The Main North Line MNL in NZ's South Island runs from Christchurch to Picton.
The Main North Line, sometimes referred to as part of the South Island Main Trunk railway, is a railway line that runs north from Christchurch in New Zealand up the east coast of the South Island through Kaikōura and Blenheim to Picton. It is a major link in New Zealand's national rail network and offers a connection with roll-on roll-off ferries from Picton to Wellington. It was also the longest railway construction project in New Zealand's history, with the first stages built in the 1870s and not completed until 1945.
