The locomotives series 7400 were designed for the electrification (1500v) of the Madrid-Ávila-Segovia lines in the 1930’s. However, the project was executed in the 1940’s, after the Spanish Civil war. The 7400 series with a Co-Co wheel arrangement were intended for passenger and goods transport and built by the Swiss Company Sécheron (electrical part) and the Spanish Company DEVIS (mechanical part). They started their duty between 1944 and 1950 in the “Principe Pio” depot. Nevertheless, they carried out some interim services in the León-Ponferrada line. As in 1972 the electrical power conversion (from 1500v to 3000v) in the lines where the series were running, they were moved to the “Miranda de Ebro” depot, running in the Miranda – Irún, Miranda – Bilbao, and Miranda – Burgos lines. In 1984 the 7400 series finished their duty after the electrical power conversion in the Miranda de Ebro’s lines.
