serious accidents. "At aorund 12:40, all the 1,068 passengers were deboarded and shifted to a Shatabdi Express rake which was brought from Delhi for their onwards journey," an official said. A 'flat tyre' in the railway terminology refers to the damage to the perfect roundness of the wheel with some "flat" places in its periphery. #vandebharat Source:-MoneyControl
