According to the train operator Trenitalia, during the strike, high-speed trains, long-distance trains and airport express trains from Rome's Termini Station to Fiumicino Airport will run as usual.
Public transport sector employees in a number of cities are also on strike, with trams, buses, the underground and local trains suspended for the majority of the day in Rome.
The transport strike will not affect the regions of Liguria and Piedmont, which have been subjected to flooding and bad weather conditions over the last few days.
In addition to transport workers, justice sector employees will also join the nationwide strike, and the prosecutor's office and courts across Italy will be closed.
In October, the unions called a railway workers' strike over changes to working hours, an increase in the retirement age and potential privatization.
