Twenty-seven people have now been confirmed dead and dozens injured after two passenger trains collided head-on in southern Italy on Wednesday.
The crash occurred on a single stretch of track in countryside between the small towns of Corato and Andria. Both trains were made up of four carriages.
Rescuers say they discovered the new bodies while sifting through the torn wreckage.
Several of the injured are in a critical condition and the death toll is expected to rise.
It is still unclear whether the accident was due to human error or a technical problem, on a stretch of track where safety is dependent on telephone calls rather than computer systems.
The last major rail disaster in Italy was in 2009 when a freight train derailed in Viareggio, in the centre of the country, with more than 30 people living close to the tracks killed in the subsequent fire.
