Earlier this is introduced between Secunderabad & vijayawada.
It is used to start from Secunderabad at 9 AM and reaches vijayawada by 3 PM
Later on they changed the timings
Secunderabad departure time 7:40 AM and reaches vijayawada by 1:30 PM
Then...
more... got extended to Guntur. Initial days it maintained punctuality and good speed but now a days it lost its charm. Every day it is delayed by atleast 1/2hrs delay.
