Italy (Sardegna) - Lines with Obscure or Sparse passenger services
This list is based on the timetable in force from 11 December 2022. Although the timetable is shown as valid until 10 June 2023, most long-distance services are shown as operating only until March. 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 in General Information.
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 - Italy) 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 dot "." means that the train does not pass through that station but instead takes a different route.

Ferrovie della Sardegna obscure services
Limited services, marketed as Il Trenino Verde della Sardegna, normally operate over the following Ferrovie della Sardegna lines, mainly during the summer. There are less frequent public excursions at other times. Details are shown on website www.treninoverde.com, but it should be noted that these may vary in practice, particularly if there are insufficient advance bookings. It is also possible to charter trains.
Proposals to close all lines which do not have year-round passenger traffic have been dropped in favour of plans to rehabilitate them, but some have been shut for over five years. Traffic was suspended from 24 June 2016 between Laconi and Sorgono and between Seui and Arbatax, because of the poor condition of some bridges. The line between Gairo and Arbatax re-opened for the 2017 season. Services resumed over the full length of the line between Macomer and Bosa Marina in 2021, but there was no service in 2022.
Changes in 2023 are that the service from Tempio Pausiana is extended from Luras to Arzachena, but the line thence to Palau remains without service. Macomer to Bosa Marina is reinstated. The service between Mandas and Seui is cut back to Flumendosa (between Villanova Tulo and Betilli) and the service between Arbatax and Gairo is cut back to Lanusei.
The advertised service in 2023 is:
