Core Viewpoint - The article highlights the critical role of track inspectors, specifically focusing on the work of He Zhiwen, who conducts ultrasonic testing on high-speed rail tracks during the night to ensure passenger safety during the busy Spring Festival travel period [1][6]. Group 1: Track Inspection Process - The inspection is conducted during the "downtime" of trains at Foshan West Station, where the increased train volume during the Spring Festival poses significant challenges to track equipment [1]. - He Zhiwen uses an ultrasonic testing device to analyze waveforms, checking for internal damages in the heart rail, which is crucial for the safe operation of trains [1][4]. - The heart rail, being only 5 centimeters at its narrowest point, requires precise handling of the testing equipment, often needing the inspector to maneuver in tight spaces [1]. Group 2: Operational Details - The inspection process includes placing protective wooden blocks, grinding the rails to ensure a smooth surface, and applying coupling oil to enhance the effectiveness of the ultrasonic testing [3][4]. - He Zhiwen and his team utilize various probes and perform multiple checks on different parts of the heart rail, including the rail surface, side, and angle, to ensure comprehensive coverage [6]. - After completing inspections on multiple switches, He Zhiwen confirms that there are no damages found, ensuring the safety of the rail infrastructure [6].
