Chinese railway operators used smart facilities to bolster safety during the 40-day Spring Festival travel rush, which began on Feb 2. To ensure the safe transport of coal from coal-rich Shanxi province, the Taiyuan Engineering Machinery Section asked its employees to conduct inspections with smart facilities on lines within its jurisdiction. Equipped with a high-precision flaw detection system, its rail-flaw detection vehicles can accurately identify surface and internal damages to rails. Through the professional analysis and judgment of operating staff members, it can provide solid support for the safe operation of trains during the travel rush.
