A decade on, high-speed rail still delivering in western China

Ma moved from his hometown in Henan province to live in Xining, the capital city of Qinghai, with his parents when he was 7, as his parents were also railway employees working in the province.

He majored in clinical medicine in college, but influenced by his parents, learned a lot about railways and passed the examination to join the China Railway Qinghai-Xizang Group in 1996.

Ma and his team are responsible for the inspection and maintenance of high-speed railway bridges, tunnels, culverts and other critical equipment. They usually work between midnight and 4 am when the train traffic is relatively light.

Despite working at an altitude of more than 3,000 meters for the past 28 years, Ma hasn't missed a single inspection or made an erroneous judgment.

The team needs to promptly identify and address problems and hidden dangers along the route such as whether drainage outlets within protective fences are blocked, if there is floating debris, or if local residents are engaging in activities like burning waste or building sheep pens along the route's fence line.

The environmental issues along the rail line also fall within their scope. In the first few years, Ma and his team encountered villagers dumping piles of straw along the rail fences or burning waste. When they tried to dissuade them, the villagers often didn't understand and refused to cooperate, making the work difficult. They had to collaborate with village officials to address these issues.

The area is prone to strong winds, and debris on the tracks can affect train safety, Ma said. In recent years, increased rainfall and haphazard construction have led to poor drainage, also impacting safety.

After 10 years of operation, the residents around the railway tracks have developed a basic awareness of safety and understand the significant benefits of the railway's safe operation for the local community, he said.

"In maintaining the railway's normal operation, great responsibility, patience, a strong will to keep learning and a continuous spirit of innovation are required," said Ma.
