A train which left around 1,800 migrants stranded in the Mexican desert for 24hrs is again moving towards America.
People mostly from Central & Latin America are using the tracks to enter and seek asylum. In Mexico the railroads are mostly a century old and deliberately run slowly to deter migrants.
However, last week around 30% of services were suspended due to foreign stowaways overwhelming the trains.
233,000 people crossed the US southern border alone in August. While Mexican authorities detained almost 190,000 in September.
