Junio 28, 2009. L??????neas f?????rreas de Tierra Blanca, Veracruz, M?????xico. Migrantes centroamericanos en espera de la salida del tren hacia el norte.
When the whistle of the train goes, migrants grab their backpacks and water bottles and run.
The trains have no set schedule, and migrants waiting by the tracks often jump aboard a moving car, an act that has injured many and even cost some their lives. Robbery, beatings, rape, and extortion are among the other potential perils of the trip.
