Georgia Department of Transportation officials have issued threats to shut down the Atlanta Streetcar because of alleged lack of efficiency, bad management and inadequately trained workers.

GDOT says it stop operations by June 14 if MARTA and Atlanta don’t develop concrete ideas to solve problems, states WXIA-TV.

What are the issues? According to GDOT, the issues include inadequate investigations of accidents, along with inadequate training and staffing, according to a letter sent by Georgia Department of Transportation Commissioner to the city.

In a letter to WSB-TV that the city has since August 2015 submitted numerous Corrective Action Plan logs and that officials are eager to receive feedback to continue the review process and to meet the agency’s requests.
