The secondary railways reached a total of almost 1,000 kilometres of length.1933 The SFSS company was transferred to the "Strade Ferrate of Puglia" with head office in Genoa, holder of concessions for other railways in Puglia in Italy, which in the same year changed its corporate name in "Strade Ferrate Sarde" (SFS).
This company also purchased the FCS and from then on SFS and FCS were under the same control with managing director the count lawyer Pasquini.
During the Second World War many points of the railways were bombed (Cagliari, Macomer, Arbatax stations); however, the rail was useful for thousands of people who wanted to leave the city and reach the quieter villages in the inland.
From the '50s it began the process of substituting railways lines with coach services on the following lines:
1956 (1st July) Isili-Villacidro and Villamar-Ales; (14th September) Gairo-Jerzu.
1958 (21st July) Luras-Monti.
1969 (31st December) Chilivani-Ozieri-Tirso.
1971 The Company was no longer private and it was transformed into a Government Management run by a Commissioner.
1974 The FMS railway network was definitively closed with a coach service in substitution of the links by train.
1989 (1st January) The new company "Ferrovie della Sardegna" (FdS) was created from the merger of the two companies FCS and SFS.
1997 The FdS were assigned to Ferrovie dello Stato.
2002 (1st January) The FdS are once more run by a Government Commissioner appointed by the Minister of Transport.
2008 (June) The FdS are transferred from the Ministry of transport to regional administration and transformed in ARST Gestione FdS limited company that is wholly controlled by ARST corporation.
