 Five railway workers were among the dead in the Bologna crash |
Train services across Italy are at a standstill as striking railway workers demand safety improvements. The protest follows a crash between two trains near Bologna 10 days ago, which left 17 people dead - including five rail workers.
The Italian authorities say only essential services will run during the 24-hour stoppage, which started on Sunday night.
The cause of the accident on 7 January has not yet been identified.
A regional express train collided head-on with a freight train, derailing its engine as the goods train ploughed into passenger carriages.
Preliminary investigations have suggested that one of the two trains involved in the crash failed to stop at a red signal.
