three retired train cars from Melbourne’s suburban railway network are on top of a three story building, and are a restaurant

These trains are known as Hitachi trains because the electrical equipment was supplied by Commonwealth Engineering, with designs by the Hitachi company of Japan. The stainless steel Hitachi cars were the city’s first suburban trains with power-closing doors and heating.
