The locomotives were acquired by Renfe to replace steam engines on lines in Andalusia, La Mancha and Extremadura, and were designed to be able to operate on lines that required a low axle load.[2] The fifty units were numbered 313–001 to 313–050;[1] 40 were constructed under license by Euskalduna, the remainder by Alco.[1]
The locomotives were initially supplied in yellow striped Renfe green livery, some units later received Renfe yellow grey after refurbishment.[2]
