History

Originally classified by RENFE as 76xx and 86xx (the example in the photograph is number 7685), the 276 series was based on the French SNCF Class CC 7100. The majority of the 276s were manufactured in Spain by various locomotive works, including Construcciones y Auxiliar de Ferrocarriles. Due to their Gallic origins, the locomotives were given the nickname "francesa" (approximate English translation: "Frenchie").A total of 136 units were built during the years 1956 and 1965, ten of which were modernised and classed as 276.2xx.

Technical Data

Since the 276 is a Co'Co' locomotive, it is equipped with two three-wheeled bogies – each of which is powered by three engines. This six-engine configuration provides the locomotive with a total power output of 2,200 kilovolts and a maximum speed of 110 km/h (approximately 68 mph). Out of the 136 examples produced, only 36 have been adapted for use in MU operations, these are unit numbers 276.101 through 276.137, inclusive.

Current status

At the present none of the locomotives from this series are in service.
