Preventive and predictive maintenance of electrical components for railroad vehicles to help extend product service lives

Toshiba Infrastructure Systems & Solutions Corporation* / Toshiba Infrastructure Technology Service Co., Ltd.

As global resource and energy consumption as well as waste generation increase, the world is moving toward a circular economy that uses resources sustainably, with a growing emphasis on minimizing waste and extending product service lives.
Preventive maintenance of electrical components for railroad vehicles plays an important role in extending the lifespans of such vehicles. Since railroad vehicles are used for 20 to 30 years or longer, it is necessary to prevent the deterioration and failure of their electrical and electronic components. Toshiba Infrastructure Systems & Solutions Corporation and Toshiba Infrastructure Technology Service Co., Ltd. use predictive detection and prediction technology to handle the aging of parts. And Toshiba Infrastructure Systems & Solutions Corporation and Toshiba Infrastructure Technology Service Co., Ltd. propose preventive maintenance through repair and replacement of parts to railroad operators in Japan and abroad in order to extend equipment service lives. We also improve performance by adding features that employ the latest technology and by updating equipment.
Moreover, we offer solutions that leverage vehicle data to visualize moving vehicle data and to reduce maintenance labor. By utilizing advanced technologies such as generative AI, we aim to reduce maintenance labor through failure prediction and deterioration diagnosis, and contribute to solving management issues such as the shrinking labor force and how to reduce costs.
