The train is introduced to serve Hyd people to visit Prayag and Varanasi and used to run upto Varanasi only later extended to Patna. Any change in timings now will land them in night. After extention to Patna in the last 15 yrs getting a ticket or travel as become nightmare. It's time they introduce a 4 days week dedicated train to Varanasi via Prayag and then do whatever they like with this train. The original train is Tirupati Varanasi weekly with link coaches from Secunderabad operated by Dakshin express which is later made SC Varanasi.
