Valladolid - Venta de Baños - Palencia - León Line

Contributing to the socioeconomic structure of the Autonomous Community of Castile and León


When this line comes into service, the capitals of Palencia and León will be included in the Spanish high-speed network. It will also favour connections towards Asturias (via León), Cantabria (via Palencia) and Burgos and the Basque Country (via Venta de Baños).

It also contributes to the socioeconomic structure of the Autonomous Region of Castile and León, and reduces the journey time between Madrid and the provincial capital of León.

European Funding

Adif AV has received aid and financing for this line from the various European Union (EU) funds and programmes.

Description of the line

Quality service

The new Valladolid - Venta de Baños - Palencia - León connection, which went into operation on 30 September, 2015, is 166 km long and is designed so that trains can run at a maximum speed of 350 km/h, with standard or UIC gauge track (1,435 mm), electrification at 2x25 kV 50 Hz in alternating current, typical of high-speed trains.

It is designed to support passenger and freight traffic.

Its route is not as conditioned by the abrupt orography of the terrain as the rest of the lines of the North-Northwest Corridor. 

Important infrastructures
  • One tunnel (Peña Rayada, 1,998 m) and one false tunnel (Villamuriel de Cerrato, 350 m).
  • 48 viaducts / pergolas, to bridge other infrastructures at different levels.The viaducts over the Pisuerga River (1,331 m) and the Esla River (660 m), or the Torneros pergola (León), 606 m long, particularly stand out for their length.
  • A Maintenance Base for the line in Villada (Palencia)
  • The Venta de Baños Triangle, which will facilitate all direct traffic connections that are possible between Valladolid, Palencia, León and Burgos.
Gauge changers

The line has three gauge changers: one in Villamuriel (south of Palencia), to enable traffic on the Iberian gauge up to Cantabria; and two near León station, to ensure traffic on the Iberian gauge up to Asturias and Galicia.

Stations on the line

Adaptation of Palencia station

The adaptation has involved the complete renovation of the platforms, which have been widened, resurfaced, repaved and fitted with canopies. Accessibility has also been improved: access to the central platform has been improved by installing lifts next to the existing underpass, which has also been remodelled.

The new Palencia station includes two standard or UIC gauge high-speed tracks (the ones nearest to the passenger building), and two conventional gauge tracks.

León station

Adaptation of the High Speed line to the Conventional Network double track between Onzonilla and León station, including the renovation of the track-bed, superstructure, electrification, safety elements and two new gauge changers. Two new siding tracks have also been built in the León station, which now has two conventional gauge tracks (high speed) and two Iberian gauge tracks.

Environmental measures

The Ministry of Public Works and Adif Alta Velocidad are promoting the development of a truly sustainable and nature-friendly railway, where the maximum respect for protected natural areas is maintained during the design, construction and operation of the railway infrastructure.

In addition to ensuring compliance with the Environmental Impact Statement (EIS), the level to which the works are integrated into their surroundings and the effectiveness of the environmental measures adopted during the works are assessed from a global perspective.

All the measures are intended to reduce the impact of constructing the new line, while strictly respecting the ecosystem of the areas through which it runs, and minimising its visual, noise and landscape impact.
