Spring Festival rush means more work, not rest, for some
The approach of China’s annual Spring Festival travel rush is one of the busiest times of the year for 42-year-old Zhu Ting and his team as they gear up to ensure railway safety using his self-created testing technologies.
With his system, there’s no manual work required to test the condition of rails — testing can be completed by an inspection vehicle.
Zhu, who graduated from Nanjing University in 1999, is a member of the research institute under China State Railway Group’s Shanghai branch.
“I have a passion for the railway and I hope to contribute to China’s railway reform, which I believe would be a grand stage for me,” Zhu said. “The development of China’s railway contains the dream of many technical workers, and I’m one of them.”
At the time, China was launching a large-scale speed-up and route adjustment on its railway network with many electrification projects, which led to a growing demand for monitoring the condition of the rails. Manual tests could no longer keep pace with the railway’s development but there was no scientific and efficient testing.
Zhu decided to take on the challenge of developing new technologies to solve the problem. Over the next two years, he shut himself in the lab, recording more than 80,000 pieces of experimental data and writing 10 volumes of notes.
After the research was complete, he began to put it into practice. To test the functions of devices he had built, he spent a whole day walking along the rails. When data showed there was abnormal abrasion, he reported it to a supervisor and later it was found that the problem was under a flyover and hard to detect because of the weak light.
It took Zhu and his team a decade for three generations of product development and application. Zhu’s products have been found to be more stable, more accurate and cheaper to produce than their foreign counterparts.
Zhu then set his eyes on the hump yard. A hump yard is a classification yard where railway cars are taken to a “hump” — an artificially built hill over which an engine pushes the cars — from where they are driven to classification tracks by the force of gravity.
In recent years, with the promotion of using railways for freight transport instead of highways, the transport of huge amounts of vehicles for sale transferred to the railways. Vehicles of a special size could not go through a hump yard. So Zhu’s team investigated, set monitoring points and collected data to work out plans to renovate the yards.
They also developed an all-purpose inspection car for high-speed trains.
