Italy - Lines with Obscure or Sparse passenger services
This list is based on the timetable in force until 10 December 2011, unless otherwise stated. Several companies publish railway timetables in Italy, but table numbers quoted here are from In Treno, the official Trenitalia book. Standard abbreviations are explained in General Information.
Westbound and northbound trains normally have even train numbers. Eastbound and southbound trains normally have odd numbers. Trains may, therefore, have several numbers during the course of a journey. For example, the 07:13 Bergamo to Ventimiglia, which runs west to Milano, south to Genova and then west again, is successively IR1786, IR1787 and IR1788. In the tables below the train number used is that applicable at the last stop before the route concerned. Where two train numbers are shown, that is because they vary with the day of operation. Trains running on only a few days during the Christmas and New Year holiday period are not included in the lists; none use lines without any other passenger service.
Passengers without cars may make reservations on Auto al Seguito car-carrying trains marked Aa within 15 days prior to departure, if any places remain available.
Lines are listed in geographic order, from north to south, grouped by region. However, the Firenze - Roma direttissima (which passes through the regions of Toscana, Umbria and Lazio) is shown as a separate group. Special Notes and details of Linea Alta Velocità (High Speed Lines), Other Sparse Services and Deletions since previous edition can be found at the end of this page.
List of Regions:-
- Lombardia (includes Milano)
- Trentino Alto Adige
- Piemonte (includes Torino)
- Liguria (includes Genova)
- Emilia Romagna (includes Bologna)
- Toscana (includes Firenze)
- Firenze - Roma direttissima
- Lazio (includes Roma)
- Campania (includes Napoli)
The following regions currently have no Obscure Services: Abruzzo, Basilicata, Friuli Venezia Giulia, Marche, Molise, Puglia and Valle d'Aosta.
The Trenitalia timetables suggest that on certain lines fast trains and stopping trains run via different routes, but in fact there is a quadruple line with station platforms on only one pair of tracks. Such lines include Prato Centrale to Firenze Rifredi and Padova to Venezia Mestre.
Linea Alta Velocità (High Speed Lines)
The following High Speed Lines, which are electrified at 25 KV 50 Hz rather than the standard Italian 3,000 Volts DC, are used by Alta Velocità trains. These are shown in timetables as type ‘AV’ and are marketed as Frecciarossa, Frecciabianca and Frecciargento.
- Torino Stura – Milano (Rho Fiera)
- Milano (Bivio Melegnano) – Bologna (Bivio Castelfranco Est)
- Bologna (S Ruffillo) – Firenze (Castello)
- Roma (Prenestina) – Napoli (Gianturco)
There are various intermediate connections between these lines and older routes. The only one over which passenger trains operate is that at Caserta Nord, which is used by AV trains between Roma, Bari and Lecce.
There are also high speed lines electrified at 3,000 Volts DC, which may be used by other trains:
- Milano Lambrate – Treviglio: See IT11/12
- Milano Rogoredo – Tavazzano (Bivio Melegnano): See IT11/13
- Padova – Venezia Mestre: This is effectively a quadrupling of the old main line.
- Roma – Firenze Direttissima: This is an older high-speed line. See separate details.
- Napoli – Salerno: See IT11/132
