MEXICO CITY -- Hundreds of Central American migrants trying to make their way to the United States have been stranded in Mexico in recent weeks after the freight-train line they ride -- labeled the Beast -- began enforcing a ban on stowaways, migrant advocates say.
The migrants, often desperate to leave poverty and crime in their home countries, brave riding atop the train cars, activists say, and are prey to criminals who have been accused of rape, robbery and murder.
Many of the migrants have ended up in already crowded shelters, which have reported populations now swelling beyond capacity with men, women and children. Migrant activists say that once the migrants are stranded, they face a difficult decision of whether to return home or try the journey north by foot or car, leaving them vulnerable to criminal gangs and corrupt police along the way.
Crew members of the railroad, which is featured in books and documentaries about the migration north, normally turn a blind eye to migrants scrambling to stow away on the trains.
But after the southern Mexico state of Veracruz filed a lawsuit last month accusing the railroad of complicity in the violence on the trains, the train operators began banning the stowaways, migrant advocates said. The train line is run by Ferrosur and Kansas City Southern de Mexico.
According to activists, train cars overloaded with migrants have been unhitched and left idle, and the train has skipped stops where migrants waited.
Another rail line known for carrying Central American migrants continues to allow migrants on board, according to human rights activists who advocate for Mexico's granting of travel permits so the migrants can freely head north in better conditions.
Jose Alberto Donis Rodriguez, manager of Brothers on the Road, a migrant shelter in the southern state of Oaxaca, said recently that about a third of the approximately 1,000 migrants stranded in Oaxaca for more than a week decided to continue the journey on foot.
Fray Tomas Gonzalez, head of 72 Migrants, a shelter in the state of Tabasco near the Guatemala border, said the number of migrants seeking shelter there had tripled, which he attributed both to the enforcement of the stowaway ban and growing numbers of migrants fleeing their homelands.
Officials at Ferrosur and Kansas City Southern de Mexico declined to say whether they had stepped up enforcement against those who hitch rides on the train. But in response to media queries, Ferrosur said in a news release that it had always been obliged to warn people of the "grave dangers" in boarding a freight train without authorization.
The journey has always been long and arduous, but Central Americans are increasingly taking the risk.
At the Rio Grande Valley in Texas, a popular crossing point for Central Americans, the U.S. Border Patrol made more than 90,700 apprehensions in the past six months, a 69 percent increase over last year, and an increasing number of the migrants are making claims for asylum in the United States.
Federal authorities in Mexico, which sporadically crack down on the migrants, last week arrested and prepared to deport nearly 300 migrants, most of them Hondurans, who were traveling by foot through Tabasco state.
"The Beast" stops south of the U.S. border, and migrants who make it that far then try to cross by river or through the desert.
