These seven Estado locomotives were assigned to the Ripoll-Puigcerdà - La Tour de Carol Transpyrenean Railway line to provide a mixed passenger and freight service. They were built in 1927 by C.A.F. (Compañía Auxiliar de Ferrocarriles), and received their electrical equipment from C.E.F. (Constructions Électriques de France) of Tarbes. They were very similar machines to the E-4001 to E-4040 units of the French Midi company. The machines initially received a grey-green color because at that time the main base of the paint was white lead, a lead pigment that made exterior paint more durable.
In early 1964, the voltage transformation from 1,500 to 3,000 volts of the locomotives began at the MACOSA factory (Societat Material i Construccions S. A.) in Valencia, with the electrical part handled by the Swiss company Ateliers de Secheron. With the voltage change, the pantographs were replaced, multiple-unit control was disabled, they were equipped with a high-speed electromagnetic circuit breaker, the traction motors were adapted to 3,000 volts, and the minimum and maximum relays were changed.
Locomotive 1006 left for conversion in November 1965 and returned to Ripoll in October 1966, following test runs carried out between Tarragona and Móra la Nova hauling a coal train, for which a driver and an assistant from the Ripoll depot were dispatched.
They were always on the Ripoll to Puigcerdà line, and sometimes they traveled to the Barcelona-Vilanova workshop for some repairs. The last regular service of the Omnibus Correo No. 1901/1902 between Ripoll and Puigcerdà was carried out by locomotive 1006 on September 25, 1982, when the Correo was discontinued. From that day on, they only made sporadic services with work trains, some freight, and if it snowed, they went out to explore the tracks. Their end was hastened in 1987 with the inauguration of the Cerdanya Pullman service, as locomotives from series 279, 289, and 269 were authorized to run on the line. In February 1993, RENFE ceded locomotive 1006 to the Ripoll City Council. Locomotive 1002 was destined for scrapping, but it was in good condition, completely intact and with all four traction motors, so they decided to swap their plates. Thus, the original 1002, which actually carries the numbering of the 1006, was displayed on the pedestal at the Ripoll station. The other locomotive, missing most of its components, was set aside, and RENFE sold it to a scrap dealer. The dealer decided not to dismantle it because that intervention would have cost more than abandoning it on a dead-end track.
Finally, in 2022, the City Council of Sant Joan de les Abadesses commissioned the aesthetic restoration from the Móra la Nova Museum.
