A report says that on the morning of September 15, China's first railway track trunk line with full-process intelligent monitoring functions was officially put into operation in East China. At the ceremony site, a Fuxing bullet train smoothly passed over the new type of railway track, with the track surface reflecting the clear blue sky, and the micro monitoring modules embedded in the track waist, like "nerve endings", capturing operating data in real time. The line has a total length of 286 kilometers, and each meter of the track is equipped with 3 high-precision sensing modules, which can simultaneously collect 12 key indicators such as vibration, temperature, stress, and displacement, and transmit them to the cloud management platform in milliseconds through 5G + edge computing technology.

Compared with traditional steel rails, the new-type rails are made of high-manganese vanadium-titanium alloy, forged at a high temperature of 1200℃ and precision-rolled, with their wear resistance improved by more than twice. The supporting AI crack early warning system is equipped with a deep learning algorithm, which can accurately identify tiny damages at the 0.1-millimeter level, automatically generate maintenance work orders and dispatch them to the nearest work sites. According to the person in charge of the railway department, after the smart rails are put into use, the frequency of manual inspections has been reduced by 70%, the inspection efficiency has been increased by 80%, and the maintenance cost has been reduced by 30%, which will build a solid technological barrier for the high-density and high-speed operation of high-speed railways.
