On April 23, 1911, what came to be known popularly as the “El Irati” railroad in Navarre–a 36-mile-long railroad connecting Pamplona-Iruñea to Zangoza and Agoitz (Aioz)–was inaugurated. It was the first electrified railroad in Spain, and indeed among the first in Europe, and it would operate until 1955.

It was conceived originally as a means of aiding development of the lumber industry in the Irati Forest (today a major tourist destination in Navarre) and in particular the major sawmill in Ekai de Lónguida/Ekai-Longida. However, it also became an important passenger line, especially for people traveling between Zangoza and Agoitz. Although plans to develop a railroad in the area went back as far as 1868, it was not until 1900 that they were taken up again seriously–this time concerning an electrified railroad–by local entrepreneur Domingo Elizondo, the principal developer of the lumber industry in the Irati Forest. With the support of the Provincial Council of Navarre, Spanish government approval was conceded to the project in the years 1907-8, and the El Irati company was created to oversee the project. The railroad itself was subsequently constructed between 1909 and 1911.

For the next thirty years it functioned successfully. A 1941 study calculated that the railroad transported an average of over 240,000 people and 46,000 tonnes of goods a year. At about this time, it began to decline in terms of passenger numbers as buses became a more and more typical site in rural Navarre. By the mid-1950s, its losses were significant enough to force the El Irati company to write all the city councils of the towns through which it passed asking for financial aid to keep the railroad running. Failing to get the sufficient financial support, though, the line was closed definitively on December 31, 1955.

Nowadays, where part of the railroad once ran there is the Greenway of the Gorge at Lumbier-Irunberri, a 4-mile trail for hikers and bicyclists to enjoy. Since 2013, however, work has been ongoing in developing this track further to encompass much of the original length of the railroad in a trail measuring over 28 miles in total and running from Uztarrotz  to Zangoza.
