Ten people were killed and at least 61 were injured in central Mexico when a freight train smashed into a double-decker passenger bus, which the train operator said had been attempting to pass in front of the moving train, writes Reuters.

Canadian Pacific Kansas City de Mexico (CP.TO), opens new tab, the railway, expressed its condolences to the victims’ families and called on drivers to respect road signs and stop orders at railroad crossings. Bus operator Herradura de Plata did not immediately respond to a request for comment.

Images from the scene showed the front part of the top deck of the bus smashed in and its metal frame badly dented, as first responders cordoned off the area. The collision happened in an industrial zone on the highway between Atlacomulco, a town some 115 km northwest of the capital Mexico City, and Maravatio, in nearby Michoacan state, local authorities said.

The State of Mexico’s attorney general’s office said 7 women and 3 men were killed. Some of those injured were in severe condition, while others were quickly released from the hospital, it added, without giving numbers.
