This little tank was dubbed Somorrostro when it entered service. It was the odd one out among the RENFE holding of small tank engines in having fewer tubes of smaller diameter. Like the others, the 17 served the Bilbao-Portugalete suburban lines until electrification in the 1930s. It then operated in auxiliary service into the 1960s.
