Pajares
tunnel
The Pajares tunnel is the most com-
plex and difficult project executed
in Spain to date. Thanks to this
project, the Principality of Asturias,
which had been demanding this rai-
lway since the 80s, no longer lacks
railway connection with the rest of
the country.

Connection of the Atocha and Chamartín railway stations in
Madrid. The project involves a two-lane, 7.3 km long tun-
nel, 6.9 km of which are underground, connecting the Ato-

street, crossing several subway lines along the way. The
project makes it possible to connect trains arriving to and
from the south of Spain with those from the northern half of
the country.
