Zero tolerance for millimeter-level hidden dangers, rail inspection builds a solid safety defense line It is reported that on March 10, the national railway spring equipment inspection was fully launched. In the Xuzhou section of the Beijing-Shanghai Railway, inspectors operated portable testing equipment to move slowly along the rail surface, and the screen displayed real-time fine lines on the surface of the steel rails. A person in charge of the railway department introduced that as the "lifeline" for train operation, railway tracks are long-term subject to the impact of train loads, changes in day and night temperature differences, and erosion by rain and snow, which are prone to hidden dangers such as cracks and wear. If not handled in a timely manner, small damages may lead to rail breakage accidents.

Zero Tolerance for Millimeter-Level Hidden Dangers, Rail Inspection Builds a Solid Safety Defense Line This newspaper reports On March 10, the nationwide spring equipment inspection for railways was fully launched. In the Xuzhou section of the Beijing-Shanghai Railway, inspectors operated portable testing equipment to move slowly along the rail surface, with the screen displaying real-time fine lines on the surface of the steel rails. A person in charge of the railway department introduced that as the "lifeline" for train operations, rails are subject to long-term impact from train loads, changes in day-night temperature differences, and erosion by rain and snow, which can easily cause hidden dangers such as cracks and wear. If not handled in a timely manner, small damages may lead to rail breakage accidents. "A tiny crack of 0.1 millimeters on the surface of a steel rail can expand at a rate of 2-3 millimeters per month within 3 months under repeated rolling by trains," according to the inspection data displayed by on-site technical personnel. With the help of the online detection system for rail surface damage, defects such as rail surface scratches and pitting can be accurately captured, and the development trend of damage can be predicted in combination with AI algorithms. Statistics show that 85% of unplanned train stoppages caused by rail damage in China's railways each year stem from tiny hidden dangers that were not discovered in the early stage. Regular inspections can reduce such risks by more than 90%, which not only ensures the safety of passengers but also reduces economic losses.
