Most of the traffic requirements of Delhi commuters are met by the road transport system, which is managed by the Delhi Transport Corporation (DTC). In addition to this, electric multiple unit services were introduced on the Ring Railway in August 1982 in the suburban area of Delhi. These services originate at Nizamuddin and cover Safdarjang, Patel Nagar, Dayabasti, and New Delhi before terminating at Nizamuddin. The total distance covered is 36 km and the EMU services take about 55 min for one complete trip. Recently EMU services have also been initiated between the Delhi and New Delhi stations and the Ghaziabad station.
