CHP #754

The Ferrocarril Chihuahua al Pacífico (Chihuahua-Pacific Railway), also known as El Chepe from its reporting mark CHP, or Ferrocarril Chihuahua-Pacífico is a major rail line in northwest Mexico, linking the city of Chihuahua, Chihuahua, to the city of Los Mochis, Sinaloa and its port Topolobampo. It runs 673 km (418 mi), traversing the Copper Canyon, a beautiful and rugged series of canyons that have led some to call this the most scenic railroad trip on the continent. It is both an important transportation system for locals and a draw for tourists.
