Japanese National Railways class ED76
Japan 1965 139 produced
The ED76 is an electric locomotive for passenger and freight service with three bogies, only two of which are powered. The base model was the series 0, of which 94 were built. The 22 locomotives of the series 500 had a longer car body because the water and fuel tanks for the train heating had been enlarged. They had gangways at the fronts because they were often used in pairs. One example was adapted for the Seikan Tunnel and formed the series 550. 23 locos for express freight service formed the series 1000. In 2016 only ten locos were still in service, all owned by JR Freight.
