They were about 1,500 miles south of the US-Mexico border as they started heading northwest to the city of Celaya.As the train slowed down, migrants scrambled around the train cars to find a way to climb aboard, throwing small bags of belongings onto the train and hastily helping one another.Police and guards watched from a few feet away. Some took photos. None took action to stop the migrants as they climbed the train.Gabriela Hernandez of Honduras handed her toddler to another migrant who pulled him up. Then, she pushed her 6-year-old boy up the ladder. When it was Hernandez's turn, the pregnant 27-year-old struggled to find the strength to pull herself onto the train.With help from others, Hernandez swung her leg onto the top of the car only to find a massive pile of scrap metal and trash. She will have to sit on the pile for hours until she reaches the next destination. She grabbed her two boys tightly, sat on a blanket above the pile and sobbed as her two boys consoled her.Hernandez said she is exhausted."It's difficult, but I will have to find the strength to carry on," she said.As migrants set makeshift tents with blankets to protect them from the dusty wind and scorching sun, people from the ground and a bridge above waved.

She insisted the migrants are not dangerous, and that they are just families escaping violence.She called for her daughter to show evidence of the violence she is fleeing in Honduras. Pulling the young girl's shirt over her shoulder to show the scars, she explained that the gang in her neighborhood set her house on fire last year. She managed to pull her three children out of the home, but not in time to save her daughter from the burns that have scarred her face, arms and stomach."I can't go back to Honduras," she said.Laura said she doesn't know anyone in the United States but wants to reach the border to seek asylum. Like many of the families traveling with the caravan, she said she wants her children to attend school without having to worry about gangs, and she dreams of a better life for her family. 3262
