The Roma–Giardinetti railway connects the zone of Laziali (near Termini station) with Giardinetti suburb, in the city of Rome, Italy. The line is operated like a tramway.
The railway line is run by ATAC, the company responsible for public transportation in the city, which also operates the Rome Metro.
The present railway is the only part of the old and longer Roma-Fiuggi-Alatri-Frosinone railway to be in service.
The line used to reach Pantano until 2008, when the section from Giardinetti to Pantano was closed due to work on the line C of the Rome Metro. In fact the section is going to be part of the new metro line.
