Victims' families demand answers in deadly Mexico train crash as authorities promise to investigate

Survivors and families of the victims of a deadly train crash in southern Mexico demanded answers on Monday as the government vowed to investigate what caused a train to derail the day before on a rail line connecting the Pacific Ocean with the Gulf of Mexico. Thirteen people, including a teenager, died when the Interoceanic Train linking the states of Oaxaca and Veracruz — with 250 people on board — went off the rails on Sunday as it passed by a curve in near a town in Oaxaca. Videos from the scene show train cars that had fallen off the side of a steep hill into dense jungle below as other cars lay toppled on their side.
