Empalme serves as a division point and the hub of Ferromex operations in Sonora. From here, crews work north to Nogales and Benjamín Hill (trains destined to Mexicali), west to the port of Guyamas, and south to Sufragio. Virtually all trains terminate here and are reswitched.
After the northbound D SFEM (Directo Sufragio-Empalme) has arrived in Empalme Yard, the crew is getting a ride to the depot.
The yard switcher is running down the mainline in order to switch out the inbound cars. The road locomotives will pull high on the mainline allowing the switcher to duck into the yard.
A DEMSF is approaching the end of yard limits while departing Empalme southbound. The train is being pulled by a single Super 7, running long-hood forward.
At Guasimas, a southbound manifest train trundles down the mainline.
Sufragio is Ferromex's main hub in northwestern Mexico. Manifest trains from Guadalajara arrive here, and are switched out for various destinaltions. Trains then depart northward to Empalme and Chihuahua while locals run to Los Mochis, the port of Topolobampo and Navojoa.
South of Sufragio, the FC Pacifico passes through the agricultural coastal plains toward Culiacán. At a point south of Culiacán, the Sierra Madre become steep and hug the coast, so the tracks turn downhill and run toward the coastline. For about 40 miles north of Mazatlán, the tracks run along beaches and through coastal towns much as the SP Coast Line and the ATSF Surfline (although a much more desolate area).
