Paragon Transit Authority
The Paragon Transit Authority, or PTA, is the semi-private organization that oversees and manages all forms of transportation in Paragon City and the outlying areas.
The PTA started out as the Paragon Rail Company in 1912 following a series of violent riots involving rival rail companies. Their name was changed in 1951, and their scope eventually expanded to include monorail service and the ferry service between Talos and Peregrine Islands.
In 2002, the Rikti destroyed much of the Red Line service in their inital attack. In memory of that service, all PTA railcars bore the "Red Line" sign. Parts of the original Red Line service can be seen in the ruins of Baumton.
In 2010, the Yellow and Green Line Rails were merged into one system, allowing commuters to travel anywhere in Paragon City and Croatoa, with the obvious exceptions of the areas deemed a Hazard Zone.
