Cass

Cass is a locality in the Selwyn District of the Canterbury region in New Zealand's South Island. It is named for Thomas Cass, an important pioneer surveyor in the area. State Highway 73 passes near the town, and the Midland Line between Christchurch and the West Coast was opened to the town in 1910, with the full line opened in 1923 when the Otira Tunnel was completed. Since November 1987, the world-famous TranzAlpine passenger train has run through the town. It is one of the few places in the world with a population of one resident.
