Study of Asset Management Method for Galvanized Steel Railway Electrification Infrastructure in JR-EAST

As sea wind and acid rain gradually corrode galvanized steel, it is necessary for galvanized steel railway electrification infrastructure to be overpainted or rebuilt for long-term use. Maintenance policies such as painting or rebuilding are currently decided by maintenance engineers' experience and knowledge. It is not always cost-effective. Therefore, the authors have studied the application of the asset management methods for galvanized steel railway electrification infrastructure maintenance. We made an experimental asset management calculation tool. Using sample data, we concluded that the asset management methods are helpful in finding the most cost-effective maintenance policies.
