Port Columbia

Port Columbia is the name of an industrial manufacturing and shipping complex in the City of Newisle's Columbia district. It serves as Newisle's only source of trade, only point of commercial naval enterprise, and only industrialized campus in the entire city. The complex has three buildings, a large container shipping terminal, and a dry storage area for ore. The port was originally called Port Redpath before being renamed in July 2020.

Facilities
The largest building in the complex is the MetroNewisle Maintenance and Storage facility, which is used to store and repair minecarts for the citywide metro system. It has links to both the S-3 lightrail line and the U-6 underground metro line. The building also has a power plant annex attached to the main building which uses goal to generate power for the entire Metro system. Plans to convert the power plant to green fuel, as well as the demolition of the building's three smokestacks, are underway.

The Newisle Smelting Company operates a smelting plant on the premises. Ore is smelted and immediately placed on containers to be shipped. There is also a storage yard adjacent to the building which stores unsmelted ore blocks.

The port owns both the large container terminal, which can hold up a maximum of 36 containers when stacked three high, and a shipping/receiving/boat storage warehouse. The dock can reasonably accommodate large container vessels 50 blocks long, but longer vessels have used the dock before.
