Background In the early 20th century,
San Marino was poorly connected to
Romagna and the surrounding Italian countryside. The journey to
Rimini, the nearest Italian city on the
Adriatic coast, would take three hours by horse, and up to five hours by mule or ox in the winter. during planning for a railway line along the
Marecchia valley to transport sulphur from the mines in , a hamlet near
Novafeltria, to Rimini's port, San Marino indicated it would pay 50,000
lire for a station on Italian territory near its western border. In August 1926, after an impromptu visit to San Marino while on holiday in
Riccione,
Benito Mussolini, Italy's dictator, suggested that a railway line could run from Rimini to
Serravalle. He was persuaded by
Giuliano Gozi, San Marino's
de facto leader, that the line could run into the city, providing the final impetus for the railway's construction.
Construction On 26 March 1927, the governments of Italy and San Marino signed an agreement to build a railway between the City of San Marino and Rimini. Mussolini had feared that a foreign power could install a radio station in San Marino to propagate
anti-fascist propaganda. The project required 3,000 workers, with mezzanines installed to increase their capacity. including during an outbreak of
typhus in autumn 1944, after San Marino's liberation. In San Marino, the embankment between Serravalle and Domagnano was renovated into a pedestrian path through a public park, Parco Laiala.
Partial restoration On 10 June 2011, the (White-Blue Train Association) was founded to conserve the history of the railway line and promote its reopening. An original AB-03 electromotive, which was preserved in the Montale tunnel, was taken to Rome, where it was restored and refurbished.
Future development The government of San Marino supports restoring the line between the City of San Marino and Borgo Maggiore. By September 2023, the Sammarinese government had authorised extending the restored section into Piazzale della Stazione. In June 2012, , President of the
province of Rimini, suggested that the line could be restored using buses or trams, similar to the . He hypothesised that it could cost up to 40 million
euros. Vitali said that the reopening of the transport corridor could provide benefits to regional tourism while relieving congestion and improving road safety along the San Marino Highway, which Vitali noted was among the most dangerous in Italy. On 2 September 2022, Amati and
Massimo Garavaglia, Italy's
Minister of Tourism, announced that their governments had begun preliminary processes to reopen the line in its entirety. It was envisaged that the first phase would reactivate the Sammarinese section, followed by the section to Cerasolo, and finally the section to Rimini. In November 2022, Italy's Ministry of Tourism made 2 million euros available for the feasibility study. == Route ==
