The Plazaola Train: History and Infrastructure

Discover the Pamplona–San Sebastián (PSS) railway, the mining and passenger train that travelled through the rugged valleys of Navarre and Gipuzkoa between 1905 and 1953.

In 1914, a modest mining train became an ambitious narrow-gauge train linking Navarre and Gipuzkoa via the shortest, most direct route: the Plazaola Railway, Pamplona-Lasarte-San Sebastian, which went through places like this one called Paso de Dos Hermanas.

At the beginning of the 20th century, the Larraun and Leitzaran valleys were rural areas, where all means of transport were animal powered, and journeys were basically local, to meadows and hills.

The Bizkotx iron deposit, the largest in Gipuzkoa’s Leitzaran Valley, gave rise to the railway. It was necessary to transport the mineral from the mine, later called “Plazaola,” to steel mills and ports. This led to the construction, in 1905, of the first mining train.

On April 21st, 1905, the first mining rain want up from Andoain to the Plazaola mines. A grand occasion that deserved as much solemnity as possible, with the first locomotive being decorated with flags and banner-like tree branches.

On January 25th,1914, the first train was eagerly awaited in Pamplona. From that year onwards, those first mining convoys reached the Navarre capital, now converted into passenger and freight trains. Pamplona was thereby linked to San Sebastian by train with a journey time of just three hours.

The Infrastructure

The mining train’s first and most fragile structures were used for the new passenger railway, like this first metallic Auzokalte viaduct, built with beams featuring iron latticework. In 1943, it was replaced with an impressive concrete viaduct.

A series of tunnels and bridges run through the ravines. However, exceptionally, the longest bridge was to be found in easy terrain near Pamplona. The Gulina viaduct crosses a stream on a 135-metre-long stone structure, supported by 17 arches 13 metres above the watercourse.

Water, along with increasing road transport using buses and lorries, was the main enemy. In 1953, a devasting storm destroyed the line and put an end to the Plazaola railway. Even earlier, in 1931, a flash flood washed away the bridge over the Arga, in Pamplona, which had to be rebuilt.

The flash floods of 1953, which finished off this railway, are present in the memories of the longed-for Plazaola train’s former passengers.

In many sections, it was a real feat to lay down the tracks. In some cases, it was necessary to scrape the crags, like this one called Txapela de Bertxin, hanging above the Leitzaran ravine not far from Andoain in Gipuzkoa.

The rugged terrain and the numerous meanders of the Leitzaran stream made it necessary to build dozens of tunnels: up to 66 were drilled. Among them all, the 2,630-metre-long Uitzi Tunnel stands out –for many years its was the longest in Spain’s narrow-gauge network.

The waters of the Leitzaran, which carved out the narrow valley through which the Plazaola railway ran, have long been used to generate energy, in foundries and electric power stations. Stone aqueducts, like this one of the Amerauan Power Station, were erected to transport the water to the turbines.
