Italy (Lazio) - Lines with Obscure or Sparse passenger services
This list is based on the timetable in force from 15 December 2019 until 13 June 2020. Table numbers quoted here are from In Treno Tutt'Italia, the official Trenitalia timetable. Standard abbreviations are explained in General Information. Map references relate to the Schweers+Wall Atlante ferroviario d’Italia e Slovenia.
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.

Roma S Pietro – Città del Vaticano
The branch line into the Vatican City has been used since September 2015 by tourist trains to Albano Laziale, for a visit to the Ville Pontificie. Travel on the train is possible only as part of a day tour, which starts at 08:00 with a tour of the Vatican Museums, Sistine Chapel and Vatican Gardens. The train leaves from Città del Vaticano for Albano Laziale late morning. The return journey, departing late afternoon, terminates at Roma S Pietro. The train uses route IT20/124 in both directions.
Trips operate on Saturdays, but details of available dates can only be found by initiating the booking procedure on the Vatican Museums website.
There is an option of visiting the Ville Pontificie by train without a tour of the Vatican, but passengers on this trip are picked up at Roma S Pietro and do not travel from Città del Vaticano.
Tours can become fully booked well in advance.

Civitavecchia – Civitavecchia Marittima
This line diverges to the east about 2 km north of Civitavecchia and turns through 180 degrees to head back under the main line, running south into the port area. The line which previously ran direct to Marittima from south of Civitavecchia station and carried a public passenger service is now closed to all traffic.
The diesel railcar "Roma Express" is operated by Seatrain Tours between Civitavecchia Marittima and Roma S Pietro (the TrenItalia station, not the Vatican) as part of a guided day trip for cruise passengers. It is understood the train is available only to cruise passengers. There is also a "Fast Track Express" service between Civitavecchia and Roma, provided by Smart Cruise Tours, but this uses Civitavecchia FS station and does not go into the port.
