Using superconducting materials for railway transmission cables, it will be possible to reduce power loss, level the load between substations, and consolidate substations by suppressing voltage drops. Herein, we focus on the trajectory of “commercial line operation” in response to the 2024 Impact Award from the Cryogenics and Superconductivity Society of Japan. Following a series of fundamental superconductivity experiments, we report on the testing and operational status of the superconducting feeder system at a passenger railway company.
