Italy (Lazio) - Lines with Obscure or Sparse passenger services
Introduction
This list is based on the timetable in force from 15 December 2024. Although the timetable is shown as valid until 14 June 2025, most long-distance services are shown as operating only for a couple of months. Such trains are not indicated by note 'D' (for a service only running on certain dates), because it is a reasonable expectation that their period of operation will be extended or a similar service is provided instead. It is assumed that the timetable will continue to be updated and reissued regularly, as has been the case since summer 2020. Users are recommended to check the Trenitalia website to ensure they are using the latest version of the timetable.
Table numbers quoted here are from In Treno Tutt'Italia, the official Trenitalia timetable. Standard abbreviations are explained here.
Map references for each route entry are given in parentheses ( ). References prefixed "ERA-E" refer to the European Railway Atlas (All-Europe Edition) by M.G. Ball. References prefixed "ERA-R" refer to the European Railway Atlas (Regional Series: Book 2) by M.G. Ball. References prefixed "S+W", or in italic, refer to Atlante ferroviaro d'Italia e Slovenia by Schweers + Wall.
Two useful symbols exist which show the booked route for trains not calling at a station: in the middle of the train column, a vertical bar "|" means that the train passes through the station without stopping, whereas a middle dot "·" means that the train does not pass through that station but instead takes a different route.

Roma San Pietro – Città del Vaticano
(ERA-E 84C1; ERA-R 162B4; S+W 149B3) IT25/143
The branch line to the Vatican City is used by a tourist train to Albano Laziale, for a visit to the Ville Pontificie. Travel on the train is possible only as part of a day tour, which starts at 08:00 with a tour of the Vatican Museums, Sistine Chapel and Vatican Gardens. The train leaves from Città del Vaticano for Albano Laziale late morning. The return journey, departing late afternoon, terminates at Roma San Pietro. The train uses route IT25/144 in both directions.
The train is normally an electric multiple-unit and the branch is wired only as far as the border between Italy and the Vatican City. The train is unable to enter the Città del Vaticano station fully and stops where the arch in the boundary wall crosses the railway.
The service was introduced in September 2015, and suspended during the Covid-19 epidemic. It resumed in April 2022, running on Saturdays, but did not run in 2024.
Details were available from the Vatican Museums website.
This line might see an increased usage during 2025, due to the Jubilee in Vatican City and Roma. It is still unknown if there will be trains on this line, and if they will be open to the public.

There are two routes between Roma Tiburtina and Roma Prenestina. Most local trains to and from the Pescara line use platforms designated Piazzale Est on the east side of Tiburtina station and run via the original curve from the former Bivio Portonaccio. A second route, next to the Pescara line, connects the Firenze – Roma Direttissima line with the Roma – Napoli Linea AV/AC via different grade-separated tunnels. This is sometimes used for diversions by high-speed trains between Firenze and Napoli if not calling at Roma Termini.
