MARTA is moving forward with environmental studies for a long-proposed rail line to serve central and south DeKalb County.

That work is being done even though funding for the so-called I-20 rail line is years off, agency General Manager Keith Parker recently told county commissioners.

MARTA is focused on stabilizing its finances without a fare hike for 2014, Parker said. A five-year plan calls for returning services cut during the recent recession and securing funding for new construction, such as the rail line.
