The Decatur Public Transit System is the primary provider of mass transportation in Macon County, Illinois. Fourteen main routes, plus one downtown shuttle using replica trolleys, serve the region. After the removal of streetcars from the city in 1936, the private National City Lines ran the area's bus services; in 1971, voters chose in a referendum for the public to take over this duty.
