Italy (Emilia Romagna) - Lines with Obscure or Sparse passenger services
This list is based on the 24 July 2021 revision to the timetable in force from 13 June 2021. Although the timetable is shown as valid until 11 December 2021, most long-distance services are shown as operating for only a few 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 monthly, as has been the case since summer 2020. In general, local services are operating as usual and many long-distance trains that had been withdrawn have been reinstated. 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.
