The 'Top 10 Railway Technologies Award' is an annual recognition by the Korean Society for Railway, which selects ten outstanding railway technologies each year. The competition is known to be fierce, with significant participation from railway operators, research institutes, and related companies.

This year, the corporation submitted three technologies: the next-generation rapid power outage monitoring device for urban railway overhead lines (independently developed), the LTE-R network-based smart preventive inspection system for railway vehicles (jointly developed with Woojin Industrial Systems), and the world's first rotary-type current collector (jointly developed with the Korea Railroad Research Institute). All three technologies were named among the top ten.

The next-generation rapid power outage monitoring device is equipment that monitors the application of DC system power in real time and instantly detects the occurrence of rapid power outages. During field application, it has been credited with enhancing the operational safety of urban railways and reducing the risk of electric shock accidents. The corporation analyzed that it saved approximately 270 million won in budget through in-house development.

The LTE-R-based smart preventive inspection system is a big data platform that transmits and stores key train equipment data and operational records in real time via the railway wireless communication network. Since the headquarters, control center, and train depots can share the same data, the accuracy of failure prediction has been greatly improved. The technology is currently applied to Busan Metro Line 1, and similar technology will be introduced to the new trains being manufactured for Line 2.

The world's first rotary-type current collector was developed to address the frequent pad replacement issue in rubber-tired light rail vehicles. If the pad position shifts due to impact or vibration, the device rotates without additional power, maintaining stable current collection performance. It also ensures even pad wear, which is expected to reduce replacement costs.

Lee Byungjin, President of Busan Transportation Corporation, stated, "This achievement is the result of our ongoing investment in technology development to enhance urban railway safety," adding, "We will continue to prioritize safety and citizen convenience as our core values and lead the development of future railway technologies."
