Case Study of Energy Efficiency in Railway Operations

Utilization of AI in the Railway Sector

Highlight

Leveraging its past track record in rolling stock maintenance of high-speed Class 395 rolling stock for the UK’s High Speed 1 project, for which it received orders in 2005, Hitachi is advancing the expansion of its services business in the railway sector, for example, through the UK’s Intercity Express Programme (IEP) and by providing rolling stock maintenance for Abellio, a railway operator. Condition monitoring systems that remotely monitor the condition of rolling stock will be the key to expanding and developing the services business. Hitachi is working on utilizing AI technology that it has developed to provide further added value using rolling stock information that is collected on a daily basis. This article covers power consumption while operating railway rolling stock, and presents an analytical case study of where feature values for reducing power consumption are identified using AI.
