Columbus - With Trains!
Columbus is one of the largest cities in the United States with absolutely no light rail.
This envisions a new design, centered on the Arena District (the previous location of the now-defunct Union Station, and where other light rail stations have been proposed), with a hub-and-spoke model. The proposed center is also relatively close to the city center bus terminal, which has been included for reference.
This also adds an express line east to and from Port Columbus International Airport. The stations have been positioned to track along already-existing rail lines.
