The Renfe Class 321 (formerly 2100 series) is a class of diesel-electric locomotives operated by Renfe in Spain, designed by Alco and built by them and by Euskalduna under licence.

Technical specifications

[edit]

The locomotives have a Co-Co wheel arrangement, and are equipped with GEC 5G-761 engines.[2]

History

[edit]

Production started in 1965. A total of 80 locomotives were built until 1971,[3] with the first eight built by Alco, and the remaining 72 by Euskalduna.[4] Four locomotives were rebuilt for Teco de Media Distancia freight service trials.[2]

Regular services with Renfe have ended, and some locomotives are used by Adif to haul maintenance trains.[4]
