Last year, the technology was used on Chongqing's urban rail transit lines and approved by authorities. It is now expected to be applied in dozens of other Chinese cities' subway systems.

"In addition to the next two generations of our urban rail transit signaling, which will be safer with even higher efficiency, our goal in the upcoming 10 years will be to research a sustainable intelligent operation mode of urban rail transit," Gao said.

"Urban rail transit projects usually require big investment for construction work and have high operating costs to maintain. A better mode that can cut costs will contribute to the entire public transportation system."

By mid-2017, a total of 31 cities on the Chinese mainland had urban rail transit lines totaling 3,965 kilometers, according to the China Urban Metro Transport Association. By the end of last year, it had reached 6,280 km in 38 cities.

Gao has never stopped his research work and is a man who loves challenges. Every time he has come up with a new idea, there have been questions and sometimes objections, but he always argues his case through his insights and hard work.

He is no miser with his ideas and has shared the company's technological advances with the whole industry. The company has published the full industrial standards of its signal system, which has led to faster growth of other players in the industry.

"We've turned signaling technology into commercial products and then a whole industry chain, which brings a sense of achievement for me," Gao said.

There are more than 10 listed companies with signaling integration qualifications, including his, in China, he said.

Gao said he has a close connection with the Zhongguancun Innovation Industrial Park.

"It always gives me incentives (to work harder) and people there have opened my mind," he said. "They are a group of people who dare to dream and try. I have gained much spiritual support from them."
