It was around 1885 when the powerful Compañía del Ferrocarril del Note, which operated, among others, the Zaragoza-Miranda line, opened the modest narrow-gauge railway that linked its station in Tudela with the Zaragoza town of Tarazona.

This entire railway project was more than modest. The narrow-gauge layout (1 metre) was in line with the few relief features that dotted the flat Queiles Valley. The rolling stock was simple and gradually deteriorated without the company doing much to restore it.  The anecdotes about its inefficiency gradually became a hallmark of this valley.

After the Spanish Civil War, the line’s situation was more than pathetic. Thus, Renfe had to undertake a thorough reconstruction of the route, in such a way that it even changed the gauge of the track, adapting it to the general Iberian network. In 1953 the line was reopened in excellent operating conditions. Despite this, buses had already taken over passenger transport, and trucks and cars were beating the railway on almost all fronts.

After a few years of unstoppable decline, in 1970 regular freight traffic was abolished, with the line specializing in passenger services. But the latter did not last much longer, since two years later the entire train service was closed once and for all.
