  250 601 in July 1987

Technical specifications

The locomotives have a C'C' UIC wheel arrangement, ^[3] and are equipped with monomotor bogies, which have switchable gear ratios. ^[2] Their maximum axle load is 22 tonnes. ^[1]

History

The locomotives were introduced in 1982. A total of 40 locomotives have been built. They were mainly used on freight services by Renfe's Cargas freight and Transporte Combinado intermodal divisions. ^[2]
