A freight train slammed into a double-decker bus at a crossing northwest of Mexico City early Monday, killing at least 10 people and injuring more than 40, authorities said.

The collision took place in an industrial area of warehouses and factories in the town of Atlacomulco, about 80 miles (130 kilometers) northwest of Mexico City.

The state of Mexico’s civil defense agency said via X that authorities were still working at the site of the crash, and the state prosecutor's office said it had opened an investigation.

The bus from the Herradura de Plata line was ripped apart by the collision.

The agency said 10 people were killed and 41 injured.

Local media reports said the injured were taken to hospitals throughout the state.

Authorities did not immediately give details about how the crash occurred.

According to the most recent report from Mexico’s Rail Transportation Regulating Agency published in September, accidents at grade-level crossings are the most common and have been on an upward trend in recent years.

Last year there were 800 compared to 602 in 2020, the report said.

The document did not include how many victims were involved in the accidents.
