Italy (Sicilia) - 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.
Terme Vigliatore – Patti-S Piero Patti
 (ERA-E 88A4; ERA-R 168C5-168B5; S+W 103D2-104A2) IT23/201
There is a new section of main line between Terme Vigliatore and Patti-S Piero Patti, but the old route remains in use to serve intermediate stations. All trains use the new line except the relatively small number calling at intermediate stations between Terme Vigliatore and Patti-S Piero Patti. Note there is a significant grade separated junction at Terme Vigliatore.
Agrigento Bassa – Porto Empedocle Succursale
 (ERA-E 88B2; ERA-R 167C2; S+W 107C3) IT23/202
Trains usually run between Porto Empedocle and Agrigento Centrale in connection with the Sagra del Mandorlo in Fiore (almond blossom festival), which normally takes place late winter or early spring. The event was cancelled in 2020, 2021 and 2022 because of Covid-19 restrictions.
There were three round trips on Sunday 11 March 2018, departing Agrigento Centrale at 08:30, 12:30 and 15:40 and returning from Porto Empedocle Succursale at 10:14, 14:09 and 17:22.
There have been occasional other excursions to and from Porto Empedocle Succursale.
