Data from [], the web site of the Spanish National Railway.
Justo Arenillas in "Las locomotoras belgas en el Madrid-Caceres-Portugal", Lineas Del Tren (as reproduced on [], viewed 28 April 2003) said (as translated by Locobase) these were the last Belgian locomotives to be bought by a Spanish railway. These replaced the 0-6-0s that Couillet had delivered years earlier, but were in turn supplanted by the passenger Garratts of a few years later. Arenillas comments that the tall drivers, tallest among the Mastodons, are surprising given the steep profiles of the FCA's routes.
A description of the locomotives held by El Museo del Ferrocarril de Vilanova i la Geltru comments that these "Mastodontes" were the largest non-articulated locomotives to be bought by the FCA. It explains that replacing the 0-6-0s was mandated not just by the increasing size, but also the increasing speed of the passenger trains. Echoing Arenillas, the catalogue notes the dual requirements of being able to confront the steep grades while also pulling fast trains on the level.
In the 1950s, the class was transferred to the Tarragon depot to serve local freight and passenger traffic.
