Mr. Pavan - Let's see the history once ..

if I’m not wrong your comparing the two different timelines…. When SCR introduced a new train in branch line… mainline was occupied by the other trains which were running from the vishakapatnam and other states .
Vishaka - Chennai
vishaka...

- Bangalore
Vishakha to Hyderabad were there.

I’m,not sure .. may be this would be the reason.. Kakinada to Chennai and Kakinada to Bangalore was introduced in branch line
FYI kakinada - banglore train was introduced as Kakinada to Tirupathi later it was extended to Bangalore..
May be this would be the reason vishaka express was introduced in branch line since already Godavari in main line.

After ECOR formation all vishakapatnam trains got extended to bubhaneswar.. this way all mainline train became the long distance train that everybody knows.
If I’m not wrong After 2003, branch line didn’t receive any passing trains .. the trains that were starting from vskp/cct going on main line only except Vskp to LTT and cocanada.

I believe that SCR giving good connectivity from HYD to Kakinada .. Gowthami express is there likewise cocanada is there ..
After giving this much clarity.. still you belive “SCR main line ke bokka petti branch line ke preference icchandi “ then that is up to your knowledge.

Requesting you just pls go though below link.. I'm not comment anything about present situation..
I’m talking about 10 years back how everybody were reacted about present TT when it was introduced.
