High Quality Content by WIKIPEDIA articles! Hitachi is the name given for one of a set of electric multiple unit trains that operate on the suburban railway network of Melbourne, Australia. Introduced to service in 1972, the trains are the oldest in the city`s suburban fleet still in revenue service. Electrical equipment was supplied by Commonwealth Engineering to designs by Hitachi of Japan, leading to their official name today, though no actual Hitachi-supplied components were used in their construction. Hitachi trains have been also known as Martin & King or Stainless Steel trains officially, and are one of the few trains still in operation that allows windows to be opened.
