A passenger train on a test run by Chile’s state rail operator collided with a private cargo train carrying about 1,346 metric tons of copper shortly after midnight on Thursday, killing two of the cargo train’s operators.

Initial findings indicated that the passenger train was conducting speed maneuvers when it collided with the cargo train, according to local prosecutors. The passenger train was not informed of another train approaching, they said.
