We have supplied products to many railway operators at home and abroad. Whether manufactured by us or by other companies, previously delivered equipment is now due for replacement or renewal. Furthermore, new railway lines are expanding, including the construction of new lines such as the Shinkansen projects in Japan.
Furthermore, the methods or techniques of Condition-Based Maintenance (CBM) and overhead line inspection, both essential for safety, are evolving. In this context, we continue to conduct research and development to contribute to reducing environmental impact.
　This special issue introduces electric railway systems contributing to safety, stability, and environmental impact reduction.
