Federal Police_Aug 26_2014

In this Aug. 26, 2014 photo, federal police and immigration vehicles patrol near the railroad tracks as a northbound freight train departs from Arriaga, Mexico. A Mexican crackdown seems to be keeping women and children off the deadly train, known as “The Beast,” that has traditionally helped thousands of migrants head north. When the authorities come, the migrants who once circulated openly in shelters and boarded the cars as they were being attached to the locomotive, are forced to hide in the woods, where criminals lurk.
