[5] The trains were slow and the route was considered dangerous,[1][3] skirting Rimini's historic city walls and running adjacent to the SP258 [it] provincial road.

[8] On 10 March 1913, an act of parliament gave the concession for the railway's construction to the Società Anonima delle Ferrovie e Tramvie Padane [it] (FTP).

The rugged terrain of the Marecchia valley made the area difficult to connect by road, leaving the mines at Perticara valuable but isolated.

[1] On 7 September 1933,[10] through the Gestione Governativa Ferrovie Padane [it], the government temporarily assumed the management of the railway, which it would maintain until the line's closure.

[1] Following the war, the line was modified between Dogana and Pietracuta, reducing the route's length by 643 metres (2,110 feet) by crossing the San Marino river further downstream.

[12] Scartamento ridotto (1952), an early documentary by Riminese journalist Sergio Zavoli for RAI,[7] explored local views on the replacement.

[8] Farmers saw it as an innovation, while local government recognised the railway's continued economic unviability, and an interviewed conductor expressed nostalgia for the steam locomotive.

[5] Turning right (southwest) to follow the Ausa river, the line skirted Rimini's Roman amphitheatre and city walls.

[1] The line turned north at the present-day Parco Olga Bondi to reach its first station, Rimini Porta Montanara, near the eponymous gate.

After Fornaci, the railway turned on a southeasterly bearing, meeting the stations of Spadarolo, Vergiano, Casale Sarzana, Sant'Ermete, Corpolò, and Villa Verucchio.

Crossing the Marecchia at Ponte Santa Maria Maddalena, it made an S-bend, then continued southeast to Secchiano, Talamello-Campiano, and finally Novafeltria.

[5] Following the line's closure, the rolling stock was bought by the Ferrovia Circumetnea, and transported by railway to Catania in February 1961.

[17] In July 1967, "about thirty long-haired individuals, mostly minors" were arrested after taking residence in two disused wagons, causing a considerable noise disturbance.

[3] The intermediate stations, from Rimini Centrale, were: Rimini Porta Montanara, Fornaci, Spadarolo, Vergiano, Casale Sarzana, Sant'Ermete, Corpolò, Villa Verucchio, Verucchio, Dogana, San Marino-Torello, Pietracuta, Bivio San Leo, Ponte Santa Maria Maddalena, Secchiano, and Talamello-Campiano.

[5] Many station buildings are extant, including those of Rimini Porta Montanara (in a state of abandonment), Dogana, and San Marino-Torello.
