The primary mass transportation hub of Tarrant County is Fort Worth Central Station, located in the eastern portion of downtown at the intersection of Jones Street and 9th Street. About two dozen bus lines operated by Trinity Metro converge at this hub, as well as the Trinity Railway Express and TEXRail commuter rail lines. Bus service from Trinity Metro is free within certain downtown boundaries. The T operates a downtown bus circulator known as Molly The Trolley, which uses a bus designed to look like a historic trolley.
