Italian officials now report at least 13 people were killed in Friday's train crash north of the city of Bologna.
Rescuers earlier had reported 14 deaths. Officials express hope they will find no more bodies in the wreckage of the passenger and freight trains that collided in fog on the single-line track outside the northern Italian city.
Officials report more than 50 others injured, at least three of them seriously.
Rescuers say they expect to work through the night as they search the wreckage.
Officials cite the fog as a factor in the crash and say it hampered subsequent rescue efforts. But they say they are still seeking to determine the exact cause of the collision.
