Commuter rail service in Catalonia, Spain, was suspended Wednesday after a Barcelona train crash killed one person and injured 37 others. The crash happened Tuesday night when a train hit a retaining wall near Gelida. This incident follows Spain's worst railway disaster since 2013, which occurred Sunday in southern Spain, raising the death toll to 43. Authorities are investigating both crashes. Rail disruptions Wednesday caused significant traffic jams into Barcelona. Spain's railway operator said heavy rainfall likely caused the retaining wall to collapse. Three days of national mourning are underway as officials continue their investigations.

Survivors and families of the victims of a deadly train crash in southern Mexico are demanding answers as the government vows to investigate what caused a train to derail 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. Nearly 110 people were injured. President Claudia Sheinbaum, told reporters on Monday she was heading to the region and promised an investigation. She said "our first priority is taking care of the victims."
