(Migrants from Central and South America are creating problems).....The migrants enter Mexico at the border with Guatemala. 

Many jump onto cargo trains in Mexico that travel across the heart of Mexico to the Northern border. That is the problem. Ferromex says the migrants are injuring themselves jumping on to the trains. Some of the injuries are very serious and even fatal. Ferromex says the problem is so bad, they are suspending the trains temporarily. The rail carrier says that trains traveling north will be suspended for about 60 days to give the Mexican Government time to come up with a solution to the problem. They say some of the cargo from the trains can be transferred to semis, but they admit at least some international trade will be affected by the stoppage.
