Circar is alternative to mail during night time from Vijayawada to Chennai and stoppages are given some 30+ years back to provide connectivity as it's local train compared to all long distance trains and running from town and small city. Like cicar stoppages are provided for Tirupati Howrah, Krishna, Golconda, simhadri. Later from 1992 new series of trains are introduced with less stoppages. U cannot compare these legend stoppages of four with other trains as they are only express trains used to cater small towns before 1990.
