The Roma–Giardinetti railway is a narrow gauge on-street railway which connects Laziali (a regional train station some 800 metres (2,625ft) from Termini's main concourse) with Giardinetti to the east just past the Grande Raccordo Anulare, Rome's orbital motorway.[1] It is run by ATAC, the company responsible for public transportation in the city, which also operates the Rome Metro.[2]
