Rail transport in Christchurch, the largest city on New Zealand's South Island, consists of two main trunk railway lines intersecting in the suburb of Addington, carrying mainly long-haul freight traffic but also two long distance tourist-oriented passenger trains. The two lines are the Main North Line and Main South Line, collectively but unofficially known as the South Island Main Trunk Railway. There is a heritage line at the Ferrymead Historic Park that is operated with steam, electric, and diesel motive power hauling tourist-oriented services.
