Former railway line in Switzerland

The Bellinzona–Mesocco railway (; BM) was a Swiss metre gauge railway that linked the towns of Bellinzona, in the canton of Ticino, and Mesocco, in the canton of Graubünden. The line was built by the Società Anonima della Ferrovia Elettrica Bellinzona Mesocco and later became part of the Rhaetian Railway. Before complete closure, the section of the line between Castione Arbedo, and Cama was operated by the Società Esercizio Ferroviario Turistico (SEFT) as a tourist railway known as the Ferrovia Mesolcinese.

The Gotthard railway opened in 1882, providing a transport link to the communities of the valley of the Ticino River. In order to provide a link to the communities of the Val Mesolcina, a concession for the Bellinzona–Mesocco railway a committee was formed in 1891, which led to a concession being granted in 1899. The tributaries of the Moesa river carry large quantities of rock, which historically had occasionally dammed the Moesa and changed its course. The route had to be chosen for resilience to this risk, resulting in an initial estimate of CHF2.7 million. The original line was long, and rises 538.4m,

An extension under the San Bernardino Pass to Thusis was planned, in order to provide a rail connection to the Rhaetian Railway (RhB).

In 1972, all passenger traffic ceased and the line between Bellinzona and Castione Arbedo was closed, whilst freight traffic continued on the rest of the line. The B 51 passenger car is in Winterthur as a café bar on the former premises of the former Swiss Locomotive and Machine Works. The B 52 was acquired by the Brohltal railway in Germany.
