A 25 km long railway tunnel
A consortium of Alstom and Isolux Corsán has been awarded a €28m contract to design, supply and maintain 25 kV electrification, including the traction substation and overhead line equipment for the 44·3 km route under construction between La Robla and Pola de Lena.
The new Pajares Tunnel is a 24,667 meter long railway tunnel under construction in Spain. It will be on the AVE line from Valladolid to Gijón but could be used also by freight trains in the future.
The tunnel will cut the distance by rail between León and Oviedo by 33 km and enable the maximum speed to be raised to 300 km/h from the current average of 60 km/h.
