A unique line with a combined train and barge freight transport system. The construction of the Palazzolo sull’Oglio-Paratico Sarnico railway line began in 1874 and was completed in 1876 by the Upper Italian Railways Company. It primarily served to connect the iron and steel industries of Lake Iseo with the Milan-Venice main line and for the transport of limestone from the quarries of the Brescia side of Sebino to the Palazzolo cement factory, the first factory established in Italy for the production of hydraulic lime. The train replaced water transport on the Fusia canal, which had been used until then. The line branches off in Palazzolo from the Brescia-Bergamo line, which is in turn connected in Rovato to the Milan-Venice line, heading north, along the Oglio valley. It reaches Lake Iseo in the municipality of Paratico, along the border with Sarnico, hence the double name of the terminus station. The definitive operating concession was granted in 1880 to the Anonymous Company for the Palazzolo-Paratico railway at Lake Iseo. In 1911, the railway was acquired by the State Railways, which continued the freight and passenger service. The latter, always secondary to freight transport, was suppressed in 1966, while freight traffic continued until 1998. In the meantime, tourist trains had begun to run on the line, a service that the Fondazione FS resumed in 2014.
