- Pajares Base Tunnel
The new Pajares Tunnel is a 24,667 m-long
railway tunnel under construction inSpain . It will be onAVE line fromValladolid toGijón but could be used also by freight trains in the future.Standard gauge and
25 kV AC electrification will be used, so freight trains will probably not use the tunnel from the beginning. Only when, and if, Spanish network will be converted tostandard gauge freight will use the Pajares Base Tunnel.External links
