The Ferrocarril Chihuahua al Pacifico (Chihuahua-Pacific Railway), also known as El Chepe from its reporting mark CHP, or Ferrocarril Chihuahua-Pacifico 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.
The tracks pass over 37 bridges and through 86 tunnels, rising as high as 2,400 m (7,900 ft) above sea level near Divisadero (the continental divide), a popular lookout spot over the canyons. Each one-way trip takes roughly 16 hours. The track also crosses over itself to gain elevation.
