 Valetta was formerly served by the Mount Somers Branch, a branch line railway that diverged from the Main South Line at Tinwald, New Zealand, just south of Ashburton.On 3 October 1882, the Westerfield to Anama section of the line opened with a station in Valetta.Passengers ceased to be served by the railway on 9 January 1933 due to declining patronage as a result of increased private ownership of motor vehicles, but freight traffic stayed steady until after World War II.
