Italy (Marche) - Lines with Obscure or Sparse passenger services
This list is based on the timetable in force from 9 December 2018 to 8 June 2019. Several companies publish railway timetables in Italy, but table numbers quoted here are from In Treno Tutt'Italia, the official Trenitalia book. 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.
Ancona – Varano
 (55C4) IT19/91
There are two different routes between Ancona and Varano, both being single tracks. Trains generally observe left-hand running, as is usual in Italy. Accordingly, southbound trains normally use the route nearer the coast, via the longer Galleria Vallemiano tunnel, whereas northbound trains take the inland route through the shorter Galleria Castellano tunnel.
