Hitachi received an order for two energy storage devices for Traction Power Supply Systems through from MTR Corporation Limited (“HONG KONG RAILWAY”), a railway company in Hong Kong. The system will be delivered by November 2015 and will start operation after February 2016. This will be the first time that lithium ion battery-applied regenerative braking will be installed in Hong Kong's railway systems.

In an effort to save energy, Hong Kong Railway is considering installation of systems for both onboard and wayside systems in order to reduce power consumption and increase of power efficiency of railway operation as a whole. Each waywide system will be installed in each line's substation.

The system will include two lines; the one is to Airport Express Line connects Hong Kong and Kowloon to Hong Kong International Airport situated off Lantau Island (total operating distance is 35 km.), and the other is to Tsuen Wan Line connects Central Station to Tsuen Wan Station situated in southern new territories. After one year validation of energy saving effects, the system is expected to widely adopt to HONG KONG RAILWAY's lines when commercially viable.
