Italy (Campania) - 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 In general, local services are operating as usual and many long-distance trains that had been withdrawn have been reinstated.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.
Rocca d'Evandro-S Vittore - Bivio Cassino Sud
 (ERA-E 84B4; ERA-R 164A5; S+W 77B2) IT21/131
This route is partly in Lazio; see IT21/128
1º Bivio Caserta Nord - 2º Bivio Caserta Nord (Interconnessione Caserta Nord)
 (ERA-E 84C5; ERA-R 164A4; S+W 77C4) IT21/132
This 6.1km connecting line allows trains on the AV/AC line from Roma to Napoli to connect with the old main line from Roma to Napoli via Caserta and is used by all Frecciargento high-speed services between Roma and Foggia, Bari and Lecce.
Aversa avoiding line: S. Marcellino-Frignano – Gricignano-Teverola
[3, 85] (ERA-E 86A4; ERA-R 163A3-163B3; S+W 150C3-150D3) IT21/133
This west to east curve is used by trains between the Formia and Caserta lines, to avoid reversal at Aversa. It is used by some trains between Roma and Caserta, because the Formia route is faster than the original main line via Cassino. However, Frecciargento trains between Roma, Bari and Lecce via Caserta use the new high speed line and not this route. It is also used by trains running direct to Cancello via IT21/134.
The routing of overnight trains between Roma and the Napoli area is particularly susceptible to variation.

Gricignano-Teverola – Maddaloni-Marcianise Smistamento – Cancello
[3, 85] (ERA-E 86A4; ERA-R 163B3; S+W 150D3-151C3) IT21/134
This line, opened in 1993, provides a connection between the Roma - Napoli main line via the coast and the inland main line via Cassino, bypassing Caserta and serving Maddaloni-Marcianise marshalling yard and freight terminal en route. The following trains use the Aversa avoiding line (IT21/133 above) and this route. These are ones, other than high-speed, shown in In Treno not passing through Aversa, Caserta or Napoli Campi Flegrei. Passenger use of this route is normally limited to a small number of overnight trains, and not every night.
The following trains are diverted this way between 10 and 25 July 2021.

D10: Also via this route when departing Siracusa on 4 September 2021
Madonnelle - Volla (Circumvesuviana)
 (ERA-E 86A4; ERA-R 163B2; S+W 153A2) IT21/135
This south to north route allows trains to run between the line to San Giorgio a Cremano via Villa Visconti and the line towards Baiano without reversal.
There was an extended period when trains appeared in the Circumvesuviana timetable but did not run. However, a service comprising one return trip on weekday afternoons was observed operating in January and March 2019 and appears to have continued until early 2020.
No trains have been advertised via this route, or to Acerra, since 18 May 2020, if not earlier. It is not known if this is a temporary or permanent measure.
As and when the line is extended from Volla to the new station on the high-speed line at Afragola, there may be a service throughout the day, but it could be many years before this happens.
Linea Monte Vesuvio: Napoli Centrale (Bivio/PC Casoria) – Salerno
 (ERA-E v86A4-86B5; ERA-R 164A4-164B3; S+W 153A2-154D2) IT21/136
This line is normally used by trains between Napoli Centrale and Salerno which are not scheduled to stop intermediately. The southeast end of the line is also used thus:
- Salerno – Bivio S Lucia: Trains between Salerno and Nocera Inferiore not scheduled to stop intermediately
- Salerno – Bivio Sarno: All trains between Salerno and Sarno. This includes most overnight trains via Salerno which do not call at Napoli Centrale; these run via Cancello.
Linea Monte Vesuvio: Napoli avoiding line
[3, 86] (ERA-E 86A4; ERA-R 163B3; S+W 153A1) IT21/137
A north to east curve allows trains to run direct between the high-speed lines from Napoli to Roma and to Salerno without reversing at Napoli Centrale.

Benevento - Morcone
(ERA-E 84B5-C5; ERA-R 164B5; S+W 78B4-78B3) IT21/138
This is part of the line from Benevento to Bosco Redole, which lost its passenger service in 2013, because of a landslide. Excursions are sometimes operated to Morcone, from Napoli Centrale and from Salerno. See the Fondazione FS website for more information.
Avellino - Lioni
(EA-E 84C5-86C1; ERA-R 164B4-164C4; S+W 83B1-83D2) IT21/139

Routes used occasionally for diversions
Gricignano-Teverola – Maddaloni-Marcianise Smistamento – Maddaloni Inferiore (Bivio Maddaloni)
 (ERA-E 86A4; ERA-R 163B3; S+W 150D3-151B3) IT21/141
This is a variation on route IT21/134, but including the north-facing curve at the east end of Maddaloni-Marcianise Smistamento towards Caserta, instead of the south-facing one to Cancello. IC trains between Roma and Napoli were diverted this way on a number of occasions in 2019.
Casalnuovo di Napoli (Doppio Bivio Cassino) - Napoli S Giovanni-Barra (Doppio Bivio Marittima)
 (ERA-E 86A4; ERA-R 163B2; S+W 155D2-155D3) IT21/142
This line enables trains to run between the Cancello and Torre Annunziata lines without having to reverse at Napoli Centrale. Two southbound overnight trains were scheduled this way on some dates in summer and autumn 2020.
