The Treno Auditore Line (originally Forklich Main Line) is a railway starting from Eston Post all the way towards Tarrantia. The line was built by KrebsLovesFiesh in April 2018 to be a rail line that runs along the Lucek Memorial Line, but with fewer turns and stops. This line is suitable for people that are travelling from the first to the last stop because it only stops at the major interchange points along Lucek Memorial Line.
On June and July the line was adjusted to meet the existing stations of Lucek Memorial Line, which were concurrent to primitive stops made originally by KrebsLovesFiesh. August and September of 2018 the line was strongly refurbished by Ugultu and ParrotAntics in order to improve it's quality. Single track profile was changed to double track, and floating constructions of stone and redstone were replaced by proper viaducts and tunnels. Also the line was adjusted to be less dependent on ground profile, as 1:1 and 1:2 slopes were replaced by 1:3 variant.
On January 7th, 2019, the line was renamed.

- The current name of the line is related to Ezio Auditore da Firenze - a main playable character from Assassin's Creed II computer game.
- The line used to go much further than Dorklich: to Mesa Mountains. But due to limit of travelling set by operators the station became unaccessible.
- The line shares a record of the highest count of terminal station changes among all RRC lines, changing eastern terminal location 4 times (starting from Mesa Mt. to Rupflich, then to Dorklich LML, later to Dinnertime, ending in Tarrantia) and western terminal location once (from Eastern Observatory to Eston International) during it's lifetime.
