Migrants wave goodbyes and victory signs as they board a train headed north. The train hand’t passed through in five days and many were anxious to continue their journey. About two-thirds of the residents at La 72 Migrant Shelter, a little over 100 people, boarded the train as it passed through Tenosique. Migrants face extortion, robbery, rape and kidnapping on top of these trains. The Mexican government announced in July a plan to use law enforcement to keep migrants from using the trains to get the U.S. border. July 25, 2014.
